What presses and dies are you using and general equipment recommendations.

Now that I've got the HDY dies reset to the HDY shell holder, I took the loads apart and using a 30 cal bullet comparator I measured the difference in length at the neck/shoulder junction and the ones that wouldn't chamber were about 0.010" longer than the ones I had just sized.
Once the cases are fire-formed to my chamber I can back off the full-length sizing of the brass a thou or two...
