Weatherby‘s Select line in 340 Weatherby Magnum (brand part no. H340225IL) pairs the big-case magnum with a 225-grain Hornady Interlock bullet, giving hunters a dependable factory load built around the cartridge’s real advantage. Roy Weatherby introduced the 340 in 1963 as an answer to the .338 Winchester Magnum, using a longer case to pack in more powder and push heavier .338-caliber bullets to higher velocities than the Winchester round could reach. The Interlock bullet uses an internal mechanical locking ring that grips the jacket to the core, resisting separation on impact without the added cost of a fully bonded design. For 340 Weatherby Magnum hunters who want proven Hornady bullet performance without stepping up to the Select Plus tier, this rifle ammunition gets the job done.
