My 1930 vintage VH-Grade 0-frame 20-gauge has the 2 3/8 inch chambers intended for the 2 1/2 inch 20-gauge shells. Our ammunition manufacturers offered the 2 1/2 inch 20-gauge shells up to WW-II. For most of the manufacturers, the heaviest load they offered in the 2 1/2 inch 20-gauge shells was the 2 1/4 drams equiv. 7/8 ounce load. However, Winchester managed to stuff the 2 3/4 dram equiv. 1 ounce, progressive burning powder, load into the 2 1/2 inch shell, while all the other ammo makers only offered it in 2 3/4 inch or longer shells.
