Be very sure your rifle is bored for bullets of .323 inch diameter. Designed and constructed specifically for the 8mm Remington Magnum, this sleek 220 grain #2420 Spitzer Boat Tail bullet is an outstanding choice for the largest game on the North American continent and for African plains game. This bullet has an extremely heavy, double-tapered jacket for deep, smashing penetration. Sierra’s classic SBT shape ensures a flat trajectory, minimum sensitivity to crosswinds and vertical winds, and exceptional accura- cy. It will prove to be too “hard” at 8x57mm velocities, and is not recommend- ed for use in any cartridge producing less than magnum-level velocities
