.300 Weatherby 180 Grain Nosler Partition~ Roy Weatherby already had experience with other custom cartridges such as his own .270 Weatherby Magnum when he created the .300 Weatherby. Like most of his other magnum cartridges, this is based on a blown-out .300 H&H Magnum case, using the signature Weatherby double-radius shoulder.
It is often debated which came first the 300 Winchester Magnum or the 300 Weatherby Magnum, the Weatherby was first 1944 vs the Winchester was introduced in 1963. With the .300 Remington Ultra Magnum being introduced in 1999. Historically, Weatherby claimed that this is the most powerful .30 caliber magnum rifle commercially available, but the recently introduced .300 RUM and Weatherby’s own .30-378 Weatherby Magnum are now more powerful. One could say, the .300 Weatherby was 50 years ahead of its time as it has only been recently that suitable optics and range finders for long range hunting have been available to the public at affordable prices.
The .300 Wby is in common use by big-game hunters all over the world.

Partition Bullets feature a fully tapered jacket that ruptures instantly at the thin jacket mouth, yet the gradual thickening along the bullet’s axis controls expansion and curls the jacket uniformly outward at high or low velocities. Nosler’s integral Partition supports the expanded mushroom and retains the rear lead alloy core. The enclosed rear core retains more than half the original bullet weight for deep penetration. The special crimp locks in the rear core section, adding strength to resist deformation under the pressure of heavy magnums.This makes this round no match for Deer, Sheep, Pronghorn and Black Bear and other medium-sized game.
