Current Rifle Cartridges
.25-20 WCF or  .25-20 Winchester
Please Note: This is NOT the .25-20 Single Shot Cartridge.
The .25-20 WCF or .25-20 Winchester was introduced around 1893-95 by Winchester for the Winchester 1892
Lever-Action Rifle and later for the Remington Model 25 Pump-Action Rifle  Marlin Model 1894 CL Lever-Auction rifle,
Savage Model 23 Bolt-Action rifle, with others to follow.
The 25.20 is basically a .32-20 necked down from .32 caliber (.32") to .25 caliber to accept  (.257") bullets.
It was one of the first varmint cartridges to be introduced before the famous 22 Hornet or .218 Bee and was good out to
150 yard with various bullet weights. No almost obsolete today except for a special run from time to time.
