First, thank you for your videos and the quality content. Second, I recently purchased a couple boxes of Federal 50gr "varmint & predator" jhp. • I trust your channel. •I couldn't find much other than a water jug test. •It would be greatly appreciated to see it tested out of a 16in 1:8 into gel. Thank you for your time, Merry Christmas, -K
I personally know Randy Brooks, who was the owner of Barnes at the time Bin Laden was taken. He told me that Bin Laden was taken with something loaded by Barnes. He did not specify to me if it was the 77 gr load, but I assume it was.
I've ran 100 rounds through a 14.7 FN upper and I was getting 2400ish FPS and groups between .75 - 1.25". I had no issues scoring repeat hits on a 10" plate at 500 yards.
seems wrong at first because usually with my 14.5 I get around 2,850 with M193 or around 2,750 with M855 depending, and then you see these numbers and your like... 2,450 tops??? but then you hear about the accuracy and the bucking of wind etc. and realize that you sacrifice some velocity for great accuracy and also the energy upon impact is there 💯 Also hearing you using your FN 14.7 and hitting 8" plates at 500 with these..... yeah if I had an ammo can full I would definitely NOT be against loading the mags up and zeroing in for this basically MK262 but half the price if even available
@@shadyp-zv3uf lower velocity should be expected with a 77 over a 55. it literally weights half as much more and has a better BC. Also a 55 grain is .243G1 vs 77grain 350G1 BC. At longer range, the 77 will carry more velocity than the 55. M855 is not accurate... shits like 2-3 Moa. At 500 yards the 55 grain bullet is around 1300fps, at 500 yards the 77 grain is around 1425. And 77's are generally, but not always more accurate. IMO 77>55!!!!
Edit: I've since tested this ammo again, and it's all over the place from one lot to another. I tested 6 different types of ammo today, inluding this AAC 77gr SMK, out of a 18" BA SPR barrel, 1:8 twist, gassed/tuned with a low-mass bolt carrier/buffer/spring setup, Riflespeed AGB, etc. Did 5-shot groups of each, four times each, in rotating order, for a total of 20 rounds of each time 6 different loads, so a total sample of 120 rounds. Relatively calm, 64 degrees. In order of most accurate to least accurate average of four 5-shot groups each: AAC 77gr SMK: 0.676" AAC 77gr Sierra TMK: 0.740" Hornady Frontier 75gr BTHP: 0.934" Hornady Black 75gr BTHP: 0.969" AAC Sabre 75gr Black Tip: 1.272" AAC 77gr OTM: 1.317" The sun was getting low and messing with my chrono, so I gave up on it after my first series of shots, but oddly the SMK, TMK, and 75gr Sabre Black Tips all came in right at the advertised 2700 fps. I guess PSA chronos these out of an 18" barrel? Whats more interesting is how consistent the SD was. What's the most disappointing is the most expensive loading in the group, the Hornady Black 75's... poorest groups, however YMMV for your barrel. If I negated one flier out of 20 of the more affordable Frontier 75gr BTHP's, those were very close to the TMK's in accuracy. I didnt have any Black Hills Mk262 Mod 1-C to try today, but from experience I think it would have matched or beaten the AAC 77gr SMK's... but the AAC is half the price, and that's an interesting conversation to have when we're talking about a 0.2" or less MOA difference. EDIT: I've settled in on SMK loads from IMI. Their "Razorcore" proves to be the most consistent, higher velocity than most heavies from others, accurate. Not as hot as Black Hills, but more than most. I recommend either over AAC.
Great info! I wonder what would make AAC’s in-house 77gr OTM bullet less accurate than the Sierra MatchKing bullet considering the rest of both cartridges are made and loaded by AAC (ie presumably the same brass, primers, powder charge, etc.)-?
@SkepticalHippo R15 and Varget seem to be the most popular. I've used both and don't have an answer as to what is better, but I favor Varget simply because I have lots of Varget loads worked already.
PSA Nitride 16" mid-length, geissele SD-E, SOLGW BCG, Vortex Strike King 1x8...less than 1.25" MOA with 60 y/o eyes and AAC 77gr. HPBT Sierra MK. COULDN'T BE HAPPIER! THANK YOU MRGUNSNGEAR!!! 😁😁😁👍👍👍✌✌✌
@steveguse4481 in LC brass, you can't find it anymore because the powers that be shut it down. I have 1400 rds of it left and I'm just sitting on it at this point.
