with the extra back pressure of the can and the wide open gas position i wouldn't think there would be a problem. it's my understanding that a suppressor ADDS backpressure and thus needs less gas to run a standard loading
Aussie be careful when using subsonic i have had 3 yes 3 squibbed barrels from using engle ballistics ammo in my Ar's i wont use it again i even gave 200 rounds away . The last time i went to a event set i up 10 lbs of tannerite, pulled out my SPR i went to show a fellow how quite it was. That was it ! first round squibbed screwed up the whole day. I'm all the way up in SC with no more center fire rifles just pistol cal sub guns the tannerite is still there :duh: if you don't have a spotter confirm the round left the barrel check ! it cost me 250 to save a $400 barrel at Cole's gunsmith last month
In my experience if you're looking at sub-sonic ammo, stay with the pistol calibers as thay are better performers at that low velocity. What would you rather be hit by, 180 - 200 grains of .40/.45 travelling at 1100 fps, or 120 grains or whatever travelling at 1100 fps? Depending on humidity etc... 1130 fps is the speed of sound at sea level. At that speed a pistol hollowpoint will function, a rifle round will simply drill a hole and not do much else.
I think .22 will happen, right after they get the new stock done, get 6.5 and x39, the XCR-M, the trigger, and of course the PDW. From talking to Alex the other day the XCR-m shouldn't take too long once they get it started as most parts are common between it and the -L. At least that is what I took from the conversation.
I find more and more people wanting to shoot .22 as the cost of ammo continues to rise. I already have 1 .22 can and will get another one, they are just too fun to shoot.
