.300 Wby. Mag.

By far the most popular and versatile Weatherby® cartridge available. The .300 Weatherby® Magnum had the flattest trajectory, longest range and the greatest killing power of any .300 magnum on the market until the .30-378 Weatherby® Magnum came along. Based on the .300 H&H Magnum, the .300 Weatherby® delivers 300 more fps than its British cousin. Introduced in 1944, this is the all-around cartridge for the big game hunter.

.300 Weatherby® Magnum is available in Mark V® models: Ultra Lightweight (RH and LH), Accumark (RH and LH), Accumark RC, Deluxe, Lazermark, Sporter, Fibermark Composite, Ultramark and Euromark. Also available in Vanguard® Series 2 models: Synthetic, Synthetic Package, Stainless Synthetic, Sporter, and Deluxe, Range Certified and Back Country.

20 cartridges per box.
