I was going through my .45 ACP cases and while decapping them have found a few that were very hard to decap. I noticed that the ones that were hard were all Federal NT cases and they look as if they have crimped primers. Now I've only found about 4 of these in the last 1500 cases so its not a horrible loss if I just toss them. I do have a Dillon Swage that I could use on them but is it worth it?
