I pretty much exclusively use CCI 450 magnum primers, they have given me zero issues.
I have done some loads using diferent primers, Fed 205's, CCi 450's, CCI 400's and have used the WSR primers.
The only ones I used that gave me problems were the WSR, like you I had a very small amount that pierced. Your issue sounds identical to my experience. I would just stay away from them or your just going to be chasing your tail and waste a bunch of ammo and time using them.

If you can not see the tyranny of having a gun ban enforced by men with guns... Then you fail to understand why the second amendment was written in the first place.
