I'm setting up to start loading 300 Blackout. I've seen a few posts and videos on using pulled 147 gr. M80 ball projectiles with about 16.5 gr. of H-110 as a supersonic loading. I was at Cabelas flipping through several reloading manuals and could not find 147 gr. load data. My Hornady 10th edition manual doesn't include it either. I was wondering if anyone here is using this projectile to load 300 Blackout with success. Any feedback is appreciated. Thanks!
