It is the largest caliber of the WSSM's and is the most capable of handling large game such as deer and wild boar. It is a necked-up version of the .243 WSSM, 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. Like other WSSM cases, the .25 is short and fat, which is designed to be more efficient. However, short fat cases with an abruptly angled shoulder and have been criticized by some as being difficult to feed properly in some rifles. Unlike the other WSSM rounds, the .25 is a magnum in name only, based on the case it uses. Performance wise it is almost exactly between the .257 Roberts and the .25-06 Remington, making it well suited for medium to large game. Performance is far less than other .25 caliber magnum rounds as 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.