@@billydanzz ikr? Everyone with a functioning neuron knew what the op meant but I guess some people just need to feel important at the expense of others.
AAC also makes a great 110 grain 300 BLK round. I've been using it for a few months now and it groups quite well. PSA has really stepped up their game.
I put together a 20" AR upper using a FN barrel 1/7 twist. I used the same aac 77gr OTM to deer hunt with this year I dropped the first two doe in they're tracks. The third and fourth doe I dropped them with head shot's between 100 & 150yds. This ammo is almost as accurate as my hand loads. Oh and it does a lot of damage when you hit deer in the boiler maker.
@@TheInfantry98 why not? It's the original barrel length for 5.56. 5.56 performs the best out of a 20" barrel. It's not unwieldy, you only really need shorter barrel lengths if you're clearing buildings or using a suppressor. For a longer distance build or to hunt with it's a great choice.
@@TheInfantry98 why not I did it because I can. Makes perfect sense to me and that's all that matters. I'll be hunting elk and caribou with it next year.
@@brazzy1467 Elk with a 5.56? Hmmm that's pretty ballsy, not sure I'd be comfortable with doing that myself. Tbh not even sure about the legality of that. A lot of people were concerned about 6.5CM being not enough for Elk, although it's proven to be fine. But that has significantly more juice behind it than even the hottest 5.56 loads.
Buffman R.A.N.G.E. did it with 7.5" up to 22" and it was slightly lower velocity (70 fts lower than advertised for his conditions) vs IMI Razorcore and Magtech. Still an accurate loading, well worth the price, well in my opinion. Thanks for the video Mrgunsngear! Need to pick up more of this ammo.
Keep in mind, PSA (AAC) is currently having 2 separate 77gr in their lineup. 77gr OTM (Open Tip Match), and 77gr that specifically loaded with the 77gr SMK (Sierra Match King). The SMK tends to be more expensive than the other OTM.
@@fog8969 There’re couple vids of the PSA guy who shoots this round out to 800 yards. I guess as the 77gr SMK too popular and somewhat sacred, PSA wanted to make their own version at a more affordable price, which I really appreciate.
@@sebastiantran1266 Thanks I saw the vid the PSA guy did but at that time didn't know they had 2 different rounds. Checking invoice now I see that the few boxes I bought to test are the SMK.

Hey, whenever I try ammo I'm often looking at. I was shooting a 77 grain hollow point from my PSA 16 inch barrel at 200 yards. I was so impressed at how and how close and tight well my groups were. I've had best luck with a 69 grain but the 77 seems to make a big difference for me. I'll go out and do it again to double-check it but I was so impressed with it. My barrel is 1 and 1/7 twist and lighter bullets don't seem to do very well for me. I appreciate the delivery and presentation of your program. Thank you so much.
You're right.. way more instances of issues due to less penetration, where as issues involving over penetration are rare as hens teeth. Professional training will put to rest any concern one might have regarding an "over penetrating" round. Especially in a rifle I want to be able to shoot through shit.
My daughter just got her 1st deer w/ a 556 hornady 75gr core lokt. It dumped him instantly, double lung shot. It took him a minute to expire but he dropped instantly. No blood at all on the outside of the body, entrance or exit. Did good damage on the inside though. Good fighting rifle, does the job. but it isnt a 30 cal of course, 30 cal does the job without exception, in every way. Or any of the intermediate cartridges.
The Winchester 77gr BTHP Match rounds are comparable and my 20" 1:8 twist *loooooves* that round. That barrel also loves the 64gr .223 Deer Season XP round, but that's for another time. While the 77gr isn't my go-to PD load, my 16" 1:8 twist also does quite well with it.
Great review. No extraneous fluff. On too many channels I litterly have to STOP & Read the description because the "Host" isn't even remotely addressing the subject I clicked on !! Thanks for keeping it straight & with a sense of humor !
