Remington made a .25, a .30 and a .32 on a smaller diameter case to approximate the ballistics of the .25-35, .30-30, and .32 Special Winchester cartridges. These were used in Remington's Model 8/81 recoil operated self loaders, and Model 14/141 pump actions. The .35 Remington is the only one of the series still loaded, but it has a larger case. They were quite popular in the first half of the 20th Century, but faded away after WWII, as hunters became interested in newer, higher velocity cartridges. Unless you know someone who has one of these rifles, about the only place to sell them is to some obsolete ammo purveyor at a gun show. I once passed up a nice Model 141 because it was chambered for .32 Remington, and ammo was just not available.
