Do you think there is any chance the case mouth could “crimp” closed slightly rather than stopping forward bolt movement? False reading?dellet wrote: ↑Tue Apr 16, 2019 12:27 am Have you tried to chamber an empty case?
I would be inclined to try a couple things. If an empty case will not chamber, I would trim maybe .005” and try again until the bolt closes. A stripped bolt would be best. This will give an idea of how much brass is in there.
If it closes on an empty, then you know it’s farther forward and hanging up on the bulllet. Then I would compare the length the bullet used to hit the lands at and how much shorter it is now.
With that information it might change my next step, that may or may not be suitable to print on an open forum
Maybe pay attention to the diameter of the case mouth before and after.
