.270 Weatherby Magnum
It has been called the ultimate long-range deer caliber and a .270 Winchester on steroids. When Roy Weatherby began developing his belted magnum calibers in 1943 this was his first. Based on the .300 H&H Magnum and sporting the characteristic Weatherby double radius shoulder, it was necked down to accommodate the .277 bullet. Its average gain of about 200ft/s over other .270 calibers make it an excellent choice for long-range hunting of medium size game including deer, elk, and pronghorn.
Derek Peterson, president of Peterson Cartridge explains, “To emphasize the importance Roy Weatherby placed on the .270 Weatherby Magnum you need to remember that it was the first magnum cartridge he developed. Everything else followed from there. A lot of people do not know this but the first Weatherby cartridge used in Africa was a .270 Weatherby Magnum used to harvest a jackal back in 1948. When we decided to pair our casings with such an iconic caliber, we couldn’t wait to see the result. We know what we think of it, but we want to hear from you, so load some up and let us know how we did.”
