Has cycled reliably in all the rifles I have tried it in- 1960's vintage M16, Current M4, HK 416 and ruger Mini 14.īullet (on the new stuff) weighs 100grns (old was 127grn) which is marginal on stability. Out of 16" barrels like our test HK 416's.it is often just supersonic (1180fps) but a few civi spec 16 barrels it stays just below the speed of sound. It is designed to be subsonic in a mil spec 14½" barrel- it is. I messed with it, then moved on to other projects.It works as advertised within a narrow window. To load subsonic (under 1100 fps) you will be hard pressed to get enough gas to cycle the action. Also 22.0 Benchmark and 77 SMK or 69 SMK come in a close 2nd.

I read some were loading them backwards eliminating the stability issue. It is far better to reduce a load from 1200fps to 1050 than to start out at 600fps and accidently blow your gun up. 223 if you have 8 twist or faster give trailboss a try, i think around 3-4grains, sounds silly but it really different powder. Seems a flat based spitzer you might get some more weight before it gets unstable, vs a boat tail. Tracers are going to be long for their weight so probably not work. That is not absolute on weight, it would depend on the bullet and how its made. V-Max Advertisement Varget 27.0 3344 2. Start higher then 4.5 and reduce your load accordingly till you get subsonic.

Re: subsonic 223 that cycles I was making some 223 reduced loads a while back that would cycle my Ar15. 223 and 50-55gr bullets I would start at 4gr N310 and reduce the load until you're subsonic / happy with. I have safely tested up to 6gr N310, so no safety concerns in the unlikely event that I double charge a case. I use 3gr N310 with an 83gr cast bullet (about 980fps) in my 6x45 (6mm-223).
