338 Lapua Mag Ammo

About .338 Lapua Magnum Ammo

Developed in the 1980s through a collaboration between Research Armament Industries and Lapua, .338 Lapua Magnum was purpose-designed as a long-range military sniper cartridge capable of defeating light cover and body armor at distances beyond 1,000 meters. It was formally adopted by NATO special operations forces and has seen widespread use by military snipers from the United Kingdom, United States, Canada, and numerous allied nations. Confirmed combat kills at distances exceeding 2,000 meters have been recorded with .338 Lapua Magnum — a testament to its extreme long-range capability in the hands of a trained shooter.

.338 Lapua Magnum fires a .338-inch diameter bullet, typically in the 250–300 grain range, at muzzle velocities of 2,750–2,970 fps. That combination of heavy, high-BC projectiles and high velocity produces exceptional retained energy and resistance to wind deflection at extreme distances — a 250gr load retains over 2,000 ft-lbs of energy past 1,000 yards and stays supersonic well beyond 1,500 yards. It is chambered in large-format bolt-action and semi-automatic precision rifles and commands a large, dedicated following among competitive long-range shooters, military and law enforcement precision teams, and serious big-game hunters.

What Is .338 Lapua Magnum Best For?

• Extreme long-range precision shooting: The primary use case the cartridge was built for. .338 Lapua Magnum is competitive in Extreme Long Range (ELR) competition and remains one of the most capable cartridges available for precision work at 1,000–2,000+ yards.
• Military and law enforcement precision applications: Widely used by special operations snipers and law enforcement precision teams worldwide. The combination of long-range capability, barrier penetration, and terminal energy makes it uniquely suited to these roles.
• Large and dangerous game hunting: At hunting distances, .338 Lapua Magnum is one of the most powerful practical hunting cartridges available. It is an outstanding choice for Alaska brown bear, moose, bison, and African dangerous game where maximum stopping power and deep penetration are required.
• Long-range hunting: For hunters pursuing game at distances exceeding 600 yards in open mountain or plains terrain, .338 Lapua Magnum provides a meaningful energy and wind-resistance advantage over any standard hunting cartridge.

Bullet Types Available

• Open Tip Match (OTM) / HPBT (250–300gr): Competition-grade precision loads optimized for extreme long-range accuracy. Lapua Scenar-L, Sierra MatchKing, and Berger Hybrid are the benchmark match projectiles for this caliber.
• Polymer Tip / ELD Match (250–285gr): Hornady's A-MAX and ELD Match loads deliver match-grade accuracy with higher BC ratings for reduced wind drift at extended ranges.
• Bonded Hunting (225–250gr): Controlled-expansion loads for dangerous and large game hunting. Federal Trophy Bonded and Nosler AccuBond Long Range deliver the penetration depth required on the world's largest animals.
• Solid / Monolithic (250–300gr): Solid copper or brass projectiles designed for maximum penetration on dangerous game. Required or preferred for certain African hunting applications.

Rifles Chambered in .338 Lapua Magnum

.338 Lapua Magnum requires a large-format action — it does not fit in a standard long-action receiver. Common platforms include the Accuracy International AXMC and AX338, Barrett MRAD, Remington MSR, Savage 110 BA, Ruger Precision Rifle, Tikka T3x TAC A1, Christensen Arms MPR, and numerous custom precision bolt guns. Semi-automatic platforms include the Barrett M98B and Desert Tech SRSA2. Rifles chambered in .338 Lapua Magnum are typically heavier and longer than standard hunting rifles, with muzzle brakes or suppressors used to manage the substantial recoil.

Frequently Asked Questions

How does .338 Lapua Magnum compare to .300 Win Mag?

.338 Lapua Magnum fires a significantly heavier, larger-diameter bullet with more muzzle energy and better wind resistance at extreme ranges than .300 Win Mag. At 1,000 yards, .338 Lapua Magnum retains roughly 500–700 ft-lbs more energy than a comparable .300 Win Mag load. The tradeoffs are substantially higher recoil, larger and heavier rifles, and significantly higher per-round cost. For precision shooting and hunting inside 800 yards, .300 Win Mag is the more practical choice for most shooters. Beyond 1,000 yards, .338 Lapua Magnum's advantages become increasingly meaningful. They are not interchangeable.

What is the effective range of .338 Lapua Magnum?

.338 Lapua Magnum stays supersonic past 1,500 yards with most 250–300gr loads and retains over 1,000 ft-lbs of energy well beyond that point. Confirmed precision hits have been recorded at distances exceeding 2,000 meters. In practical terms, a skilled shooter with quality equipment and favorable conditions can expect consistent first-round hits on man-sized targets at 1,500 yards and beyond. The cartridge itself is not the limiting factor at any distance a hunter or competitive shooter would reasonably attempt.

Is .338 Lapua Magnum legal for hunting in the United States?

Yes — it is legal for hunting in all U.S. states where centerfire rifle hunting is permitted. It is an exceptionally powerful choice for Alaska brown bear, moose, and bison. Some hunters use it for elk and deer at extreme ranges, though a less expensive and lighter-recoiling cartridge is more practical for those applications inside 600 yards.

How does .338 Lapua Magnum compare to .338 Win Mag?

.338 Win Mag fits in a standard long-action receiver and delivers strong performance on large game at hunting distances — roughly comparable inside 400 yards. .338 Lapua Magnum operates at significantly higher pressure, uses a larger case requiring a dedicated action, and delivers 400–600 fps more velocity with dramatically superior long-range performance. .338 Win Mag is the more practical hunting cartridge for most applications; .338 Lapua Magnum is the choice when extreme long-range capability is the priority. They are not interchangeable.

How much does .338 Lapua Magnum ammo cost per round?

Expect to pay roughly $3.00–$5.00/rd for standard loads and $5.00–$8.00+/rd for premium match-grade ammunition. .338 Lapua Magnum is one of the more expensive centerfire cartridges in production due to its large case, specialized components, and lower production volume. Buying in bulk is the most effective way to reduce your per-round cost.
