.338 Lapua Magnum

The .338 Lapua Magnum is what happens when military snipers look at .300 Winchester Magnum and say “not far enough.” It’s a large-caliber, long-range rifle cartridge designed for extreme distances — we’re talking confirmed kills past 2,000 meters in military applications. The .338 Lapua fires a .338-inch bullet with enough ballistic coefficient and muzzle energy to stay supersonic well past the ranges that send other cartridges tumbling. If you’re serious about long-range precision shooting, this is the cartridge that serious people are serious about.

The .338 Lapua Magnum was developed in the 1980s through a collaboration between Research Armament Industries in the U.S. and the Finnish company Lapua. The U.S. military wanted a cartridge capable of defeating body armor at 1,000 meters — an ambitious requirement that drove the design toward a large, high-BC projectile at serious velocity. Lapua refined the cartridge through the late 1980s, and by the early 1990s it was in use with military and law enforcement units across Europe and eventually with U.S. forces as well. Its profile rose dramatically after the wars in Afghanistan and Iraq, where snipers needed to reach out across open terrain at distances that humbled .308 Winchester and even .300 Win Mag. The records it has set and the distances at which it has been used operationally are not the kind of thing that requires exaggeration.

Military and law enforcement long-range sniping is what put this cartridge on the map, and it remains the chambering of choice for many professional precision shooters. In the civilian world, it dominates competitive long-range shooting — 1,000-yard benchrest, ELR (Extreme Long Range) competition, and PRS-style matches where the targets are small and the distances are not. It’s also a capable big-game cartridge for hunters pursuing large and dangerous game at extended distances. If you’re building a rifle to shoot past where most people even think to aim, the .338 Lapua is where the conversation starts.

Standard .338 Lapua Magnum loads push a 250-grain bullet at approximately 2,940 feet per second, generating around 4,800 foot-pounds of muzzle energy. The high ballistic coefficient bullets it typically uses — the 250-grain Scenar and similar match projectiles — retain velocity exceptionally well at distance. It stays supersonic past 1,500 meters under standard conditions. At 1,000 yards it still hits with more energy than most rifle cartridges deliver at the muzzle. Recoil is substantial — plan accordingly, and appreciate your muzzle brake. This is not a cartridge for lightweight rifles or inattentive shooters, but for those willing to manage it, the capability it offers is genuinely extraordinary.

Lapua manufactures premium match ammunition in several loads, including their legendary Scenar and Scenar-L match bullets — the gold standard for precision shooters. Hornady loads .338 Lapua in their Precision Hunter and Match lines. Federal offers it in their Gold Medal and Terminal Ascent series. Given the cost of the rifle and the demands of the shooting it’s typically used for, most serious .338 Lapua shooters handload. Brass quality from Lapua is exceptional and lasts for many reloads. Bullets in .338 caliber with high BCs are available from Berger, Sierra, Hornady, and others. This is a cartridge where ammunition quality directly translates to performance at extreme range.

The .338 Lapua Magnum requires a magnum-length action and a bolt face sized accordingly — this is not a round you retrofit into a standard hunting rifle. Purpose-built precision rifles are the norm. Barrett, Accuracy International, Sako, Savage, Remington, Ruger, and others chamber rifles for it. The AI AXMC and the Barrett MRAD are iconic platforms in this caliber. Muzzle brakes are essentially standard equipment — the blast and recoil without one are uncivilized. Suppressors are popular with those who want to keep their hearing and their shooting experience more pleasant. Whatever platform you choose, expect a heavy rifle built around the demands of the cartridge.

We carry .338 Lapua Magnum ammunition and can discuss rifle options for this caliber. If you’re stepping into extreme long-range shooting and the .338 Lapua is on your list, come in and talk to us. We’ll help you think through the full setup — not just the cartridge, but the platform, optics, and support gear that make it work.
