The same load could be issued to road officers for low-key usage in non-supressed 14.5 and 16-in. Be nice if the round could penetrate a tire rim, too. 22lr subsonic out of the AR with conversion kit. This load would be mostly for euthanizing injured animals, prefer softpoint/hollowpoint. I also want to play with different bullets in the 69+ gr range.Ī heavier projectile version of the 22lr out of and AR that doesn't require a conversion kit, different magazine and the issues associated with 22lr fouling AR and can. I'd like to get it down to and average of 1050 fps (true subsonic level) with a SD of 10 so I am going to play with the powder and start working down in 2/10 increments. I have no idea on what it's max effective range would be but I'd say 200 yards would be a safe bet. Primer crack is less because of bolt staying closed. Filled with (10) 20-round boxes of Red Ops 223 Remington 56 Grain FMJBT Red Ops 223 Remington ammunition is made. About as loud as subsonic 22LR out of the AR w/can. How quiet is a silenced AR-15 with subsonic ammoIn the past. 223 bullets shot from a suppressed rifle.

These will not cycle the bolt (so single shot and manual rack) Many viewers have requested a sound test of subsonic. I shot these out of a AR15 w/ 1-7 twist 10.5" barrel / AAC can (these would be excellent on a suppressed bolt action. 223 subsonic.ĥ.2gr Trail Boss (fills case nicely - does not meter to well though *donut shaped powder) There has been a lot of chatter on Internet sites lately about centerfire loads that fire bullets at subsonic velocities.
Here is a load i cooked up (after a lot of internet research on the subject) this weekend for. These loads and others were shot with Trail Boss powder in an attempt to develop subsonic velocities (left to right).
