Default Military Brass Shotgun Shells

I was curious if anyone has any knowledge/experience with the old 12 gauge brass shotgun shells. What smokeless powder did the military use in these?

Check online for a copy of War Dept. Technical Manual #TM9-1990 "Small Arms Ammunition" dated 1947. Although it doesn't name a particular brand of powder, it does discuss smokeless powder to some degree as it relates to shotgun ammunition. It also shows that the late-war M19 brass shell used a 26 grain dense smokeless powder.

Nothing special or unique to the shotshell powder in brass case buckshot. Different powders could be used if velocity was met within pressure limits.

The unique thing in brass shell loading would be the wads. Thinner brass shells use a larger diameter wad column.

Factory ammunition did not normally use ''canister-grade'' powders available to handloaders.

And this is why Army Ammunition Data Sheets ARE NOT reloading data and do not reflect the actual powder charge in US military cartridges.

Powder types are often changed and amounts are adjusted as needed to meet spec. In “the sheets” all powder weights are in even grains (52.0). That alone tells you is isn’t a true load amount to meet velocity/pressures requirements.

The amounts in data sheets are just there for ordnance trainees to memorize for promotion boards, harrasment by superiors, etc.

I have a Small Arms TM 43-0001-27 that discusses brass shotgun shells just doesn’t list the powder used. Just says smokeless.

Please note to everyone I do not re-load shotgun shells. I was just curious if anyone knew the brand of powder used in these.

Not one single brand...a smokeless shotgun powder to meet velocity and pressure requirements.... could vary lot by lot, year by year, contract maker by contract maker.

There is no single brand used.
