Recently began considering doing a 300 blackout build. My criteria is quiet and accurate to 100 yards. Pretty simple right? lol. I always wrote the 300 BO off as a fad and didn’t get it but a dedicated subsonic rig seems like the solution for what I’m looking for. The reason is I live in a neighborhood but we have lots that are 2 to 3 acres and we are surrounded by farm land. Recently some coyotes have been seen and actually killed a neighbors little yip yip dog. So I’m looking for something to use on them hence it has to be quiet. The neighbors actually requested I take them out, but I don’t want anyone to know when I actually do lol. I have a spare AR lower so I have the option to build one in that platform or I was thinking a Howa Mini bolt gun. Any thoughts or suggestions? Still haven’t decided what can to go with either. I also thought about getting a big bore PCP air rifle but not sure.
