221.R Pistol Unsuppre ssed CC I Standard Ruger 10/22. I'm thinking of making an upper with the gas port about 3" downstream of the chamber (like the 300 blk) so that the pressure is high enough to cycle with a 7 grain load of H110. 111 dB dB us SILENCER SILENCER Remington zoo vrR 308 Remington 810 12 Shotgun Unsuppressed 9mm Walther P22. My subsonic 223 does not of course cycle the bolt on the AR-15. Standard small rifle primers work very well on little cases like 300 blackout or the 223. I always use mag primers for any subsonic load requiring large rifle primers like 308. I load to 1050 fps so that I'm good to go with any temps you might see in the continental USA. Use of a chronograph is not optional, it is required to ensure that you are at least 1000 fps so the bullet doesn't yaw and cause baffle strikes and less than 1100 fps so you are not supersonic on a hot day. Has anyone cast their own 224 bullets and used them for subsonics. The margin between supersonic and a squib was almost very narrow.
I tried some 55 gn PC 224 cast bullets using trail boss. I wish it was, as I like to fiddle with loads and find the optimum. Magnum primers are better than standard as they are more consistent. I dabbled lightly in some subsonic 223 Rem, as reloading 22LR isnt really an option. It works, doesn’t cycle the rifle but it’s quiet. I tried 3.1 grains of Titegroup under a Nosler 69. 223: I looked on the Hogden site and found a subsonic load: 3.1 grains of Titegroup and a 55 grain bullet. Blackfork is trying to develop subsonic loads for his. The cartridges are loaded to the crimping groove for the fmj, to 2.26" for the 70 grain bullets. 223, Ammunition, ar-15, handloading, rifles, Subsonic, suppresor.
My brother wants cheap ammo, so he uses the bulk bullets.įor my NM AR-15, 1-8 twist I use the Speer 70 grain bullet with 7 grains of H110 or 3.5 grains of Bullseye. Everything I shoot is reloads other than 22lr, 12 gauge, 7.62x39 and 7.52x54.įor a Mossberg MVP, 1-9 twist it is a 55 fmj with 3 grains of Bullseye.
