I just ran into a problem that I have never seen after having made some 25K to 35K reloads. I was running some Blazer and Federal 45 Auto brass with small pistol primers through my Hornady AP Press and had a problem. Several of the primer cup tore and only on the Federal brass. I had to stop and size the Brass on my Rock chucker.
Has anyone seen anything like this. I gonna try my RCBS Primer pocket uniformer on my case prep. I don't care about a few pieces of brass but it really puts a hamper on a progressive press when you have to stop and clear the problem brass.
Thanks
