Hello everyone, let me start off by stating that I am not experienced whatsoever in the field of bullet casting. However, I do plan on launching the Missouri Bullet Co 255gr. Keith Bullet (BNH 18) out of my .454 Casull. Now I am wondering how fast I will be able to push it without causing leading or harming the forcing cone. Is there a rule of thumb that dictates which hardness fits which velocity? Thank you!
