I have a new 10P .308 that has fired 65 rounds. Yesterday it started not seating the case fully, it will not even start to close. The bolt will close without a round, but will not close even on a fully sized empty case.
I have been hand loading Lapua cases, Matchking 168g., IMR 4064, Wolf primers.
Hornaday OAL guage with a Sinclair comparator measures 2.127. I'm loading at 2.112 for now.
I tried some PMC Bronze and had the same issue.
I hope its just something stupid that I'm missing.
Any suggestions ya'll can offer would be appreciated.
