The .257 Magnum is one of the early Weatherby calibers, designed in 1944. It is one of the most popular Weatherby calibers, combining very high velocity, flat trajectory, and tolerable recoil. It is reputed to have been Roy Weatherby's favorite cartridge.
Weatherby offers several factory loads for the .257 Mag. The lightest bullet available is an 87 grain Hornady Spire Point Bullet at 3825 fps, which is the varmint and predator load for the caliber. For medium game such as deer and the smaller antelope species at long range there is a 100 grain Hornady Spire Point bullet at 3602 fps and a 115 grain Nosler Ballistic Tip bullet at 3400 fps. For woods and brush country hunters there is a 117 grain Hornady Round Nose bullet at 3402 fps. For larger or tougher game Weatherby offers a 115 grain Barnes X-Bullet spitzer at 3400 fps, and a 120 grain Nosler Partition spitzer bullet at 3305 fps.
