Yep it won't function at all in glocks or 9mm PCC's, there are a few pistols it will cycle in but it completely wears out the magazine feed lips in a few hundred rounds, plus it's extremely corrosive and will destroy any type of finish or coating, all while shooting 36" groups at 7yds... and don't even get me started on how terrible and inconsistent Winchester white box is! People should definitely only buy Remington brand 9mm.
Berry Reading .... Yup Berry, that’s correct. Thank you for reminding us all. We should probably warn everyone about the side-effects as well..... it usually causes halitosis, shrinking testicles, loss of brain cells, and of course... herpes simplex 7. Funny how nobody talks about that anymore.
I'm far from a firearms expert but I have always heard steel case will wear down your extractor faster than brass. It seems plausible seeing as steel is harder than brass but on the other hand extractors are still made from way harder steel than cheap steal cases.
🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸♥️♥️♥️♥️🌎🌎🌎🍓🍓🤪I'm a 69 year old man from San Antonio, and I have a 9mm, .40s&w, .45acp, and a .357 magnum, and a I like everything this 47 year old lady says.
Good video!! Being on a budget, I look for the cheapest ammo I can find, and yes, have been known to throw them all in a range bag, steel and brass, and shoot them all mixed in the mags. No issues so far
whatisjustice I am mostly an AK shooter, 5.45x39 and 7.62x39, I have 2 AR's I have assembled, mostly just for fun, and remembering my time in the military. Doesn't hurt to learn them all.
C Kim ...I tell ya what though it’s a prickly world out there in pistol land. Folks tend to get their feelings hurt real easy. Not me though, as long as you agree that M&P ‘s are the best...lol
Can we just stop and appreciate how good of a fucking day that was when you filmed this? Not a cloud in sight. I wouldn't know what to do, too many options hehe
The only steel cased ammo I've ever had problems with was the Winchester forged. Ran countless rounds of Wolf, Tula, and Brown Bear through my pistols with zero issues. Keep up the good work MAC, love the videos.
I have personally seen quite a few issues with steel cased 223 getting stuck in chambers. The fact that you have never had a stuck case is impressive, or maybe its that you usually aren't shooting low end ARs that might be more prone to problems.
@@johngraham9816 depends on the steel cased ammo for the most part i run wolf ammo threw my ar and my 9mm and if its got the polymer coating stuff you are fine lacquered steel case is typical trash but i get stuff that will run and wolf hasnt done me wrong its a little dirtier but no corrosion wear. I say this cause i buy alot of surplus ammo.
I recently bought & used 9mm steel case ammo for the first time & my guns had no issues at all. From now on I will continue purchasing steel case ammo. Thanks for all of the videos you share with us. -Marco
s0nspark First magazine had a failure to extract on my p07 with steel ammo. However after 100 rounds of brass it hasn't had a problem since. The gun was extremely stiff then, it isn't now.
I love your sense of humor! It probably disturbs a lot of people but I get a big charge out of it. I just bought a lot of Steel for several different Investments. This is a wonderful time for me to say thank you.
I remember when steel cased ammo was lacquer coated before polymer coated steel cased ammo. Maybe that is how the failure to extract issue came into being. The lacquer would melt and gum up in a hot chamber and make a fired case stick. That is just what I heard I never experienced it myself. In reference to the CZ P07 I own one and have own other CZ handguns in past. I have yet experienced one fail. CZ's are deadnuts reliable.
Its very true old military surplus is dunked in lacquer ive seen it happen in person it took achamber hone to get the melted heat bonded mess out of the gun
Yes, the ar ammo is different than 9mm. When Wolf first started making ar ammo it was lacquer coated. The coating would melt in a hot chamber and cause issues, they then switched to polymer coatings and the issue was resolved. I have seen this with 9mm also. Some of the early 9mm had a lacquer coating. I believe the recent 9mm does not.
I shoot surplus lacquer coated steel ammo through my SKS and have had no issues, she's gotten pretty hot and dirty a few times too, but like he said the 7.62x39 round shape helps it not stick. And I tear the rifle apart and clean it top to bottom every time I use it religiously so that definitely helps too. Haven't tried steel cased pistol ammo yet.
I've heard this same myth. While I never had that issue in handguns, I figured it may be true for straight wall rifle cases. Thanks for being awesome Tim.
What would be a better test would be to clean and get running with no issues your Sig P365, since that is the firearm you had the issues with. Run brass first (to confirm function), then run steel, then run brass again. The potential issue may be more likely in certain guns.
