Frequently Asked Questions
Buy .338 RUM Ammo for Sale
What is a .338 rum?
.338 RUM (Remington Ultra Magnum) is a large-bore rifle cartridge introduced in 2000, firing .338" diameter bullets at high velocity. Designed for hunting large game and long-range shooting, it remains an active cartridge and is considered a capable alternative to the .338 Lapua for extended-range work.
Is a 338 too big for deer?
No. .338 cartridges work fine on deer, though they're overkill for the job. Lighter calibers like .308 or .30-06 are more practical and economical. If you already own a .338 rifle, use it—proper bullet selection matters more than caliber. Recoil is the real downside for smaller game.
How much does a 338 drop at 500 yards?
Drop depends on the specific .338 variant, bullet weight, muzzle velocity, and zero distance. A .338 Lapua with a 250-grain bullet zeroed at 100 yards drops roughly 38 inches at 500 yards. Use a ballistics calculator with your exact load specs for precision.
How far will a 338 shoot accurately?
Accuracy depends on cartridge, rifle, ammunition, and shooter skill. .338 Lapua shoots sub-MOA to 1,200 yards reliably, around 2 MOA at 1,500–1,600 yards. Some shooters push past 2,000 yards. .338 RUM performs similarly. Wind and environmental conditions heavily influence performance at extreme distances.
How much recoil does a 338 rum have?
.338 RUM generates roughly 37–38 foot-pounds of free recoil energy in a standard-weight rifle. That's significantly more than a .338 Win Mag. Many shooters add a muzzle brake to manage it, and reduced loads still deliver strong performance while cutting felt recoil noticeably.
Is a 338 more powerful than a 300 win mag?
It depends which .338 you mean. The .338 Win Mag generates roughly 250 more foot-pounds of muzzle energy than the .300 Win Mag with comparable bullets. Cartridges like the .338 RUM produce even more energy. At longer ranges, .338 cartridges retain energy better. Under 300 yards, both perform similarly on game.
Is 338 more powerful than 30-06?
Yes, most .338 cartridges deliver more energy than .30-06. A .338 Win Mag generates roughly 250 more foot-pounds at the muzzle. The .338 Lapua retains significantly more energy at extended range—around 1,180 foot-pounds more at 500 yards. Under 300 yards on game, both perform comparably.
How far will a 338 shoot?
.338 cartridges vary widely in effective range. .338 Lapua shoots accurately past 1,500 yards and carries lethal energy beyond 2,000 yards. .338 Win Mag and .338 RUM typically excel to 1,000–1,200 yards. Actual distance depends on barrel length, ammunition, shooter skill, and environmental conditions.
