subsonic 5.56

[falcor]

Hello,

I have been reloading for a while now and I really enjoy it, but am looking for some new challanges. I own a gemtech suppressor for my AR-15 and would like to tinker with making a sub-sonic round. I like how quiet the suppressor is, just would like to loose the sonic boom... and heck I am needing some new challange. What I don't want to do is destroy or damage a perfectly good AR-15, etc.

Other then dies, and all the standard reloading hardware, what do I need to start this project? E.g. Anyone have a formula they want to share so I can start somewhere? I assume that a 55gr bullet is going to be too light, and I probably need to use handgun or shotgun powder... but I am not too sure where to start. Any help would be appreciated! Thanks!

kinda of busy to explain things to you, but your barking up the wrong tree with using hangun or shotgun powder..

especially shotgun powder... I garuntee that wont do you a bit of good :)

Notice how shotgun shells have wads? ;)

If you still need info go to accuratepowder site and work your way to the .223 listings and subsonic load data is at the very bottom. Keep in mind they have been trying this since mac cans came out and they were putting them on the m16s. Basically they found a subsonic round will not cycle the action but you can shoot them single shot. Most can warranties are voided by shooting 223 subsonic but I think that Engles ballistic research stuff is suppose to be ok in factory cans. Hope this helps.
