Reloading for the 1891 Carcano, Part 2

[Patrick Chadwick]

As far as I can tell from the photos:
No. 1 is presumably the one you described, where the primer fell out.
No. 2 shows cratering.
No. 3 seems OK, but the depression appears to be rather wide. Is your firing pin going too far forwards?

I suggest that you measure the neck diameter of the extracted cases as accurately as you can. Then measure the neck diameter of a case loaded with one of the ".2675" bullets. If the second measurement is not at least couple of thou less than the first, then maybe the loaded case was so tight that the neck was effectively jamming in the chamber. That would indeed cause very high pressures, as the neck cannot expand to release the bullet.
