Hi, I have just tried priming some nickel plated federal .308 cases with federal primers. I am using the old style lee hand primer. I have used this to prime thousands of federal brass cases without fault. Whilst about 1 out of 4 primes ok, 3 out of 4 I am unable to prime as the primer pocket is too tight. comparing with some brass cases I can push a primer part way in by hand but not on the nickel cases so there is some size difference. Has anyone had this problem and can I get over it.
Any suggestions welcome.
