The .270 Weatherby Magnum cartridge was developed by Roy Weatherby in 1943 and was the first belted magnum to be offered to the public when he open his business in 1945.
The InterLock® features an exposed lead tip for controlled expansion and hard-hitting terminal performance. A secant ogive design — one of the most ballistically efficient profiles ever developed. The raised ring inside the jacket is embedded in the bullet, combined with the one-piece core, keeps the core and jacket locked together during expansion to retain mass and energy.
