Shooting Bullseye competition in late 60's & 70's, in custon 38 spl revolvers and Jim Clark 45's, the signal to discard a case was longitudinal splits. After repeated resizings and firings, the brass is work-hardened and eventually splits. You may have a combination of brittle (work-hardened or whatever term you want to use) brass and an oversize chamber, but my money's on brittle brass.
Indeed. Starting to look like lawyers' discourse...The brass discussion sort of went over the river and through the woods.
