See DealThe 25 Winchester Super Short Magnum is a relatively new center fire rifle cartridge developed in partnership with Browning Arms Company and Winchester ammunition. It made its debut and was introduced to the shooting public in 2004. The newer .257″ short magnum cartridge was originally chambered in Winchester’s Model 70 bolt action rifle. It is a commercial cartridge based on the 404 Jeffery cartridge case, shortening and necking down to .257″ caliber and sharpening the shoulder angle to 30 degrees. The 25

WSSM cartridge has more than enough case capacity for its intended dual purpose use.
The 25 WSSM factory loadings show a velocity of 3,470 feet per second for an 85 grain varmint round and 3,060 feet per second for a 115 grain bullet for deer hunting. This translates to very low recoil for the shooter with plenty of bullet energy at the 700 yard mark for varmints and predators and the 400 yard mark to harvest any white-tailed deer size animal. The 25 WSSM cartridge achieves its useful purpose as a very flat shooting varmint cartridge and as an excellent deer cartridge as the .25″ caliber is a time-proven caliber for deer size animals.
The 25 WSSM cartridge is a well thought out cartridge as Winchester is no stranger in .25″ caliber cartridge development. Winchester has developed 4 cartridges in this caliber over a 111 year time span;
(25-20 in 1893)
(25-35 in 1895)
(256 Winchester Magnum in 1960)
(25 Winchester Super Short Magnum in 2004).
The 25 WSSM cartridge, chambered in a super, short-action, light-weight rifle may well be the ultimate combination for the 1 gun hunter of strictly varmints, predators, and white-tailed deer size game..25 Winchester Super Short Magnum (WSSM) For Sale
