Now I’m curious what the actual 2 7/8” chamber lengths measure in the 1800’s era Parker and other Damascus barreled shotguns. I’m not talking about sticking a “pre marked” gunsmiths gauge in there. I’m talking about actual measurements from the forcing cone to the “barrel face” like I did. “More Modern” guns I would assume have longer chambers to compensate for the fold crimps. I did a quick Google and I think Remington came up with what they referred to as the star crimp(fold crimp) in 1939. I would assume guns from the 1939 and newer have longer chamber lengths( probably closer to 3” or more) to compensate for the extra half inch or so of the longer fold crimped hulls?

It does make sense to me that someone bored out my gun at one time because I forgot I had some all brass hulls. They didn’t fit at first because someone fired them in a 10 gauge canon but after getting them cut down and finally sized after hours of screwing around with two of them, they are just under 2 7/8” inches long. And that’s because I cut them short by accident. So I would assume the 1800s guns chambered for 2 7/8” ammo back from the same era are cut to 2 7/8” lengths and not longer because fold crimps weren’t invented back then yet.
