Decided to shoot up some partial boxes of reloaded ammo yesterday and had a problem I've not seen before.
First off I had 29 rounds of 348Winchester with 250gr cast bullets. I had shot 21 rds of thyis box last fall, no problem. Yesterday I could not close the action completely on any of the rounds.
Then with my Winchester BB in 375Win same problem with some jacked bullet reloads. Again these same loads worked great a year ago.
In both instances a moderate taper crimp had been used. i am assuming that omehow the bullets have ?? move4d forward in the cases, exceeding the proper OAL .When measured they are not excessively long and measure the same length as noted when loaded 1 and 2 years ago.
The Winchester 71 is well worn and is cleaned/bure scrubbed after every use. The Winchester 94 BB is as new. It has at most had 200rds though it. Again cleaned after evry use.
I plan to pull all the bullets, resize and reload.
Any ideas as to what I may be missing here?
