Jamison 356 Winchester ammo is loaded with a .358 diameter Sierra jacketed, round-nose projectile. This load is meant for hunting. The traditional, flat base design of the Pro-Hunter has been skillfully blended with Sierra's world-famous accuracy. The custom-tapered Pro-Hunter jacket design helps assure maximum expansion, optimum weight retention and deep penetration for game-stopping, 1-shot performance. The 35 Caliber 200 Grain Round nose was designed as a medium to big game bullet at short to medium ranges. This ammunition is loaded with smokeless powder and should only be used in firearms suitable for smokeless loads.