When I've heard of this is was with lacquer coated steel cased ammo in AR15's and it was over the course of at least a few hundred rounds, enough to get the gun hot which softens the lacquer supposedly. I've personally seen it happen once with a friend's AR but there's no way to know for certain that that actually was the cause. I still shoot lots of steel cased ammo but I have dedicated range/practice guns and separate carry/defensive guns.
Tim I counted and that was only 99 rounds of steel ammo. If it would have been a 100 even it would have happened for sure!! LOL I've done the same thing and have NEVER had an issue. I've even mixed in the same mag before on the last mag of the day. Thanks for all the work you do for us in making these videos!
Thanks Tim for busting these myths. I have never had this happen to any of my firearms ether. The people that come up with these myths don't know anything about firearms a ballistics. Also i shot both steel cases and they work just fine. Keep up busting those myths bro.
The problem I had with steel was associated with the lacquer that used to be on all steel cased ammunition. Some of the lacquer would transfer to the chamber while shooting. Wolf actually came out with that polyformance coating to eliminate that issue. I noticed the issue with Wolf 7.62x39, but not other Russian brands.
I don't listen to the What If Brigade! When a case gets stuck it is usually because the extractor did not grab onto the rim and that can be caused by several things. Good video MAC.
MrSumGuns i used to exclusively shoot steel cased ammo in my ar15’s until i got 3 cases unbelievably stuck in 3 different ar’s in one day rendering the gun useless without some sort of rod to knock it out. Also had a rifle rip the rim of the case off, had to get it out with a wall anchor from home depot
Ammo is hard to find right now. So i run whatever i can find through my g3c, which ends up being mostly wolf. ZERO issues ever. Taurus came a long way with the new g3c!
Well done video.... getting my first fire arm after retiring from the Army about 6 years ago. Just needed to get brushed up on what's out there. I'll buy what is more affordable and do what every gun owner should be doing.... keep their weapon clean...
Hey Tim, first off thank you for your service. I have to say that I have had more trouble with Winchester white box than I ever had with tulammo. I mean sure it’s dirty, but CLP seems to work just fine for clean up. I do tend to buy a lot of the federal aluminum case to because it’s a pretty good value as well. In either case I have no trouble with either of them.
I've been shooting hardcore for around 25 years. Not once have I had an issue with steel case ammo of any brand. As far as steel casing not sealing as much as brass....just clean the machine after each use. Thanks, MAC
polish the first 3 plus inches of the breech[ barrel] and make sure your extractor is functioning and you should be good ! thanks for the hard work and info ,i agree!
I always thought the steel case ammo causing brass to stick myth was back in 80s and 90s when the steel case ammo had lacquer coated cases. Maybe it is still coated the same? Idk..... I appreciate the test Tim!
As far as I can tell, TulAmmo still is. The cases on that Wolf ammo looked like it was dull grey and uncoated, unlike the TulAmmo I've used, and cursed at, and never bought any more of.
I've never heard of this myth before now. I've fired thousands of rounds through all my firearms and never had an issue when combining steel, brass or aluminum case. In fact, I usually put my firearms through hell, at the start, so that I can get an idea of their limits. So I've fired low to high end ammunition and even poor to good reloads. I don't think the case has anything to do with it. There is only 3 things (other than broken parts) that I can think of that would cause your pistol to fail like this. 1. You are using a cheaply made/poorly manufactured pistol to begin with. 2. You are not maintaining your pistol properly (cleaning). 3. You are using polymer coated ammunition in a low caliber semi auto pistol. (or even rifle) #3 is from personal experience. I've noticed that the polymer coat will sometimes rub against the entrance of the barrel when loading. After a couple hundred shots you'll get a small build up at the entrance, causing your shell to stick.
I did a test a long time ago on steel cased and brass differences. When you fire a brass case, the brass case expands a bit then retracts. It makes the extraction easier because it retracts. This was measured with a Micrometer before firing and after firing. The Steel cased ammo when fired would expand then not retract as much. It would still be snug in the chamber and would be harder to extract.
My Smith M&P AR15 will not eject steel case ammo. I’ve tried several times over the years. My AK and my M1A eat steel all day long and never complain. I’ve never tried to shoot any steel case handgun ammo.
CZ P07 (Duty) will shoot any ammo I feed it. I did have an issue with weak magazine springs but that was cured by replacing them. Now every magazine works as intended. Thanks for the video.
