The .458 Winchester Magnum came about in the mid 20th Century, but has had a lasting impact on the hunting world. The cartridge sets the modern standard in taking down dangerous game.

The .284 Winchester nearly fell into obscurity due to lack of popularity. But the cartridge was born again as the 6.5-284 Norma and found new life among F-Class and other long-distance shooters.

When it was first developed the .300 Weatherby Magnum produced nearly unheard of velocities. Around 70 years later, and the round is still consider one of the world's blistering hot magnums.

The heavy and powerful .44 Magnum first became a factory load in 1956, but it wasn't until the early 70s the round's popularity went into the stratosphere. All it took was Dirty Harry welding a hand cannon chambered for the load to send it flying off store shelves.

The 6mm/.244 Remington traveled a twisting road on its way to gaining a foothold in the shooting world. Name changes were partly necessary for the cartridge to earn its place.

Legendary professional hunter Harry Selby launched the .416 Rigby into the limelight. The cartridge's performance in magazine-fed rifles and against dangerous game kept it popular.

Whether it's used to hunt elk or dissuade a motivated brown bear, the .338 Winchester Magnum has few equals. It is truly a cartridge for the last frontier.

The .22-250 has been a favorite cartridge among target shooters and varmint hunters alike. With breathtaking velocities and a wide spectrum of loads, there's a lot to love about the small-caliber cartridge.
