Well, if you have an early Winchester Model 1885 Low-Wall rifle, for example.
There were a lot of cartridges in the .25 caliber family of similar performance, spanning the black powder to smokeless transition.
Some folks call them "rook" cartridges, intended for potting critters at no more than 100 yards. Examples include .25-20, .25-35, etc.
I even have a box of original .25-25 ammo, and it's kinda neat looking.
