I am looking to reload some subsonic .223 for my SBR with use of a Ranger 2 can. I have read that subsonic .223 is not much better than 22 LR but I would like a round that is quite. I do not care if it does not cycle the action.

I found several people asking for reload information on the internet, but no real data. The best info I have seen so far is this old thread http://m4carbine.net/showthread.php?...=subsonic+.223

Does anyone have any new info for load data that will be fairly silent?

One last question. 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 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. I know not to believe everything I read, but I just want to make sure.

I've only reloaded for bolt actions, never for my AR and certainly not subsonic. Any Advice?
