What is the point of having a 24-gauge sleeved to something else? Leave it for someone who actually wants to play in the 24-gauge pool.

Before The Great War, our ammo company catalogs list the 24-gauge shells, after WW-I the catalogs I see don't offer 24-gauge ammo but the companies occasionally made a run of 24-gauge shells.

The 1918-19 The Remington Arms Union Metallic Cartridge Co., Inc. catalog shows the 24-gauge offered in both their NEW CLUB black powder shells and NITRO CLUB shells with both bulk smokeless and dense smokeless powders --

Back in the day the 20-gauge was offered with both 3/4- and 7/8-ounce of shot, the 24-gauge had 3/4 ounce of shot and the 28-gauge had 5/8-ounce of shot. The 28-gauge finally got a 3/4-ounce high velocity, progressive burning smokeless powder, load in 1932.
