Guys, I have a 300RUM that just came back from the smith a week ago.
Ran 40 rds. through it with no issues.
Then had several random cases stick in the chamber in the next 20.
I checked several fired cases to determine fired headspace at 2.471 +/-.001. I set up my sizing die to resize to 2.468 and loaded a bit more.
Had a couple more random cases stick...... went through a bunch of brass i had sized in the same pass and found that some of them were measuring 2.471, 2.470 after sizing in the same setup.
Had a couple shellholders so I took .002 off one and seem to be getting consistent sizing to 2.468 +/-.001.
Think this will be a good solution to this issue?
From what I'm seeing it looks to be chambered pretty snug but I can't seem to find a datum line measurement anywhere to confirm. Any thoughts/suggestions?
