I clean my brass in a walnut shell dry tumble or a stainless steel rotary tumble. For the ammo I plan to use up in the short term, under 3 months there is no problem. However the ammo I want to store long term I would like to keep it shiny. Personal thing. I would also like something that would seal around the primer and bullet, so moisture doesn't get inside. I have some .257 Roberts ammo that was reloaded back in the 70's, shoot great, but is down right ugly. Has any one tried vacuum bagging there ammo for long term storage??
