Put the pipe down and slowly back away Johnny. 😂😂😂 You’ve been spoiled with an exceptionally accurate barrel. Anything sub moa is considered excellent in the AR platform. 1/2 groups are extraordinary and unusual in anything but purpose built precision rifles. Being disappointed with .66 and .72 groups with LVR powder is.........ridiculous. Someone had to tell you, lol.
I just did a workup with LVR and ended up with almost the exact same results... 77 smk 25.3 gr in LC brass. 0.74" 5 shot groups at 2730 avg (14.5 SD) in an 18" barrel. Have also found LVR likes 175smk in 308 win. really a hidden gem of a powder. Absolutely exceptional.
@@rdsii64 i used Gordons Reloading tool for workups because i couldnt find any data. Started with 41 grain and worked up. Hit my target velocity(2650) at 45.6 grains with no pressure signs.
I use LVR In 5.56, 6.5g, and 308. If you stick with the powder you'll notice your groups go wonky at colder temperatures. A magnum primer cleans them back up
I could be wrong but the staked primers are from the M855A1 Enhanced Performance Round which require a different crimp style for the extreme pressures of that round.
Just found this old one from you. I figure if you can use lever for some hunting loads 223, 6mm arc, 6.5 Grendel, 7.62 x 39 and your 30-30 that’s pretty versatile.
Hey Johnny... Two questions. First, when will we see an H335 video for the 77 grain? Next, what powder that you've tested so far would be best for the 77 grain bullet in a 16" barrel? AR Comp I imagine? I'm chasing mostly velocity, I can do with 1 MOA.
Thanks man. Congratulations again on the elk hunt and the 262 clone have me thoroughly inspired to load some up. I have not used any in a quite a while.
Getting back into reloading after a 30 year break! And that was almost exclusively pistol reloading. So, I apologize if this is a silly question..... Wouldn't it be better to choose a slightly "bigger" group with the lowest SD, rather than choosing the "tightest" group, that actually has one of the highest SD? At only 100 yds is one thing but, out at distance, say 6-800 yds. Isnt that high SD going to kill the groups?
If the bullet can be loaded to mag length in an AR10 or an AR15 you can use RL15 to good effect. You can drive 55 to 77 grain grain bullets to NATO spec velocities with RL15. You can also drive 150 to 175 grain 30 caliber bullets in the AR10 to proper velocities with the same powder. Powders like RL15 CFE223, TAC, AA2520 are very flexible in this regard. Also, because they are all ball powders, they will meter from progressive presses like the Dillon XL650 and the Hornady Lock-n-load progressive very well.
You haven’t talked about making dummy rounds for your various 223 bullets. This would save much time, just thought I would mention it. My complements to you, I reload and have learned much from you, it is possible to teach an old dog new tricks.
I switch bullets so much that I don't generally get to make use of dummy rounds! This series would definitely be an exception. I think I'll load one up and start using it. Thanks for the reminder! Should save me a bit of time.
My load: 2000MR 25.6 grains = 2740fps out a Windham Weaponry Varmint mod WW-15 barrel 20 inches (Compass Lake Engineering) chamber gives me a noticeably different recoil over ANY other powders. The 2000MR recoil is a HARD thump compared the typical pop from other powders
Very good video!! If you ever get time, I’d love to see a comparison video of different bullet seating methods. I was watching an old Sierra video with David tubb. He always seated the bullets by turning the case 4-5 times while seating his bullets and claimed it helped with runout. It would be interesting to see if that improves accuracy vs seating the bullet in one long stroke
I love those Tubbs videos. Packed full of great information. I sometimes do the turn-the-case-while-seating method but don't really have a good way to test it. It's not something that is going to make enough difference for you to see consistently in 5 shot groups at 100 yards. His experience of tens of thousands of rounds in competition tells me it's probably useful!