I don't have any experience with the Sierra load, but as it is legal to hunt with .224 caliber centerfires in my state, I have done some hunting with the 75 gr Hornady OTM. When I got my Colt 6960, I was interested in deciding between a few different loads for home defense. As hunting licenses are cheaper than ballistics gel, I took a couple deer with three different load; the 5.56 loaded 75 gr Hornady OTM, and two different 62 gr loads, the 62 gr Barnes Vor Tex and the 62 gr Federal Fusion MSR. All deer were shot within 100 yards, typically about half that distance. No deer required more than one shot or went more than 60 yards after the shot. So all rounds worked fine when given enough velocity and proper shot placement. From a purely hunting standpoint, the Barnes TSX was the clear winner. It performed great and had good enough penetration that I even popped a nice doe through the onside shoulder in a quartering to shot. The Barnes was the only bullet tested that I would do this with. The 62 gr MSR had the best combination of linear penetration and tissue upset, and is what I went with for my home defense load. The 75 gr Hornady OTM performed fine, fragmenting reliably, but as with the SMKs in this test, seemed to veer off unpredictably. I couldn't deny the deer died quickly, so it was hard to call the bullet performance a failure, but it also was the least confidence inspiring. I think for standard infantry, police, or home defense work where most engagements are close, I would prefer a good bonded JSP, like the Fusion MSR, Gold Dot, or Federal FBI T3 Tactical Bonded. The Mk 262 or similar does seem to provide the best range for the 5.56, so it would be, and is, the obvious choice for DMR setups like the Mk 12.
@Milkman3572000 16 inch chrome lined 7 twist with mid length gas system. I tend to think the 16 inch is the most practical for a civilian, but I do have a soft spot for 20 inch guns in general and the M16A4 specifically. I don't get into many gunfights inside an elevator and never approved of turning rifles into SMGs, so I don't see much use from the really short tubes.
@@mehicanbls1526 you can also build a house with a 8oz hammer, but it doesn't make it the best tool for every job. Don't get me wrong, I bet your rifles quite capable and I'm not one to begrudge a mans choices. For me and my surroundings the 20'' offers what I feel is the best option. Merry Christmas!
I got a few different loads of 77gr OTM. From Winchester, SSA, PMC to Magtech. The best was SSA when they used SMK rounds. Magtech is my preferred load. Winchester is a bit under powered. PMC is the absolute worst 77gr ammo I've shot to date. Velocity put of an 18" barrel was 200-300fps below advertised velocity. I've killed hogs with 77gr ammo a few years ago. One hog I killed, probably weighed at least 80lbs, was hit behind the shoulder at a distance of 10 to 15 yards. Dropped like a rock. Haven't done any hunting lately, but for 5.56mm ammo, Magtech is my go to load. It preforms great and really close to advertised velocity. I would recommend buying them whenever you see then. I'll have to get a few boxes of AAC's load and do my own testing.
I'll be checking this out when it's back in stock. Until then, I have had VERY GOOD results with the IMI Razor Core 77gr (MK262 mod 1 clone). Very accurate as well, sub MOA at 100 yds.
I'm sitting here with my 11.5 hd gun with a Lancer full of 77gr Razor Core. I don't claim it's the "best" hd load, but I'm confident it will do the job. And I have a reasonable stack of it without breaking the bank.
Why would you shoot 77 grain Razor Core out of an 11.5" SBR type AR ? It's long range ammo. You're wasting it. Run some Winchester extreme SP varmit ammo or Hornady SBR ammo for home defense with that 11.5". I say this as a former SOF guy. Don't waste your 77 grain on a home defense set up. PLEASE !!
@@rascalmatt6713 I'll take your word that you're an SOF guy but you seem uninformed about the performance of 77gr from short barrels. 77gr has good terminal performance at a wide range of velocities. This includes long range (where velocities have fallen to 2000fps or lower) and close range from short barrels. 77otm is not barrier blind and that is it's only real shortcoming. You use what you prefer of course, but if you are going to offer advice, please take the time to be informed.
