First, let me apologize if I posted in the wrong place - I'm a newbie here. We are cleaning out my in-laws estate and I came across something like 50 old .22lr rounds, and I mean OLD! Could be 60 years old or more! How can I safely dispose of them? Would it be safe to try to remove these rimfire bullets in an impact type bullet puller? If so, is there a way to make the powder harmless once removed? Didn't seem like a good idea to just toss 'em in the burn barrel...
