Use in combo w/ .31 pilot on .303 British cases

By Dorman T. on Nov 25, 2019
I have had longer case life on brass when fire forming in the old war horse first, due to intentionally generous military chamber size . Then run full sizing die down to newly established neck base and shoulder before trimming and light chamferring. This process will prevent the constant reblowing of the case and prevent early case separation. Newly chambered rifles are conventionally full or neck sized according to preference. Safe annealing of the cases periodically also extends case life, as does loading to pressures in "oldphart" moderation. Hope this helps.
