Doubletap Ammo 257Wb120P 257Wthby Mag 120Gr Nosler Partition 20 Per Bx

Double Tap's 257 Weatherby Magnum load pairs premium Nosler Partition bullets with the velocity and flat trajectory this cartridge is known for. Built for hunters who've invested in 257 Weatherby rifles and demand ammunition that delivers both accuracy and reliable terminal performance at distance. Each box contains 20 rounds loaded with 120-grain Nosler Partitions—a proven cup-and-core design that has earned its reputation across decades of hunting applications.

The Nosler Partition's distinctive design splits the bullet into two lead cores, separated by a copper interbond. The front core is built for expansion and energy transfer on impact; the rear core remains mostly intact to ensure penetration and a consistent exit wound. This dual-core architecture means you get reliable expansion without the unpredictable performance or velocity loss sometimes associated with other bonded designs. For the 257 Weatherby hunter, it's the kind of thoughtful ammunition engineering that pays off when it matters.

Double Tap Ammunition manufactures this load to consistent standards, so you can count on uniform velocities and repeatability from shot to shot. Whether you're working up loads for a custom rifle, running a proven handload recipe, or simply restocking for the season, this 257 Weatherby ammunition delivers the quality control and component consistency that separates purpose-built ammunition from generic commodity rounds.
