Hello all, Might I get some input from Ya'll? I'm enjoying the reading material I've found while working half way around the world and I'm leaning towards a bolt action 300 blackout (no can) on my next R&R home. 1. How much louder is it compared to 9mm carbine or so? 2. Since I'm not getting a can. What weight bullets are preferred for accuracy and economy? I will be reloading some. (a hobby I dont get much time for lately). Thanks, and thanks for a great forum.
