I've not done any further shooting with it but I had another idea. Maybe I didn't get the case lube off good on some cases and the bolt thrust is higher causing my action to stick and not the cases. I will clean the remainder of that batch with solvent to be sure they are clean. I normally wipe my cases with a damp rag or spit on each one and wipe instead of tumbling them.
The simplest answer is usually the right answer. I hope it's that simple.
