I've looked & can't find any threads on this. I need some tips. I got some brass & steel shell casings last night. I noticed the steel casings have a small brass middle. How would I remove this? Or is it worth it? I tried a punch but all I do is knock the whole bullet and all out of my vise. If I squeeze the vice tighter then I can't get my punch through. Does anybody know a trick or am I wasting my time on such a small piece of brass?
