I just found about 30 rounds of old .357 Magnum JHP ammo that's corroded. I tried to disassemble the rounds using a Quinetics bullet puller, but the bullets won't come out of the brass. I kept banging on one round until the lead actually came out of its jacket, but the jacket stayed in the brass! I don't want to take a chance shooting the ammo, so I need some advice. How can I safely unload the components?
