The .25 Winchester Super Short Magnum is a third member of the Winchester Super Short Magnum (WSSM) cartridge family created by Winchester and Browning. It is the largest caliber of the WSSM's and is the most capable of handling large game such as deer and wild boar. ==Description== It is a necked-up version of the .243 WSSM,〔 * (The .25 WSSM by Chuck Hawks )〕 which is in turn a shortened .300 WSM (Winchester Short Magnum). The WSSM cartridges are based on ballistics design philosophies that are intended to produce a high level of efficiency.〔(Browning WSSM info )〕 Like other WSSM cases, the .25 is short and fat, which is designed to be more efficient. Unlike the other WSSM rounds, the .25 is a magnum in name only, based on the case it uses. Performance wise it is a clone of the .25-06 Remington, making it well suited for medium to large game.〔(The Overlooked .25 Caliber Cartridges by Chuck Hawks )〕 The 25 WSSM provides the same performance as the 25-06 Remington, with the advantage of having lighter short action rifles. Having the short fat design, the cartridge loads burn at a more consistent rate, providing a higher level of accuracy. Performance is far less than other .25 caliber magnum rounds as the .257 Weatherby Magnum. In fact, ballistically it's almost identical to the improved version of the .257 Roberts, which P.O. Ackley said was his favorite choice for an all-around cartridge.〔''Handbook for Shooters & Reloaders vol I, Book by P.O.
