Default Is this due to a bad chamber in the Krag that fired it?

I recently bought a bag of once fired 30-40 Krag brass from Bison brass. Every single piece was missing the neck angle. Once I ran it through the sizing die, it looked normal again. I am wondering if the brass looked like it did due to a chamber issue on the rifle firing it. I have shot many rounds through my Krag, and it has never looked like that. It has always looked like my resized brass.


From the bag on left, resized on right.


Two on left before sizing and two on right after.

Well: with old and particularly with rimmed cartridges, there are large variations in rifle chambers and sizing dies. They just don't care because the rim does the headspacing and what is in front of it doesn't matter, compared to a rimless case that needs a properly dimensioned shoulder. If you size your fired cases just enough to maintain contact with the shoulder, and you avoid hot loads, your cases will last. If you don't follow this advice, they won't. Your cases are fine, stop worrying and fire away. Good Shooting. ...

I suggest that after sizing, you measure the case length, and trim the neck back if necessary to correct length.

Just looking at the photos, I can see that the case mouth seems to have made contact with the rifling. Also, there seems to be a variation in length among the different cases shown.

I see only the remnants of the original crimp. Considering the typical long leade in 30-40 chambers, I think it impossible that the case could reach the rifling. However, cases should be trimmed to length..... Good Shooting. ...
