I bought a 300 blackout 10.5" radical upper along with a pistol brace. It has an 8 twist. I'm putting it on an 80%, so the sbr thing won't be an issue.
After reading lots here on the blackout, here's what I think I know.
1. 8 twist isn't fast enough for the Lee boat tail.
2. Pc is the way to go. I have smokes clear and black.
3. The alloy needs to be fairly hard not because of velocity, but pressure.
4. Noe moulds tend to be too big in the nose for an ar15.
5. Gc bullets without the check should be ok with pc. I'm not real sure I got that right.
How am I doing so far?
Forgot to add, I won't be using a suppressor.
