Weatherby Select 340 Weatherby Magnum 225 Grain Hornady InterLock Spire Point Ammunition - 20 Rounds

Weatherby Select 340 Weatherby Magnum ammunition pairs factory precision with Hornady's proven InterLock projectile—a combination that delivers the stopping power and deep penetration serious magnum hunters demand. Each round fires a 225-grain Hornady InterLock Spire Point bullet at 3066 feet per second, generating 4696 foot-pounds of energy at the muzzle. This is ammunition engineered for the long-range hunter willing to step up to a true magnum caliber for elk, moose, and other large game where energy retention and controlled expansion matter.

Hornady's InterLock design pairs a secant ogive—the company's trademark ballistic-efficiency feature—with a locked-core construction that resists core-jacket separation on impact. That geometry maximizes bearing surface for stable flight and consistent velocity performance, while the spire point profile cuts wind deflection at extended ranges. Weatherby Select represents factory-fresh, consistently loaded ammunition that takes the guesswork out of feeding a demanding magnum.

If you're running a 340 Weatherby Magnum rifle, this is the kind of round that justifies the platform. The 225-grain bullet weight sits in the sweet spot for the cartridge—heavy enough to retain energy over distance, but not so heavy that velocity suffers. Twenty rounds per box means you get a full hunting season's worth of confidence in one package.
