Thread: 300 blackout and titegroup?

Titegroup should work and it'll sure be quiet. Can't help you with starting charge though. A word of caution with it, it's a very fast pistol powder and the onset of pressure signs will happen very quickly, so work up in only very small increments. It's also very dense meaning it will be possible to double, triple, maybe quadruple charge the case by mistake and cause some serious damage to gun and even shooter.

Red Dot is a more sensible choice because it's very bulky. It's potent enough that you could still get into trouble, but a double charge would be immediately obvious. It's fast powder too. You'd probably need a pro grade decibel meter to tell the difference.