My RRA AR15, which does have a Wylde chamber/barrel(almost positive it's chrome lined) and I can and have consistently been able to get brass cases to stick after shooting wolf lacquer ammo. 1 mag of steel cased ammo, and I will get a stuck brass case. I've tested this on 5 occasions, and it stuck every time. I've never had a stuck case in this rifle outside of this situation. I don't shoot steel cased out of any of my other AR's so I don't have that information. Sometimes I'm able to butt strike and get the case out, most times I have to tap it out with a cleaning rod. I just make sure I take my chamber brush with me, and brush out the chamber before shooting brass and it's fine.
O4 HEMI besides running self defense ammo through my p07 once a month,it eats wolf and Tula almost exclusively. To this day zero malfuction and at 2000 rds later still going strong. It's also my daily carry.
Happy to see the P-07 as I own a P-09 in .40 S&W myself. An interesting encounter I had myself Is my Ruger AR-556 (which is not chrome lined) has in fact had this issue with steel case ammo shot before brass cased ammo caused the rim of the casing to tear off failing to extract. In my tested though this issue only occurred with freedom munitions re-manufactured M855 ball the second I ran American Eagle XM193 this issue ceased. A quick chamber cleaning made the M855 shootable again without malfunction. I think this only fortifies your claim though early on in the video. (Cool video I did enjoy it alot!!!)
Had it happen in a ruger mini 30. The steel itself isn’t the problem, it’s the lacquer coated stuff that does. The lacquer cooks off the casing and deposits on the chamber.
Great video!!! I've never had this problem in my Gen 1 P07. I put 300 rounds of steel cased when i first got it and have since fired close to 12k brass and not one malfunction
I’ve heard all the reasons why not to use steel as well. I’ve never used it due to the manufacturers clearly state not to. I have the kind of luck that my gun would explode and somehow they could tell it was steel case ammunition. I don’t think that would happen, but that’s my only reason. I’m getting too old to pick up brass. With steel I could buy one of those magnets to save my back.
thats why i bought the eaa witness 10mm combat sport elite. it never gets hot and never fails a singal round no matter what casing it has. and is dead accurate . it tops cz if you ask me. its the better clone of cz.
I really wanted the P365 to succeed and I hope Sig fixes these bugs. I really like the specs on it and really wanted to get one for a carry gun but I'm glad I held out, for now.
We need to have many more people to do this exact test with many different firearms to conclude with high certainty that this is not a problem. I don't believe that this is a problem and I think your 30 years of experience is also a good case against this myth. I am just being critical of one test with one firearm is simply not enough data to conclude with high certainty but I like your attitude and your will to test things KEEP IT UP!
Love your channel! I just tried my first 200 rounds of steel case ammo. The cz75 sp01 I was using has not been cleaned for about 1k rounds using brass. I then shot the steel case ammo. Worked great. Then went back to my blazer brass for about another 200 rounds. There were no failures to extract or any other problems. However the speed at which the brass shells were getting ejected were noticeably slower. They just sort of limped out of the gun dropping pretty much at my feet instead of shooting off 5 or 6 feet away. Even YOUR ejection pattern on the first 3 shots of the brass looked noticeably slower. There is something there to the MYTH!!!
What is true is that if you accidentally close a tab in most browsers on a computer, CTRL SHIFT T, reopens it! (Command-Key Shift T, for Mac) This has absolutely nothing to do with the video, just thought I'd share that.
I’m on my second glock roughly 5k rounds between the two and have never been hit anywhere around the face nor my body in general for that matter, am I missing something?
I agreed with you 6 years ago with the Wolf ammo vid you produced, I've never fired it in a handgun because I can't use it at my range but I doubt it's any different than the several dozen cases of steel case rifle amp I've shot in my 30 plus years of shooting.
Glad you posted this. I'm 21 and in my area, 350 rds of blazerbrass 9mm costs the same as 500 rds of winchester steel case 9mm. I have a carry gun that only runs brass case, but my practice g19 runs steel almost exclusively. I save 20 - 30 dollars a session. This adds up when you go at least 3 times a month. Being young I just don't have the cake to run premium ammo. Also, this candy glock trend I'm seeing cracks me up; dudes will spend 1500$ on a gun we all know they maybe have 200rds through. No wonder glocks are getting hate recently.
Probably the same folks who claim you'll run into legal trouble using "gimmick" ammo in self defense. Keep doing what you're doing, Tim. To hell with the haters lol.
