Weatherby‘s Select Plus line in 340 Weatherby Magnum (brand part no. H340250IL) pairs the big-case magnum with a 250-grain Hornady Interbond bullet for hunters who want serious weight behind serious velocity. Roy Weatherby introduced the 340 in 1963 as a response to the .338 Winchester Magnum, taking advantage of the longer Weatherby case to pack in more powder and push heavier .338-caliber bullets at higher velocities than the Winchester round could match. The Interbond’s bonded core chemically fuses jacket to lead, resisting separation on impact and driving deep penetration on the largest game the cartridge is built for. For 340 Weatherby Magnum hunters who want a premium factory load behind that extra case capacity, this rifle ammunition is built for the field.
