The heaviest 12-gauge smokeless powder loads offered by our North American ammunition manufacturers from the late 1890s to the early 1920s were 3 1/2 drams of bulk smokeless powders or 28-grains of dense smokeless powders such as Infallible or Ballistite. From the 1905 UMC catalog --

These loads have been reported to be higher pressure than SAAMI specs which came into being circa 1925.

In the early 1920s our ammo companies introduced progressive burning powder, high velocity loads, Western Cartridge Co.'s Super-X leading the way in 1922. Progressive burning smokeless powder moved out the 1 1/4-ounce 12-gauge load at higher velocity with lower pressure than the old bulk and dense smokeless powder loads. The progressive burning powders also allowed the upping of the payload in the 3-inch 12-gauge shell to 1 3/8-ounce at acceptable pressure levels.

Researcher,

Looking at the price. How many rounds are they selling for almost $60. Even at a flat that would be $6 per box which was the price I was paying in the early 70's.

Have a smith check the wall thickness of the barrels where the chambers were lengthened. I have a heavy barreled pin gun that someone lengthened out to 3". I have only shot 2 3/4 loads out of it but it really kills the birds. The chokes remain full and full. The barrels are still plenty thick. My main concern with shooting 3" shells out of it would be the stock. I would like to keep it in one piece

Tamid, I believe the shot shells were sold in crates of 1000 at that time. If so then a flat would run $15, a box $1.50

The prices are per thousand. Two cases. People were stronger forty and more years ago and shot shells came in cases of 500 shells, 20 boxes. Now we can only lift 250 shells, 10-boxes in a flat.

Call and ask them to send you some more pictures especially the inside of the barrels. That company can measure the chamber lengths again for you too.

67galaxie. I may do that but I'm thinking I going another way since I want a double for a waterfowler and a gun like that one, I think, deserves more gentle care than it might get. I may do as you say and call and see what they say. Thanks

It's pretty used. If the chambers have been lengthened, the lop is right and you like the gun then I would shoot 2 3/4 bismuth out of it and make ducks hate me