Is that a chamber chiller? Sorry didn't hear you mention it. If so do you notice a major difference in cool down time between groups? Thanks for 28 minutes outta my day that I can enjoy! Lol
I was thinking on your video part 1 the 2000MR might be the powder they originally used. I disassembled some BH 223 myself and believe it has the same powder as the 556 and also found after dissasembly of the barnes 556 vortx, it uses the same powder as the BH 223. Have you dialed in which powder is the BH factory powder? Is it the 2520 you originally thought or is the 2000mr a consideration? May I ask what is your conclusion? Thanks Johnny @Johnny’s Reloading Bench
Enjoyed this one Johnny, two powders I would've never tried. Both with imo excellent results....especially the 2000. Wow, it's an excellent grouper across a wide charge range. Hard to find that sometimes. Looks to be a great all around load at the least. Looking forward to the follow-up on that powder. I would also vote for H4895 as it is an extreme powder and always gives me excellent results in any bullet weight.
Hey Johnny. I love the channel full of good information especially on the mark 262 series very interested to see what your velocities were again with Varget as I retrieved much higher velocities with an 18-inch barrel in Lake City brass,coco 200 primers. Two of my loads we're 24 grains of Varget 2811 ft per second standard deviation of 10 and extreme spread of 13 with no pressure signs. This is an 18 inch barrel with a 1 in 7 twist and it's a Wylie chamber. Keep up the good work love watching the videos!
Hey johnny. Im new at loading .223. I bought a lb of reloader 10x by alliant and I got 77 grain smk with federal small rifle primers..i cant find any info on loading that recipe. Cant you give me any insight on what I should try
Think you will have fun with the 75gr Hornady. I'm running those in 3 Gun with 22.8gr AR-Comp seated to 2.260" with CCI #400, LC Brass and getting 2770 in an 18" AR Stoner barrel. Easily shoots Sub MOA and flies extremely flat. Looking forward to that video.
Thank you brother have some leverevolution and going to use this data is is kinda funny they don't have data in the hornady manual or on hodgdon sight either
Go to a dollar general or dollar tree and get the two sheets for $1 poster board. Don't put your dots on the glossy side unless you want a sheen when the sun hits it.
@@duckslayer11000 I ended up just ordering 14 x 19 cardstock from Amazon traced a set of lines out for 2 rows of 5 targets each and then photocopied em works great!
HEY JOHNNY THE PRIMER POCKETS ARE WEARING OUT PREMATURLY BECAUSE YOU GRIND THE POCKETS INSTEAD OF SWAGING, WE RAN INTO THE SAME THING TILL WE WENT TO SWAGING INSTEAD OF USING A TRIMMING OR GRINDING METHOD.
I do not ream the primer pockets. The RCBS Military Crimp remover tool only removes the crimp area. You underestimate the extremely high pressure loads we're shooting in this series. Normal pressure is generally 10+ reloads with LC no problem.
I get the high pressure with the series, but think about it when you grind/ scrape with your method you are removing brass = removing support for the primer pocket that removed brass was the previous support for the primer. if you swage the pocket it takes the crimp and puts it back into its support role / restores the integrity of the case . if the brass is removed the support is compromised. We are both missing the point that with these pressures in this series is exactly why there are crimps in the first place. :) Thanks again Bro for all you do, we salute you Sir.
I'm interested to see how those 73 grain ELDs work for you. I shoot high power and tried 200 of them and couldn't get them to group worth a damn out of my 1:7 WOA 20" barrel. Went back to my 77 gr SMK & Nosler CC. I tried the 75 gr too seated about .008 off the lands and was not impressed with those either.
