The Problem: I've primed several hundred cases (.308 face, Large Rifle Primer) when I encountered a problem putting a case in the jaws. Thought perhaps an out of spec case head, but measured OK. Disassembled, refitted the jaws, reinstalled the priming cup holder, and now it strikes the platform the jaws rest on.
The Solution: Cleaned, lubed primer cup holder shaft, removed jaws, and removed plate that holds the Co-ax rods and the case holding jaws. Realigned platform using primer centering tool, reassembled, and works perfectly. Even though plate fasteners were tight, the plate was slightly maligned.
Perhaps this will save someone cases and time.
