2/11/2024 0 Comments Benchmark powder 5.56That said I did not find any load data at all for 223 and Lever. It wasn't a matter of me pushing anything 'hard'. If you can help me find some other real world data for Lever and 75 grain bullets I will be more than glad to re-test it. I like the buffer zone for error especially when I go to mass production. I almost NEVER go beyond max on any of my loads for any rifle. The average from I think 20 shots was something like 2458 (including one outlier that had a lower velocity). I ran multiple strings of TAC loads and the highest velocities using published data (not over) was 2481. Normally I go through several days of trial and error just to try and catch things I might have missed. Yesterday was the first day of testing so absolutely NOTHING is final. 2 grains that would have possibly matched the manufacturer's published average data using TAC. I guess it might, but on average I estimated a gain of 30-40 fps should I bump it up by. 1 grain of Lever would add 75 to 100 fps to average velocity and my estimation was no. Just eyeballing my non published load development with that powder I had to figure if another. But based on what I was seeing I knew I was getting pretty close even at 25.5 grains. Taking into account that my bullet was 75 grain I just did a rough guideline on it. In his video at around 25.6 grains (albeit using a 77 grain bullet) he ran into pressure signs in his rifle. That said I recalled a video from JRB where he attempted to clone some 77gr ammo so I was left using only a rough outline of where to possibly start. My basis for even buying it is that I can test it out in 6 ARC. Today's testing netted me a gain of 139 fps over what I previously had gotten.Īt this point I would be more than comfortable buying a few 8lb jugs of TAC and calling it good, but I still want to do some research before I do that.Ĭlick to expand.I went with PUBLISHED DATA. I think the charge weight with CFE 223 was 24.9 grains or something like that. The best I was able to get with CFE 2 fps. I could probably up the charge beyond published max but I tend to stay away from doing that.Ĭompared to the previous high water mark set by CFE 223 I made big improvements. A published max load of 24.1grains netted me a velocity of 2464 fps with everything else remaining the same. I could probably go up a little bit in charge weight but I didn't see the point, especially considering that there was no way it would catch up to TAC. 25.5 grains of Lever netted 2373 FPS with the 75 grain bullets. Given his bullets were 77 grain in that video. Johnny's reloading bench used Lever in a 223 video so I worked my way up to similar loads that he was using. Fortunately for me I can also use this powder in 6ARC. Leverevolution does not (as far as I know) have any 223 load data. This is the published max load on Hodgon's website. H335 produced 2312 FPS using a charge of 23 grains. I definitely want to try some more to see if I can get even better.īelow are the real world results out of MY gun, a 10.5" SBR shooting 75 grain Hornady bullets. This bullet, or Hornady GMX too, or Barnes TTSX, all those in 50 grains.they are not match bullets, so you can expect around 1.5-2 MOA, which is not an issue because a 10.5" AR15 is made for pretty much under 250 yards or so.īought several powders to test out. Molon did a good writeup on it, and everything he said is good. There is probably nothing better than this "overall" because its barrier blind too. Out of 20" barrel, you can do 3400 FPS in nato pressure. However, if you are not keen on 2300 FPS or something like that, then this is what you want, and its proven.ĥ0 grain Barnes TSX. It doesn't need high velocity to penetrate and do mega damage. I know what you want for your 10.5, if you want top tierĪny 77 grain OTM< like Berger will be top tier choice for any shorty.
