I got some old ammo last week, and it came with some old reloads. I've taken the ammunition apart, tossed the powder (no idea what brand/type it was) and polished the brass for reuse. Now I have a bucket of bullets I'd like to reuse for plinking. Some are 38 caliber lead, some are copper jacketed 30 caliber. I though about tumbling them, but it seems the lead would royally trash my tumbler. Thoughts? Ideas?
