[QUOTE="Fiftydriver, post: 122607, member: 10"] B1G_BORE, When fireforming with bullets you need a certain amount of pressure to form the case properly. Most cartridge brass will deform at around 50,000 psi at the case shoulder. So to get this with a bullet you still need a decent load and your still burning 90 grains of powder and spending money on the bullets. For ecinomic and barrel life reasons, I recommend fireforming with corn meal once the barrel is broken in. For my Allen Magnums they have a limited barrel life anyway so why waste it forming cases when you do not have to. Kirby Allen(50) [/QUOTE]
