Home Forums Reloading Bullet Casting PB or GC?

HawkI is correct. Gas cutting happens where the bullet contacts the barrel/grooves/lands and not at the base. Here is a recovered 440 grain Lee casting that I powder-coated and tested without a gas check. The base and all the way up the gas check shank have the PC still in tact but you can see gas-cutting after that. PC is tough but not Magnum tough.
