Started having an interesting situation when de-priming .308 Winchester brass that I had shot cast boolits in this week. Using set of Lyman .308 Winchester dies (Been using them since 1980’s). I de-primed 11 cases and 9 of the 11 primers had the anvils fall out of the Primer Cup. These loads were not hot by any means and the anvils showed no pressure signs. But; the anvils were not staying in the primer cup after de-priming. This happens from time to time (maybe 1 or 2 in a couple hundred from my experience – but nothing like what I am seeing here.
These primers were from a couple of boxes of CCI #200 Large Rifle Primers that I bought when a few were available over the last 6 months (2 boxes of 100 was the maximum one could buy). They are not from my stash of primers from several years ago. I am wondering if anyone else has had similar experience. Seems that it could be a quality control issue in primer production, Of course; no telling when these particular primers were produced given our current availability challenges; and the resurrection of long forgotten stock forgotten in the back of storage rooms and warehouses.
Of course for most shooters this is a moot issue. As long as the Primer went BANG, and the accuracy was good and predictable, most would say no harm no foul. But; given the movement towards reloading primers in this era of perpetual shortages; this might be an issue trying to stuff those anvils back into a cup with a new primer mixture.
