Weatherby Select Plus 338-378 Weatherby Magnum 225gr Barnes TTSX Lead-Free 20RD Ammo
Weatherby
The Weatherby Select Plus .340 Weatherby Magnum load pairs premium magnum performance with Barnes TTSX bullets engineered for hunters demanding hard-hitting, lead-free ammunition. Built on the flat-shooting foundation of the .340 Weatherby Magnum cartridge, this 225-grain load delivers the velocity and energy needed for distant, decisive shots on big game. The Barnes Tipped Triple-Shock X bullet design offers excellent expansion and penetration while meeting lead-free regulations in California and other restricted areas.
Weatherby Select Plus ammunition is purpose-built to combine the velocity advantages of magnum cartridge design with proven bullet engineering from respected manufacturers. The 225-grain TTSX at 2970 fps muzzle velocity generates 4408 foot-pounds of energy—the kind of downrange power long-range hunters rely on when precision and terminal performance matter. Whether you're working with a .340 Weatherby Magnum rifle already in your cabinet or considering one, this ammunition represents a serious, hunting-ready option that performs consistently from shot to shot.
The lead-free construction makes this load compliant where traditional ammunition faces restrictions, broadening where and when you can hunt without compromising on terminal ballistics or trajectory. Twenty rounds per box gives you enough to work up loads, practice, or stock for the season.
