I am loading some once shot brass I picked up at the range and the head stamp reads "WCC90"....This stuff is a bear to prime. I have crushed and bent more of the primers than I have got seated. Have any of you had problems with this Winchester brass?

Sounds like the crimp in the pocket is causing you problems. They make tools to remove it; I just use a chamfer tool and a light twist to remove them myself.

It is truely amazing, this web site I mean. I can't imagine how much easier learning to load would have been if I had had access to this much knowledge when I started loading in the 60s.

Yup, wcc,(Winchester Cartridge Company), brass IS crimped. It is what winchest makes for military contracts. Either a primer pocket swager or crimp removal cutter is needed.

This is what I use for removing primer crimps.

I found the RCBS to NOT work well at all. It left some of the crimp in the pocket, so priming was difficult to do. This was for lake city military once fired.

But here's the RCBS if you want to try it.
