For Standard Velocity Only

[Bill Murphy]

I didn't reread all of the linked discussions, but I think possibly that the guns in question are short chambered at customer's request and marked "Standard Velocity" so that 2 3/4" shells would not be used in that particular gun. Just my opinion in the absence of solid information.

The two guns with these "FOR STANDARD VELOCITY ONLY" markings that I know the serial numbers for both date to 1929.

When Western Cartridge Co. added the 16-gauge to their progressive burning smokeless powder, high velocity, Super-X loads, they put it in the 2 9/16-inch FIELD shell. The first mention of the 16-gauge Super-X that I've found appears in a Western ad in the October 1922, National Sportsman.

While Remington and Peters followed Western's lead and put their 20-gauge progressive burning smokeless powder, high velocity, loads in 2 3/4-inch shells, Winchester, with a load of 2 1/2-inch chambered Model 12s in shooters hands, put their 20-gauge progressive burning smokeless powder, high velocity, loads up in both 2 1/2- and 2 3/4-inch cases.
