I'm starting to load 300 blackout and looking for the best bullet weight, powder type/grains for sub sonic suppressed. I'm running a 9.5" Rainier barrel and an Octaine 45 suppressor if that makes any difference. Any tips or load data is appreciated.

I stumbled on some info that I thought would be helpful, that I wanted to pass on. I did not see similar info posted anywhere on Brian Enos forums. I wasn't sure exactly what forum to post this, since it covers bolts and ammo, and suppressors, but ... I have a couple of Ruger 10/22's, both suppressed. I have been playing around with a bunch of different subsonic ammo. The cheapest and easiest to get (at least for me) is CCI Quiet. It is "as seem in the movies" quiet. But, it won't cycle the bolt. Then I found that Volquarten makes a FireFly bolt that is designed to work with the CCI Quiet ammo. Today, it runs about $200. It works like a champ -- as good as advertised. Volquartsen rep emailed me that they do not recommend standard velocity with their bolt. After I bought a pair of FireFlys, I stumbled on Norma Tac-22 ammo. It is also subsonic, and it will cycle the bolt of the standard 10/22. The Norma runs about 1100fps while the CCI is only 700fps. The Norma is more flat shooting. Currently, Midway sells both. Norma $50/500 and CCI $35/500 I also tried both on a Glock 17 fitted with a Tactical Solutions TSG-22, .22lr conversion. Again, the CCI would not cycle it while the Norma worked fine. Sorry for a sort of rambling post, but, here's the bottom line: If you want to shoot suppressed .22lr: - CCI Quiets are the quietest and cheapest but won't cycle. - Volquartsen Firefly works great with the CCI quiet, but, not recommended with standard velocity and it's $200 - Norma Tac-22 is subsonic, shoots a bit better, just a bit louder than CCI, and is $15/500 more money, but, it will cycle the bolt on 10/22 and Tac Sol .22 Glock conversions. So, that's what I learned with about $600 and a bit of screwing around.

I'm dreaming of a .300 BO SBR with a nice can on it. I don't know that much about piecing them together so I thought I'd ask all of you. Is .300 BO built off a .223 platform or a .300, or .308? (yeah, told you I didn't know much.) What should I know about ammo when it comes to home defense Vs hunting? Buffer, BCG considerations? Who makes a good barrel and how much does that matter on an 8"-10.5" barrel? Speaking of, is there an optimal barrel length and twist rate? What else am I not thinking of? Thanks!
