check out the 300 blackout forum.the 300blk is the fasted growing gun/ caliber in America today.it is sammi approved, every co. can make stuff for it, and fwiw, it was made primarily as a supersonic round, not sub. not that aac doesnt want to make $ from the sale of 762sdn6s.it makes a great deer gun or pig gun out of the standard ar. it is becoming the go-to gun for piggy hunters in texas. it is a great caliber, but you have to use the right caliber for the right job. coyote hunting at distance, unless standing still, would probably require somthing different. although the remington loaded barnes ttsx goes at about 2300fps. and ammo is being sold by lots of places right now and more later. freedom group will make sure of that!! oh did you know freedom group is remington,aac,bushmaster...........