@@carolinausedmachinery Enough to know that at close range or "home defense" distances aka "CQB" distances, 55 and 62 grain is good enough to drop someone or blow their brain out of the back of their skull and have it slide across the floor. Most carry what they are issued,which at the time was M855 green tips. If you are a DMR or Designated Marksmen, you could potentially have 77 grain OTM's. On the civilian side, 77 grain OTM's are EXPENSIVE. And again, at close range inside a home, 55 and 62 grain will work just fine but if i'm concerned about "over penetration" and hitting someone in another room unintentionally, i'll roll with some kind of soft point HD or hunting round that fragments upon impact. A big part of being in SOF is thinking for yourself. "Unconventional Warfare". If you can do the basic research and think for yourself, you should be able to figure it out on your own. At the end of the day, run whatever you want. If you don't want to think about it or just want to follow a trend, the crowd, MrGunsngear etc. That's on you. I can assure you however, that i am much more informed on all of this stuff to a much higher degree than you or 99.9% of anyone else in this video thread. I have a ridiculous amount of ballistic data on my laptop. I have hit milk jugs at 1,000 yards in 3 shots or less using IMI 77 grain ammo out of my own SPR rifles. I have hit soda cans in 4 shots or less at 760 yards with the same set up. ALl in the windy mountains of Utah. I shoot multiple times a week and compete in PRS on the side. I don't comment in here to brag. That would be fucking pointless. I comment to help those of you out who can critically think and take good advice.
@@rascalmatt6713 You absolutely have a point about typical home defense distances. The likelihood of having to blast someone beyond 50 yards is extremely low. I do keep Frontier 75gr OTMs in my 11.5" (I believe this load uses Hornady's 75gr TAP bullet), but in my 13.9" I use a 62gr hollow point load that Winchester made for the FBI several years ago. Despite saying .223 on the box, it's got a 5.56 powder load. Allegedly the bullet is barrier blind. Whatever the case may be, that bullet does gnarly stuff to whatever it hits. I bought 2K rounds of it back during the corona madness because it was relatively inexpensive.
The 77gr otm is very preferred in the sbr of around the 11.5" barrel. Works extremely well ive been told and is preferable for special operators deployment of their sbr.
I would love to see you run this load through the rifle you put together for the 2-3-2020 video titled “Ultimate AR-15 Designated Marksman DMR Rifle Build” both the gel and accuracy if you still have it.
Probably the second or third most accurate bullet across a variety of rifles, and it would probably do well out of a short barrel for self defense. I found better loads for terminal effect on deer, but those weren’t scientific tests and when I hunted with 5.56 it was with 20” barrels.
Been loving all the AAC ammo. Not gonna lie it's not the absolute cheapest, but it feels like the best bang for buck value and their XTP clones are pretty spicy and at the right price.
I've been waiting for someone to do this since AAC released the round. IMI has been my goto round for my short barreled AR pistols for years. (Bought not so cheap but stacked it deep.). If the AAC can match IMI for accuracy and velocity, I'll be switching.
AFAIK, it's the same bullet, at basically the same speed, so I'd expect the same performance(ish). As long as it cycles properly, I'm sure it's terminal effect is GTG. FWIW, I bought a small stack of IMI RC 77g before the chaos of the last few years and have it loaded as my first few important magazines.
This is a very accurate round. I get surprisingly repeatable results using it. And I'm getting the results I was looking for in a factory load ammo..... specifically out of a 13.9" build I'm fine tuning, but has ran flawlessly in my other builds as well and really brings the potential out of my 11.5"... Nothing is going to perform like a meticulously perfected hand load, but they took this stuff seriously when they set out to manufacture it for us. You can't beat it for the price IMHO. If you're looking for an affordable, accurate, repeatable factory load (especially in your shorty's).....this is for you. Nice Review Mike. Appreciate ya 👍
I ‘sighted’ in with this at 100 yards on a 8” gong, then went straight to 400 yards with impacts on a 12” gong way more than I expected with a 3X and red dot, and just givin’r. 16” stainless Hanson midlength on an otherwise all Aero AR. 150 rounds with zero hiccups
Could you imagine just being able to call your buddy and ask how different rounds affect "bipedal threats" 😅. God bless our troops and veterans! They keep up safe _up range,_ then keep us entertained (& educated) when get they get home. 👌👍
I appreciate you, Brother, and your channel. Good channel variety of subject matter that matters or is of value and interest. Keep up the good work. Best of luck with your channel. I wish you well, you and yours.
These little things are hammers! I do have a bunch, and they're quite accurate at 30 yards... which is all I'm zeroed for, as I intend to use these for home defense. Thanks!!
