I picked up a piece of fired brass (30-30) at the range the other day. Whoever fired it was long gone, but I think it was likely a win 94. The primer had backed out a little indicating a "springy" action, and there was a slight bulge above the case head on one side, but no obvious signs of over pressure. The round appeared to be factory loaded (no die marks, etc.) The odd thing is it sure looks like rifling marks are evident on the case. They appear to have some twist and continue from the body of the case onto the neck, skipping the shoulder. They also appear to have been "pressed" into the case body above the web when the case expanded to fill the chamber upon firing, and seem consistent with the rifling style and pattern in this type of rifle. Anybody ever seen this? I always thought chambers were cut after the barrel had been rifled, so I don't see how this could happen. Just curious, there were several others lying around in the same caliber with the same markings, so it was not just one shell.

Thanks

I forgot to mention that the brass looked completely normal otherwise. Case head expansion looked normal for a 30-30, neck and shoulder were not blown out or blown forward. The brass also did not display the "fluted chamber" marks of an HK type chamber either... Posting this in Gunsmithing too

Have no idea but would like to see a pic.

I'll try to post a pic, prob early next week...
