The 280 AI was developed by Parker Otto (P.O.) Ackley. P.O. was a lot like Roy Weatherby, a wildcatter who was in search of better solutions. His 280 AI set out to improve the .280 Rem by steeping the shoulder to 40 degrees to increase powder capacity. Weatherby is known for ballistics and velocity, our 280 AI offerings will push the industry standards on both.

It was then registered by SAAMI in 2007 by Nosler and has been an underserved cartridge in the market.
Our line-up of offerings are intended to provide the market with premium hunting options.
Listen as the Weatherby Team sits down to talk about our new Non-Weatherby loaded ammunition.
Hammer Bullets™ are turned on a CNC lathe and use a unique solid copper blend that is designed for maximum terminal performance. Each bullet is weighed and micrometer measured as it is produced. The result is an incredibly consistent product with unparalleled quality control. The hollow point design, initiates expansion upon impact, shedding petals immediately, with the remainder of the bullet staying intact with a blunt front for optimal wound channel. All Hammer Custom Bullets are designed to optimize Weatherby’s flat shooting cartridges.
Take a deeper dive into Hammer Bullets with our On Our Mark podcast. We sit down with Bryan and Steve of Hammer Bullets to talk about the performance and what makes Hammer bullets different from similar projectiles.

A bonded bullet with Swift’s signature black tips designed for hunting and long-range efficiency. Pure copper jacket is progressively tapered to control expansion development throughout a wide range of velocities. Jacket and core are joined together using proven Swift bonding technology. Long driving band for improved rotational stability. Its sleek design and advanced secant ogive nose profile allows for high ballistic coefficient that produce flat trajectories for downrange hunting, making it a perfect match for Weatherby Cartridges.