Would love to see this test with a 20" barrel. I have a theory that this round out of a 20" with a 1/7 twist is the ideal set-up for "stopping power". To get a round this heavy moving at that velocity one would think would be ideal for doing "damage".
BTHP have always been one of my favorites. I've been using 77g TMK as my go too for a good while . This AAC ammo look absolutely solid. Hopefully it's at decent price point and in STOCK. Black Hills 77g TMK , MK262 or any other awesome Black Hills loads are almost never in STOCK these days .
Just ordered 200 rounds a couple days ago and received today. At .85 cents per round shipped if it anywhere near the accuracy of the 75 Hornady frontier I shoot(1moa) it’s an easy swap.
I would never rely on an AR. MANY do. If I had to settle for an AR...This would be my load. I have used tons of 75 gr 5.56. Love that for accuracy. I'm sure this is awesome.
Honestly I prefer the 75 grain hornady BTHP or the 75 grain speer "bonded soft point". Slightly higher velocity and almost no difference in accuracy. I am getting amazing results with CFE 223 and both of the bullets with a cci 450 primers. Getting about 2100 out of 7.5 inch, and just over 2700 out of a 16 inch.
Thanks for the content! I been testing out the AAC's 125gr 300 Blackout, and it been good for the range. I picked up their 110gr V-MAX in hopes it runs good as well.
Before the COVID boom I was using the 75gr 556 Hornady because it was so cheap compared to all 77 but it seems prices have changed between the two sizes.
Picked up a case of AAC 69gr OTM. 200 fps faster. Stunningly consistent and accurate at 500 yards from a 16" Palmetto State upper. Someone told me they're using FN barrels
I'm looking forward to comparing this to my BH Mk262 mod 1. As of date no ammo matches the accuracy of Black Hills 77g on my Mk 12. IMI razor core is no match for Mk 262 Mod 1 ammo in both of my guns but it does shoot well. Your mileage may vary depending on what your barrel likes.
What's the velocity comparison of BH to IMI? Buffman did a chronograph of IMI and AAC 77gr. Have to check and see if he did a BH, but I think AAC appears to be quite a bit lower in velocity compared to IMI.
I shoot competitively and served in SOF. I shoot a LOT of long range. For me, as much as i hate to admit it, IMI 77 grain Razor Core OTM's have been faster and more accurate out of my 18" Noveske SPR and DDM4V11Pro than BH 77 grain OTM's. In fact, my screen icon is a 0.4" five shot group of IMI 77 grain OTM's out of my Noveske, which i hit a milk jug at 1,000 yards with in 3 shots and hit a soda can at 760 yards in 4 shots. Just my personal experience with both rounds out of those two popular platforms.
@@rascalmatt6713 Oh I believe you. It amazes me how barrels like certain brands or weights over others. I don't understand it and it's over my head but it's real.
That round works quite well at killing 100-200lb hogs, they rarely make it more than a few dozen feet before they fall over dead, this is out of a 14.5" barrel and ranges from 20-100yds.
@@whenpigsdie6103mine is about 85, I use a 16" barrel suppressed, also use 60gr SP loaded at about 2900fps, shot placement is key, rarely do they make it another few steps on the run and tumble over a couple time. I've had about 20 drop without taking a step, all from 50-215lb hogs
I tested a box of this on Saturday. New build with an 18” Ballistic Advantage barrel. Got a 2” group at 100 yds. Only about 50 rd of 55g Fuji through the barrel. I was slightly disappointed but will test more.
Nothing wrong with the ammo, I’m sure, but this really highlights just how much you’re giving up by going down to a 10.5” barrel. 5.56 just needs that velocity.
Yea, pretty much what dude said above me. Same goes for bonded soft points. The Speer Gold Dot in 223 in 55/62/75 g loadings all perform phenomenally as far as terminal ballistics go anywhere from 1480 to 3k+ fps.
So glad to see you reviewing Palmetto States ammo I've been wondering whether Amo is any good. I've also been curious about thee stuff from Ammo Inc, especially there are 110 V-Max max 300 blockout in upload.
