I swore off CCI primers a while back. The cups were varying in size enough that some of them were sticking in the primer tubes for my Dillon press, measured cups varied by up to .008". They required a lot more force to seat, and there was no accuracy or velocity gain to continue using them.
I use Winchester and Federal now, no more sticking or any other problem. They seat nicely, cost about the same, and generally make life easier. I am glad some guys like the CCI's, that leaves more good primers on the shelf for me.
