After reforming a bunch of 30-06 brass, I loaded up and went to my club to fire-form the cases for my 7.65 Mauser.
Closing the bolt was tight but extracting the empty was easy. Empty cases chambered easily, but after full length sizing
it was again an effort to close the bolt [on the same empty case]
Case length was fine after sizing, so the question is: are the chamber dimensions different on a 91 compared with an 09 which Lyman
probably made their dies for ?
I've checked Olsen's book and everything else that I have but I can't find any info.
I guess the obvious answer is to neck size only in future, but it's an interesting mystery.
