Been hand loading since 1985. I have never had a safety kind of problem.
At the range yesterday we had a 22-250 case refuse to extract.
Bolt lift was sticky, as in a 16 ounce hammer smack was necessary.
Then the brass had be knocked out of the bolt face.
I was sweating what I would see. The bolt face looks okay but additional review is upcoming.
The primer blowout was located at the deepest point of the firing pin into the primer.
The case body was not scarred. Case head had some burning.
I unloaded 10 of the remaining 22-250 rounds. I measured each to ogive and OAL. Weighed each charge, checked case dimensions, weighed the bullets.
Nothing was out of spec. Brass that had never been loaded was checked for all dimensions. Nothing. Triple checked the powder, it was okay.
Then the thought came I had a squib and it was not detected. If that is the case I would expect a failed barrel, material in the bore, something. So far, I see nothing. I am going to check more closely later.
Some details:
I have loaded and shot this recipe for at least 4 years
43 grains Hodgdon Superformance powder
FC brass brand new never fired
Federal 210M primer
Nosler 60 gr partition
Browning A-Bolt Medallion
Any ideas? Have I overlooked something?
