Redhawk 44 hit the nail on the head. It seems that the Rockchucker, the dies, or a combination of both are allowing enough "give" that the cases were not being adequately sized down. Even though all the cases were fired in the rifle for which they are being reloaded, it appears that the partial sizing stretched the case wall enough to put the brass out of specs for the chamber and the shortened stroke was not adequate to push back the shoulder. I kept adjusting the die down until I got a reliable and repeatable fit in the chamber. All of my mistakes aside, it seems this particular rifle (Howa Lightning) does have a very tight chamber after measuing some once-fired unsized brass. The expansion was almost negligible.

Thanks to all for the help.
