The .300 Winchester Short Magnum is a 7.62mm short action magnum cartridge with considerable effect. It is very similiar to the regular .300 Winchester Magnum in terms of ballistics, but takes advantage of the short action design which allows more powder to sit closer to the flash hole. When the primer ignites, it allows a more uniform burn which in turn translates into more efficient use of energy. A 300 WSM can therefore achieve the same ballistics with less powder.Norma Bondstrike is an advanced hunting cartridge design, based on a bonded boat-tail bullet with ballistic tip for extreme performance at the highest possible ranges.VelocityV0 3084 f/sV100 2926 f/sV200 2773 f/sV300 2625 f/sEnergyE0 3801 ft.-lbE100 3422 ft.-lbE200 3073 ft.-lbE300 2754 ft.-lbWind100yds 0.23 in200yds 0.94 in300yds 2.16 in