Kurt Feltenberger name a single case where that has happened? BTW that BS was a hypothetical proposed by lawyers who shoot in a discussion on some gun forums. Later Ayood mirrored similar concerns. And Boom, from that and over time it morphed into, it IS something an overzealous prosecutor will use. And if it were ever brought up. Any lawyer worth their salt can easily dismiss that when they bring up the fact that modern self-defense ammunition in use by civilians and LE uses expanding rounds.
It is just one of a couple dozen things you can do that will make your lawyer's job easier if you have to use your gun in self defense. Will that, by itself, mean you are in trouble? No. It is just something an anti-gun lawyer can throw at a gullible jury to which your lawyer will have to respond. Hopefully, any case we might be involved in will be straightforward and it won't matter in the end.
Kurt Feltenberger That's only a concern if you have hired a poor defense attorney. In almost all cases of a self-defense shooting, the ammunition, caliber, and weapon are immaterial in determining your guilt. If a prosecutor brings that up and your attorney doesn't immediately object on the grounds that it is entirely irrelevant, you hired a bad attorney. What's relevant is whether the suspect either posed a legitimate threat to your life or a perceived threat (depending how the relevant law is written) and whether you used appropriate force to deal with it. That's it. I know of only one case in which the caliber was even brought up as a potential relevant detail. That was the trial of Harold Fish, but even then the prosecutor didn't wind up being able to go after him for the 10mm. It was shut down almost immediately. Ultimately, your ammunition choice is almost never going to be any kind of relevant factor in your trial. The only time it might be an issue is if the ammo overpenetrates and hits a bystander or if an improper cartridge causes injury to someone. The law isn't magic and lawyers aren't wizards. You won't be put away for using R.I.P. or Zombie Defense ammo unless it has been specifically prohibited in your jurisdiction. I applaud your decision not to use gimmick ammo, but only because it's usually inferior to or identical to and more expensive than actual, proper defensive ammunition.
Hi , I think most of the steel case ammo myths come from the fact that a lot of the steel cased ammo being imported was cheaply made crap with poor quality control. The problems were due to the dimensions being out of spec,and the rounds being used in a tight chamber, not the material the case was made from.
Zac Dempsey I agree Wolf is some good ammo, have had issues with.Brown bear and Tula though. My glock 19 will feed it ,but my vintage high power and cz 75 don't like it.
I recently read that Ruger commonly has tight AR chambers, and I have had stuck steel cases a few times over the years in my SR-556. I also picked up the notion somewhere that firing a few brass cased rounds will "grab" any carbon deposits and pull them out, cleaning out the chamber. Could be BS, but more plausible than the myth Tim busted.
Larry is right IMO. I still have some old (10 plus years) Wold steel case and it is dimensionally out of spec. It will not drop freely into a 5.56x45 chamber and needs a slight nudge. This same anmo also causes nothing but issues in one of my piston guns. Problem with steel case is the majority of it comes from overseas and QC is always questionable.
Actually the real source is LuckyGunner, but not because they put bad info but because people extrapolated and made conclusions where there were none. www.luckygunner.com/labs/brass-vs-steel-cased-ammo/ "When heated, steel does not expand and contract the same way that brass does - in fact, brass expands 1.5 times as much as steel. The shape of the .223/5.56 case was designed with brass as the case material; this plus the fact that steel doesn’t expand - and more importantly, contract - like brass means that extraction will be naturally more difficult." Note the comment section and how some people are saying things that LC never even wrote. Steel cases will jam up if followed by a brass case but this only happens on rifle cases not handgun cartridges, as MAC notes in the video. Plus this primarily happens on 5.56, usually not on 308 where the port pressure seems to be strong enough to rip the case out in my own experiences (the brass is darkened after firing showing it is pulling out some fouling). Ironically, in an attempt to bust a real myth, MAC has accidentally started a new one. There are people who now say that steel case never has extraction issues and any claim of that is fake, when you can indeed have extraction issues by shooting a bunch of steel in rifle then switching to brass without cleaning the chamber. I have personally seen a steel to brass case jam and never knew why until LC posted their article. Really nearly all myths start where someone takes someone else's words out of context, and people run with it. Kind of like how democrats say Trump is a racist who says Mexicans are rapists, even though anyone can see the clip of Trump saying rapists and drug dealers are among illegal aliens (which ironically does not imply nationality, but the leftists went with the stereotype).
