I have never used a GC bullet before. I'm thinking about a lead bullet with my 450 bushmaster and would like to use the Lee 454-300-rf. I would be powder coating them so I'm curious if I would need the GC?
I was pushing 230hp at 2100-2200 so I imagine the 300gr would be under 2000pfs. The PC powder is from smoke so I know it's good stuff I've only ever run it to. 1200-1300 in my 9mm though so just wanted to check and see what you guys say.