Check out Mead Ammunition 77gr BTHP. Made in Nebraska from people that have been making ammo for almost 50 years, and it is a great price. I shot a .4MOA group with my 18" AR15. I know it is hard to believe, but you can watch my review of the ammo on my channel (not trying to shamelessly plug myself). I promise their ammo is some of the best I have ever shot, and it is very cheap (I paid $130 for 200 rounds) compared to other 77gr 5.56 ammo. I am not knocking AAC, it is great ammo as well, just carries a heavier price tag. Great video as always Mrgunsngear.
If you add additional tape to the opposite end of block 1 and the entry of block 2 the gel will not DANCE as much during entry and expansion. Currently the penetration/expansion is causing the exit end of the gel to move during the expansion process.
I see a lot of people talking about the .300 blackout claiming is superior. Personally, I believe 77 grain sierra match kings out of my suppressed MK18 and MK12 to be perfect for what I need. I’ve shot a couple 300 blackouts, It is versatile but I find it’s more an elite hybrid smg/rifle. Super cool, but I’m not willing to drop the extra dough on a new setup.
I love your content. Keep up the great work. Don't be afraid to keep us informed on important current events involving the 2nd amendment or corruption in the DOJ. Have a Merry Christmas and thank you for your service.
Love those tests. shows nicely why 5.56 is called an intermediate cartridge with 10mm like ft-lb on target out of the SBR. Listening to the other side you would think it is a cruise missile 😂 Out of a 16’ my 308 puts 100 grain more bullet on target at the same speeds.
Decent accuracy, but several people on arfcom have reported flattened primers (with subpar velocity, so no overpressure), dented brass, poorly machined extractor grooves, no sealant being used on primers or bullets, and no crimp on bullets.
I’d definitely prefer sealed primers and bullet, but that’s going to raise the cost. I’m sure PSA is going for the more affordable route with this. They’re working on the dented brass.
The 77gr bullet weight was/is a bona-fide game changer, and IMO, the best extant threat stopper. Thanks for the gel data! -PS: Mike, wth optic are you using in this vid?
Once you go 69gr or higher, it's hard to go back to 62gr or 55gr. You can easily get round after round at 500 yards with a 77gr and actually hear it hit steel.
Seems on par with other Mk262 loadings. IIRC from the 18" Mk12 SPR it gets around 2750 FPS. You'd have to get a larger sample size and compare the Extreme Spread and Standard Deviations between loads to see witch one is more constant, as well as which is more accurate in your rifle.
Sample sizes used by guntubers are always woefully small and inadequate, You really need sample sizes of at least 30 rounds of each to adequately estimate variation and statistically significant differences.
Thank you for this video. I have been frustrated trying to find 77 OTM for my carbine. It performs better than any other load but has been unobtainable. Hopefully, AAC will produce enough 😃
@@raystephens2078 Yep. Got some. Haven't tried it yet. Just saw an interview with a Hornady ballistician on Vortex channel, said something negative about hollow point can't remember what. Will link it later.

Defensive load means close range,and that in my mind you want velocity, and that is why 55 grain bullet is king and Winchester does good enough for me in accuracy in old CL 1x9 rock river on bench and bags. That shirt of yours, you should think about it double tap!
I have shot hand loads, and factory 77 grn match, can't remember brand, been a while. I used My early Bushmaster 20" barrel at service rifle competitions and mine stabilized at 200 and 300 yards. Rated at 1:9 twist, either I'm lucky and got one with a little more twist, or the 20" barrel extra length helps.
I have 20 rounds of 5.56 hpbt 77gr matchking need to shoot some to see where it hits compared to aim, gonna hurt to shoot, it was stupid expensive back in 2020 when I bought it.
Off topic , but I couldn't help but notice that your a right eye dominant shooter , shooting a left hand eject Stag Arms A/R -15 , I own that exact rifle , but I am a left eye dominant shooter and enjoy not having the brass and blow back gas thrown in my face on every trigger pull !
My magtech 77gr OTM is 2500 fps out of my 11.5" and 2700 fps through my 16". Makes me glad all my barrels are polygonal rifled for that extra bit of accuracy and velocity. Either your barrels are bad or it's an anemic load. Typically polygonal rifled barrels get an extra 30-50 fps compared to button and 5R rifling.
Definitely wouldn’t want to do a hostage situation with that ammo considering how it changes directions in the test media. A bonded bullet would be a better idea.