I'm with you MAC I've never had problems like that. I've had problems with Remington brass factory loads Sticking or explode out the primer pockets and busting my bolts. I will not use there ammo ever again.
👍good information.... My s&w m&p AR-15 i would bring 200rds of wolf ammo an around 190rds i would get a case stuck.failure to extract an the rim of the case was gone.i tryed mortaring the rifle..nothing so if i shoot steel i keep the cleaning rod out an on the rifle.rubber bands or Velcro/zip ties..this is just this rifle. My COLT i shot 1000 rds no problem green laq. Wolf..just my experiences.good luck
lucky43113 I been using brass for class.. Lots of gun ranges by me won't. Let me shoot steel ammo only 2 gun ranges.so buying brass ammo is safe to shoot anywhere.
Excellent video! I too have never had any problems mixing steel cased ammo and brass ones. Hell, I have even mixed them in the same magazine, with no bad results. Thanks!
I purchased 4 boxes of 250 round 9mm. Apparently 1 box was steel case and i didn't realize till i got home. I said oh well, i will fire these off 1st. So i put most of them in my SW Response AR15, some in my Glock G45 and some in my Canik TP9-SFX .... All fired fine, the Canik and Glock had some nice "fire" at the end of the barrel which was cool looking, i dont ever see that with brass case ammo.
This is a pistol, and pistols have much shorter case lengths than rifles do, meaning less friction. Pistols are also typically some form of delayed blowback (recoil-operated, roller-locked, etc.), not locked-bolt gas-operated, so their initial extraction impulse is more positive and the slide and barrel start moving instantly, allowing for some case movement. Static friction is a lot harder to overcome than kinetic friction, and because a pistol-style action allows some degree of movement right from the start, it's always in kinetic friction from the moment it starts to expand. A locked breech rifle, though, is in static friction until the bolt rotates and unlocks, allowing it to properly set up, and the longer case walls further increase said friction. tl;dr, different case lengths and completely different action types mean a test that's valid for pistols isn't necessarily valid for rifles.
What you're spouting is just so much male bovine feces! God only knows how much Chinese, Russian and other steel-cased crap I fired downrange as a police firearms instructor. Never, repeat, never did I or any of my students experience any stuck cases. A few (less than 0.1%) were FTF's, but no stuck ones. Rifles, pistols and revolvers; same results. They weren't always the most accurate ammo, but it got the job done!
@@davidberry6046 Yes, and I imagine these firearms got cleaned before being reloaded with brass-cased duty ammo. As long as you keep shooting steel, it's fine. But it's when you change back to brass without cleaning properly first that you run into problems.
When the S&W M&P auto pistols first came out, I bought a 9C version of it and took it to the range with several boxes of Wolf steel cased 9mm. After several mags full of fairly fast shooting, the action failed to open when a round was fired. I couldn't budge it with all my might. I took it to the gunsmith locally, and he said the lacquer on the Wolf ammo had melted in the chamber and glued the case in there. After that, I swore off steel cased ammo.
I shoot mostly wolf Barnaul ammo, more specifically the lacquered milspec ammo. I hear people at the range all the time tell me they won't shoot that garbage because the lacquer melts and causes cases to stick. It's crazy, for $200/1000rds of 556 or 545 I'll deal with the extra smoke and get more range time for the money. I've had more problems out of brass ammo than steel.
That's old myth has been going around for decades. It's hogwash, as you know, but Wolf actually changed the coating because they go so tired of the misinformation. Sadly, it's just shifted to people saying that carbon build us due to the use of steel is the real problem. Meanwhile, many nations continue to use steel cased ammo with lacquer without issue. I should make a video of a 5.45x39 spent case with lacquer with me holding a propane torch to it. It's interesting to do because that lacquer does not come off even with extremely high temps.
Spanky's Basement but what about the ammunition that Iraqveteran8888 was running through that AK when it started gunking up the action? I've never bought lacquered ammo so I'm not sure if we're talking about the same thing but the ammo I'm talking about had some sort of lacquer or something around the primer that was melting.
Re:iv8888 meltdown. That was an issue with the primer sealant flaking off (not melting) and gumming up the firing pin channel. Not the case coating. It had nothing to do with the steel case.
kyle eaton That is primer sealant, it keeps moisture out if the ammo for long term storage. It does come off but I've never had it cause a malfunction, I shoot 2500rds one day with my AR using the Echo trigger and had no issues other than some light primer stikes which happens even with PPU ammo. I blame the trigger for that.
