I've been shooting my first reloads. Lead bullets, BE powder, CCI 500 primers, out of a Lone Wolf barrel. I've noticed increased muzzle flash and the gun running "dirtier" than shooting factory ammo. I verify each case for signs of overpressure and do not see them (bulging primer, scratched case, excessive force by ejector). The load I'm using is conservative 125gr bullet, 1.14 OAL, 4.0 of BE. Am I missing something, or BE is considered "dirty"?
