Hi Folks!

I'm reloading some .223/5.56 Lake City brass on an RCBS progressive press (Pro 2000 with APS), and I've had problems with primers going in crooked, sometimes at a 90 degree angle.

Question ...

- Could this be caused by my failure to properly ream out (swage?) the primer pockets? (I'm using an RCBS primer pocket uniformer, but perhaps some roughness remains. I've been cautious about grinding the pocket too long.)

- Or could this be caused by some problem with the RCBS priming system? (However, the primer _looks_ centered in the shell holder.)

- Or both?

Many thanks!
Dave
