Anyone Having Problems With Winchester Primers?

44mag444mag4 Member Posts: 47

I have trouble with Winchester large pistol primers not seating correct. Have a RCBS press and cannot get the primers seated correctly. They do not seat flush like they used to. Installed a new primer seater in the press with no help. Using Star-line, Winchester and Remington 45 Colt brass. All brass is once once fired. Cleaned the primer pockets, no help. It takes considerable pressure to get them seated to the point they will not jamb the cylinder. This happens in the two 45 cal revolvers I own. Anyone have any ideas? All help will be greatly appreciated.
