(50) ct of new Norma 257 Wby Mag brass (257 Weatherby Magnum).

The .257 Weatherby was one of Roy Weathernby’s earliest creations and quickly became his favorite. This flat shooting cartridge has grown to be one of Weatherby’s most popular rounds.

With the ability to fire a 115 gr Nosler Ballistic Tip bullet at an impressive velocity of 3,400 ft/s, the .257 Weatherby Magnum generates a staggering 2,952 ft⋅lbf of energy. This remarkable power sets it apart from its counterparts, especially when compared to the 25-06 Remington cartridge.

Perfectly suited for hunting pronghorn, smaller deer species, mountain sheep and goat, as well as small predators, the .257 Weatherby Magnum combines accuracy and knockdown power for a superior hunting experience. However, it's important to note that it is not recommended for use on dangerous game species even though Roy Weatherby demonstrated it's ability to take a cape buffalo.

Weatherby continues to chamber the .257 Weatherby Magnum in several rifle models, ensuring a wide range of options for shooters. 

It's essential to mention that the .257 Weatherby Magnum has a high overbore index, which can impact barrel life and throat erosion. But fear not, these concerns can be mitigated by following recommended cleaning procedures and allowing the barrel to cool between shots. For those seeking extended barrel life, rifles chambered in this caliber can benefit from the use of stainless steel barrels.

In earlier models, a slower twist rate necessitated specific bullet types. However, handloading this Norma brass with heavier bullets specifically designed for rifles with slower spin rates, provides even more versatility and options for shooters.

In conclusion, the .257 Weatherby Magnum is a true marvel in the world of long-range hunting. With its exceptional performance, accuracy, and availability, it's no wonder that this cartridge continues to be a top choice among experienced hunters.