I shoot an assload of steel case ammo i literally never have any problems with it. Those guys were just stupid. I sometimes have a hug bag of mixed brass and steel and aluminum and shoot it have no problems
A-men, most of the failures I have witnessed, and had come to the shop have been caused by the appendage attached to the trigger finger, and the absence of grey matter with which to lube the tendons that expelled any usable knowledge
Thanks for this video; I also weary of the steel-case bashing, when that's just about all I run in rifles and pistols. I I did have a brass case stick in my (chrome-lined) SU16 and I ruined an aluminum cleaning rod driving it out. I had shot steel previously; since giving the chamber a good scrub, there have been no problems. In your earlier video about Wolf ammo, ISTR that you had mentioned fouling in rifle chambers as a more likely cause than lacquer or polymer melting, but it was still rare. I have often used that video to try to lay to rest 'steel is crap' arguments.
Marcus Locklear: Congratulations on your purchase. I'm sure you'll be happy with it and spend many happy hours at the range or elsewhere. In case you are wondering, this is a sincere statement, with no sarcasm intended.
Most failures to feed or eject are caused by some defect in the gun itself, holding the gun wrong when firing (usually limp-wristing), or by an improperly made round, not by the material used to make the case of the round.
I have shot about 2000 rounds of wolf steel cased through a glock 19. The only problem that I have ever seen is that the magazines get fouled and the rounds start to stick and wont feed. The solution is to brush out the mags and keep going. Other than that, steel cased ammo works just fine. If anything, the brass case ammo "feels" better after shooting the steel cased stuff. Thanks for the good content.
The only steel cased ammo I've ever had any problems at all with was some old steel cased .22 ammo from Russia, in a 10/22. I bought it in 1974, and it caused the brass to occasionally stick. I had more failures to extract with the steel, when I could get it to even function at all. I still have half the carton, but it seems to function fine now. 44 years later!
Was it the steel then brass or poor gun maintenance, My point is if the myth were true then it would happen every time with every fire arm. Folks have told me that using 7.62x51 in a Remington 700 hunting rifle is dangerous because it is over pressure. Did I believe that NO, any gun ammo combo has the potential for failure, it does not follow that every failure is going to carry to every gun.
Tom Ollie im not a die hard brass fan boy but every time ive used steel it has choked the gun. Hard stoppages. Mainly rifles, never had an issue with pistols
Tom Ollie I’ve had numerous issues using steel case ammo in many different types of firearms. AK’s fire steel case no problem because they’re over gassed like no ones business. I’ve found some handguns can shoot them all day long and others can’t. Even my wife’s G19 will gum up with the nasty Winchester USA Forged steel case crap.
Steel Talon I find that the Tula ammo is hotter than most American made range ammo..shoot it thru a small gun and can feel the difference. Tula is only one that this applies to...but that is my felt experience..a chronograph may say different..but it definitely feels hotter to me.
Meme Commando Mike, true. If he wanted a real challenge, user the Sig, an RP9, or another jam-tastic masterpiece. It looks like three steel case was not there issue. . .
T Feltmat, there is a major difference in manufacturing quality standards depending on the manufacturer. In operations, project management, quality management, we track on all of these things and a lot of people think they're fixing quality issues but never really do. CZ gets rid of the initial "break-in-period" by operating actions in an automated fashion of all the pistols that come out of the factory. A lot of Manufacturers do not do this. Glock 19 from the Gen 4 batch notoriously had a break-in. That shouldn't make a lick of sense if they actually work the actions as they should have coming out of the factory. A lot of 1911 manufacturers claim a break-in period when in fact the equipment is just not ready to use yet. It is a cost cutting measure. They leave the last stages of making a quality product to the customer. Yes, the goal is reliability. But no, the techniques employed and the dedication to that objective are not the same.
I shoot steelcase all the time with no problems - pistol and rifle. I shoot steelcase 7.62x39 exclusively through my AR and have never had a problem. I did upgrade the firing pin and hammer spring to avoid light primer strikes.
I use to think that Tula Steel case would not stick as well. Had one firearm that I shot steel almost entirely, until he did not. It would continue to shoot any other ammo, but to this day it won't. Even after cleaning it, steel case would get stuck. And a steel case will not perform like brass. Many shooters that have shot a lot of steel will get that case that will get stuck, have to come home, oil the casing and use a dowel to get it out. Make no mistake, carbon will build up and try and put a empty steel case into a "Case Gauge". You will be lucky to force it in and again have to get a dowel to remove. it.
