You did check the headspace,right?
From all of the sources I’ve rifled through during this adventure, the consensus was this:
99.999999 times out of a hundred, the headspacing will be fine. Even if it isn’t, what am I going to do about it? Take the barrel off, get a reamer and re-cut the chamber? Nope.
I’m just going to do this the old-fashioned way.
Gonna load a cartridge into the chamber and pull the trigger.
