32-20 WIN.

The 32-20 Winchester (aka 32 Winchester Center Fire, or 32 WCF) was Winchester’s original small game lever-action hunting rifle cartridge. It was a black powder round when it was introduced in 1882, although it is currently available with smokeless propellant. Expect a modern 32 WCF cartridge to propel its 100 grain bullet to a velocity of ~1,200 fps out of an 18 to 20” barrel.
