So another application for this could be if you have someone that is noise sensitive around you. I don't think she liked guns because she never shot anything while she was there. Sent from my Inspire 4G using FirearmsTalkĮdit: there was also a girl at the range with her boyfriend that said she enjoyed the sub loads too because they didn't make her jump. If you want more details on this load just say so. Subsonic ammunition is ammo that moves slower than the speed of sound, about 1100 feet per second. I only buy 300blk ammo from Gorrilla for hunting, especially the subsonic rounds. My gal really liked the noise level and the fun she got from it. This is a good load that I would suggest to anyone looking to small game hunt with an AR, or if you have a recoil sensitive shooter that you want to start out small. Many AR-15’s will only handle an 80 grain 223 bullet, limiting energy at subsonic velocities compared with a 200-230 grain 30 cal bullet in a 300 Blackout. This is the most deadly 77gr Subsonic ammunition on the market. If hunting deer with 223 was legal in my area (it’s not), I’d be running heavier, harder bullets to reduce the chance of splashing out energy on impact with a hard bone. Beck Ammunition Silent Operator series is engineered to run at Subsonic Velocities (just below the speed of sound) and to be shot with a sound suppressor. Heck, the 55gr 5.56mm load only has about 2.5 more bullet drop at 500 yards than the 7.62x39mm at 400 yards. 223 Subsonic round available for hunting or defense work. As you can see, all of the 5.56x45mm loads have a significantly higher velocity and much flatter trajectory than the 7.62×39. I have plenty of 223, 6.5 grendel 22 WMR, 6.5 creed and other popular caliber rifles, SBR’s and PCC’s that I can suppress but you still get the crack of the round. 223 is great for competitions, home defense, varminting, and plinking.

For crimping what I did was set the taper crimp on my die for a slight crimp on the trimmed brass, then I left it there for the untrimmed. This data is for Hornady and Barnes factory ammo and a 200 yard zero. 300 blk is great for CQB and tactical uses, and also for hunting small game and hogs. The second I didn't trim the cases because it is so much faster that way. Both used 55g FMJs from winchester and 3.9g of trailboss.
