Winchester Expands The Winchester Short Magnum Line
Shooters and hunters who like bigger bore rifles for large game hunting are expecting Winchester and Browning and Winchester Firearms to finally make the move to bigger bullets in the WSM line for 2005. They are right, but they may be surprised.
Winchester recognized the need for a cartridge capable of launching 200 plus grain bullets with high inherent accuracy, energy capable of stopping the largest North American game, and lower perceived recoil. Winchester engineers considered several different calibers during development and determined that the 325 caliber was the best performer in the WSM platform. This new cartridge delivers similar energies as a 338 Win-Mag in a much smaller lightweight package.
The platform of the "Short-Fat" cartridge design has for years consistently produced very accurate cartridges. Since their introduction, the Winchester Short Magnum and the Winchester Super Short Magnum calibers have all produced exceptional accuracy. In addition to delivering excellent ballistics, the 325 WSM also exhibits exceptional accuracy, a real plus in this large caliber cartridge.
Initially, three loads will be available in the 325 WSM. Winchester Ammunition and Nosler, Inc. developed a 200 gr. Accubond® CT® in the Supreme® line and in the Super-X® line, Winchester Ammunition developed a 220 gr. Power-Point® bullet. Both of these loads utilize bullets specifically designed for use in the 325 WSM. Additionally, a 180 gr. Ballistic Silvertip® in the Supreme® line will be available. Additional loads are expected in the future.
The 325 WSM is the ideal package for the serious elk, bear, moose or other large and dangerous game hunter where a lightweight short magnum rifle is desired.
Please see the preliminary ballistics for the 325 WSM below.
