300 Win Mag
The .300 Win Mag is a belted, bottlenecked magnum cartridge that is designed to be a versatile cartridge for hunters, military snipers, competition shooters, and law enforcement organizations. If you’ve ever shot a .300 Win Mag, you know how much power and felt-recoil they have, but it’s still a very popular and reliable cartridge for hunters all over the world.
The diameter is the same as the .308 Winchester cartridge, but the base diameter is almost wider and the case is longer to accommodate the added pressure. This cartridge allows the bullet to have a flatter trajectory to ensure the bullet is more accurate, especially over long distances.

300 Remington Ultra Mag
The .300 Remington Ultra Magnum is designed to be one of the largest .30 caliber magnum cartridges on the market. The .300 Ultra Mag is an incredible hunting rifle that has been shown to outperform the ballistics of the .300 Winchester Magnum.
The Ultra Mag isn’t belted and the rim is rebated, like the .300 Win Mag. A rebated rim means that the rim’s diameter is smaller than the base of the case. This is designed to provide better feeding and extraction from the breach of the rifle. You’d be able to take any game in America with this rifle at longer ranges than both the .308 Win and .300 Win Mag. However, I’d never shoot a whitetail with a .300 Rem Ultra Mag.

Browning X-Bolt Hell’s Canyon
The Browning X-Bolt Hell’s Canyon Speed Long Range McMillan rifle features the Browning patented adjustable Feather Trigger finished with a gold plating. A detachable rotary 3-round magazine speeds up follow-up shots if you need to reload. The barrel and receiver are finished with very durable and expensive Cerakote burnt bronze. With a 1:8″ twist rate, this rifle can feed and fire some of the heaviest bullets made. This is important because it allows the rifle to shoot at further distances. It helps significantly to have a 26″ barrel instead of the standard 24″ because it gives you more range and control over longer ranges.
