About thirty years ago I was shooting a lot of Doves with a 16-gauge 1928 vintage A.H. Fox Sterlingworth Ejector Field chambered 2 7/16 inch intended for 2 9/16 inch shells. I was using those wonderful compression formed 16-gauge 2 3/4 inch Winchester/Western Dove & Quail loads that the folks at Olin provided us for a few years. I didn't see any problems shooting those shells in the gun, but it really ironed the crimp memory out of those cases. When I shot them in my 1909 vintage Remington Arms Co. KE-Grade with full 2 9/16 inch chambers and more modern 2 3/4 inch chambered pumps and autos the crimp memory was great and to this day I get better reloads from the hulls shot in longer chambers then those originally shot in that Fox.

Indeed sir. I've used 2 3/4 inch hulls/cartridges in 12, 16, 20 and 28 bore guns for years. Thousands upon thousands of rounds, too. Velocities are around 1150 fps. NEVER a problem. And the hulls come out looking totally normal.

Consider that the forcing cone accommodates an extra 1/8 to 1/4 inch of case material with no issues...
