This is to be the accepted norm I would think. By reducing the power, you pretty much eliminate the ability of your gun to cycle. Even with 75 grain bullets, just how reliable will the results be in a serious situation? Also, bullets intended to fly at 2500 fps and above may be hard to stabilize at 1050fps etc, causing baffle strikes. You're taking a screaming-fast round and reducing the powder charge to below the speed of your average off-the-shelf bulk 22LR. I'm no "Operator"-just a guy enjoying his hobby playing with guns. It's a lot of fun getting the gun as quiet as possible and could be useful in pest elimination, but that's about it.
#SUBSONIC 223 LOADS FORUM FULL#
I'm not saying it's impossible to get an AR15 to cycle with subs, but it would take some extensive mods/experimentation that would render it useless with full power ammo IMO.įor my uses, the subsonic ammo in an AR15 is not much more than a novelty item. The bullet hitting a target at 50 yds is the loudest sound. This gives my AR a sound similar to a Daisy BB gun. The bolt carrier appears to move about 1/2" and then closes back. Since I don't have an adjustable gas block, the action will attempt to cycle just barely. Any keyholing at all and that load does not get any more consideration. Only after several have passed that test do I attach the suppressor. At the muzzle, about 10 or 15 feet and the 3rd at about 20 yds or so. I set up 3 sheets of cardboard at different ranges and shoot all three at once to test stability. Need to test the rounds on cardboard at as close a range as possible (like 6") to insure the bullets are stable when exiting the barrel. I have not done any accuracy testing yet. This with CCI #41 primers and mixed brass.
#SUBSONIC 223 LOADS FORUM CRACK#
4.6 gr broke the sound barrier and I had the telltale crack on about 50% of the rounds. The load I settled on was 4.4gr Trail Boss. I have worked up my first 223 sub load using 55gr FMJ bullets. Try the round with your can off to make sure it's stable before silencing it. I've only reloaded for bolt actions, never for my AR and certainly not subsonic. I know not to believe everything I read, but I just want to make sure. The reason I ask is because I read on the internet that too little powder in the case can cause a pressure spike in the gun and blow it up or the bullet may not stabilize. Can too little of a powder load be harmful for your gun or silencer? Blow up the gun or cause baffle strikes because too slow of speed to stabilize the bullet. The best info I have seen so far is this old thread ĭoes anyone have any new info for load data that will be fairly silent? I found several people asking for reload information on the internet, but no real data. I do not care if it does not cycle the action. 223 is not much better than 22 LR but I would like a round that is quite. 223 for my SBR with use of a Ranger 2 can. It is intended ONLY for barrels up to 14½".it occasionally sticks in the barrel of a 16" carbine.I am looking to reload some subsonic. This uses the same 100grn bullet but uses 8grns of powder and a small foam filler. Powder (25grns) looks like Vihavouri.ĮS also produce a round that will not cycle the action- different folks like different things. Accuracy is adequate for it's intended mission out to 100m or so.īullet is filled with Tungsten carbide- so not cheep. 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. It works as advertised within a narrow window.
