Frequently Asked Questions
Buy .300 REM SA ULTRA MAG Ammo for Sale
What is a 300 ultra mag good for?
The .300 Remington Ultra Magnum suits long-range big game hunting and precision shooting. It pushes 180-grain bullets near 3,300 fps, producing flat trajectories and strong retained energy at distance. Recoil is heavy, making a muzzle brake worthwhile. It handles elk, moose, and similar large game effectively.
What is the effective range of a 300 rem ultra mag?
The 300 RUM is a long-range powerhouse. With high-BC projectiles like the 208gr A-Max, skilled shooters can achieve fast kills out to around 1,400 yards. Even at 1,000 yards, the cartridge retains sufficient energy for hunting purposes. Wind conditions and shooter ability ultimately determine practical range.
Who makes a 300 ultra mag rifle?
Remington introduced the .300 Ultra Magnum cartridge in 1999 and chambers it in their Model 700. Savage, Browning, and several custom rifle makers also produce rifles in this caliber.
How hard does a 300 ultra mag kick?
A 300 RUM is a hard-kicking rifle—a 9-pound build with a 230gr bullet generates around 41 ft-lbs of recoil energy, and lighter rifles hit harder still. Most shooters find it punishing during extended range sessions. A muzzle brake cuts that significantly.
What is the cost of .300 Ultra Mag ammunition?
.300 Remington Ultra Magnum ammunition typically costs around $73 per box, with prices ranging from approximately $85.99 to $132.99 depending on bullet weight, manufacturer, and load type.
What is the difference between 300 mag and 300 ultra mag?
.300 Win Mag fires 180gr bullets around 3,100 fps, while .300 RUM reaches roughly 3,300 fps due to its larger case capacity and more powder. RUM delivers greater velocity and downrange energy with a beltless case, but Win Mag ammunition is cheaper and recoil is more manageable.
