Remington Premier 300 Remington Ultra Magnum 180 Grain Swift Scirocco II - 20 Rounds

The Remington Premier 300 Remington Ultra Magnum 180 Grain Swift Scirocco II is a premium big-game rifle cartridge built for hunters who demand reliable performance on demanding hunts. This 20-round box pairs the swift, flat-shooting ballistics of the 300 RUM with the proven terminal performance of Swift's Scirocco II bullet—a combination that delivers the accuracy and energy retention serious long-range hunters depend on.

The Scirocco II bullet itself is the star here. It features a precision-engineered polymer tip that cuts through air efficiently, a secant ogive profile for a high ballistic coefficient, and a boat-tail design that further reduces drag downrange. The result is a flatter trajectory and less wind drift—real advantages when hunting at extended ranges or in open country. The heavy-based pure copper jacket is bonded to the lead core, which prevents jacket-core separation and ensures the bullet retains over 75% of its weight even at the velocity levels the 300 RUM generates. That weight retention is crucial for deep, reliable penetration on large game.

Whether you're preparing for a western elk hunt, planning a pronghorn expedition, or setting up for a long-range rifle competition, this ammunition combines the extended-range capability of the 300 RUM cartridge with a bullet designed to perform consistently across velocities. The precision concentricity and proven accuracy of the Scirocco II make this a solid choice for shooters who won't accept mediocrity in the field.

Frequently Asked Questions

What game is this ammunition suitable for?

The 300 RUM with a 180-grain Scirocco II bullet is designed for big-game hunting. The high velocity and energy retention of the cartridge, combined with the bonded bullet's deep penetration and weight retention, make it effective on large game species.

How does the bonded jacket help terminal performance?

The bonded construction locks the copper jacket to the lead core, preventing separation during impact. This ensures the bullet retains over 75% of its weight, which supports deeper penetration and more consistent performance across a range of velocities and impact distances.

Why does the boat-tail and polymer tip design matter?

The boat tail reduces drag at the rear of the bullet, while the polymer tip reduces frontal air resistance. Together with the high ballistic coefficient from the secant ogive profile, these features help the bullet maintain velocity and trajectory over distance, which translates to flatter shooting and less wind drift at extended ranges.

Is this ammunition suitable for long-range hunting?

Yes. The 300 RUM cartridge is built for extended-range capability, and the Scirocco II's high ballistic coefficient and aerodynamic design support that role. The precision concentricity also contributes to the accuracy consistency needed for confident shots at distance.
