Like other lever action rifles, the Winchester Model 250 was capable of feeding and shooting all types of standard .22 caliber rimfire ammunition like 22 Long Rifle, 22 Shorts, and 22 Longs. Owners of the rifle in several online forums often talk about using this firearm with 22 Colibri ammo or 22 rat shot as a great home pest elimination tool.