I had a .358 Win that I ended up selling, unfortunately. Anyhow - I bought some LVR because it was the only thingI could find at the time. And using 200gr Barnes Bullets , It shot groups that my .308 envied . And it wasn't a fluke because I was setting up my scope using 4 shot groups and the target showed 3 groups of 4 shots all (almost) touching. ane group High/Left, 2nd group High, 3rd group bullseye. at 100 yd. Not BSing
And that 2000 Mr that's strange I've heard of some screaming velocity out of that powder in 223 and 308 ice been wanting to try it out in 308 with some 150gr Sierra bullets for a hunting load
I haven't seen anyone claim that, but I'll give them a sniff and see how they compare. They are all right next to one another on the burn rate chart. 748/blc2/cfe223/lvr
I have gotten many more reloads using LC brass than what you seem to have gotten. I use CCI small rifle primers and have never had a problem with loose primers. Try some of those CCI primers in that “old” LC brass.
I have also gotten many reloads from LC brass (10+ with normal pressure loads). Those were CCI primers I was popping out by hand. You underestimate the extremely high pressures we're shooting in this series.
I think you need to rerun your load data. Yes the mk12 is 18” barrel and the mk262 was designed specifically for it.. however you are forgetting that it’s a DI system. Burn rates and charges are going to be slightly off cause the gas port is bleeding off pressure which to me explains why you are having some velocity issues. IMO it would be better to select powder for a 90+ % burn for the length of the gas system length not the barrel length. You went about this as if you were shooting a bolt action not a DI. You are loosing pressure between port and muzzle. If I’m right you’re entire powder selection is a little too slow on the burn and you need something hotter.
Love your work and your generally analytical nature. I don’t think you leave anything on the table. I have found that logarithmic trend lines are a better fit for velocity prediction in various barrel lengths. I know you like to use linear trend lines when graphing but give a logarithmic one a try sometime. To that end, I x-y graphed your velocities vs charge weight of 2000-MR, inserted a logarithmic trend line (which was the best fit vs a linear one), and had it give me the equation for the trend line. This equation gives me an estimate of 26.53 grains for 2757 f/s. FYI, you might blow your face off.
Does anyone else seem to have far more problems trying to seat Federal primers in 1st pocket reamed brass? CCIs just seem to work much better on newly reamed Lake City for me.
What is best expanding/exploding bullet? For (against) fox, to be sure that bullet doesn't continues after hit. Vmax Hornady40 grn was very bad. Nosler was far better exploding. So other's better in experience?
Hey those 73gr. ELD's look like they would make some good butt kickers. I've wanted to try them because I think that's the heaviest I can go with a 1 in 9 twist. Interested to see how they do.
I bought a box of factory 73 ELD's that shot horrible with terrible SD's, like I'm talking 40... This was out of an 18" Ballistic Advantage .223 Wylde barrel. Might have just been a bad batch but I expected a lot more from Hornady.
Sbjr31 Good to know. I'll have to try some and see how they do. I've heard BTHP's will stabilize but the tipped mach kings are to long. Thanks for the info will try
Sig _nified Thanks for the info but I haven't bought a box of factory ammo in 20 years. If I do try them I will be reloading. Good to know not to waste my money on the factory stuff.
Yeah this stuff is a hidden gem really. It loves heavy projectile 223 and 308 win. works well in 7.62x54r, 303brit, 30-06, and of course 30-30. I really haven't found a rifle cartridge in my inventory i couldn't get decent results with it. Its become my go to rifle powder to stock.
@@kidddogbites It's a little dirty, from what I have seen, but the soot is fine and not gritty. Just needs a good wipe after shooting. I think it's the same formula as CFE223, but without the cleaning agent
@@iamnitrox Thats a popular misconception that its the same as CFE223 without the copper cleaner. It is indeed a different formula. The same myth went around about CFE223 being the same thing as BL-C(2) when cfe223 first came out. Just because they're both ball powders close to eachother on the burn chart doesn't mean they're the same thing. I run into pressure faster with CFE than i do LVR. Can usually get higher velocities with the LVR. Your mileage may vary though.
I reload steel case ak with boxer drill the flash and I peen the crimp hole so it’ll squeeze the primer in the over size hole!! So Maby u don’t have too have too throw that brass away. ? I’d peen it and shoot it a few more loads.
