338 Lapua Magnum Ballistics: Complete Data Guide With Drop Charts, Load Comparisons & Long-Range Performance

1. What Is .338 Lapua Magnum?

The .338 Lapua Magnum was developed in the 1980s as a purpose-built long-range military sniping cartridge. The Finnish company Lapua refined the case design after earlier attempts by Research Armament Industries, creating a cartridge that could reliably engage targets at 1,500+ meters with a man-portable rifle — something previously requiring a .50 BMG platform weighing over 30 pounds.

The .338 Lapua pushes .338-caliber bullets (8.6mm) weighing 250–300 grains at 2,700–3,000 fps, generating 4,800–5,000+ ft-lbs of muzzle energy. That places it squarely between the .300 Win Mag (roughly 3,500 ft-lbs) and the .50 BMG (roughly 12,000 ft-lbs) in the energy hierarchy. More importantly, the .338 Lapua achieves this from rifles weighing 14–18 pounds — less than half the weight of a .50 BMG platform.

What makes the .338 Lapua special is the combination of high BC .338-caliber bullets and the case capacity to drive them fast. The 300-grain Lapua Scenar with a BC of .891 and the 300-grain Sierra MatchKing at .768 are among the most aerodynamically efficient projectiles available in any caliber. That efficiency translates directly into less drop, less wind drift, and more retained energy at the ranges where this cartridge is designed to operate.

2. How We Evaluate .338 Lapua Performance

The .338 Lapua Magnum is evaluated primarily on external ballistic performance — trajectory, wind drift, retained velocity, and energy at distance. These metrics matter more than close-range gel testing for a cartridge designed around 800–1,500 yard engagements. Traditional gel tests at 10 feet don’t tell you much about a cartridge whose real-world use case starts at ranges where most rifles become ineffective.

That said, terminal performance data exists from military testing and hunting applications. We include gel-equivalent terminal data where available, focusing on bullet behavior at both close range (muzzle velocity impact) and at extended range (simulated 800 and 1,000-yard impact velocities). The latter is far more relevant for understanding what the .338 Lapua actually does to a target at the distances where you’d choose it over a .300 Win Mag.

Chronograph data is captured from typical civilian barrel lengths (26–27 inches) rather than military test barrels. All drop and drift calculations use published G1 and G7 ballistic coefficients verified against manufacturer data, with a 100-yard zero unless otherwise noted.

3. .338 Lapua Ballistic Data — 6 Factory Loads Compared

Key takeaway: The 300-grain loads (Lapua Scenar, Berger Hybrid) deliver the best long-range performance despite slower muzzle velocities. Their BCs of .818–.891 mean they overtake the faster 250-grain loads in velocity retention by roughly 600 yards and maintain a commanding advantage past 1,000. For any precision application beyond 800 yards, the 300-grain class is the correct choice.

4. Terminal Ballistics & Gel Test Performance

At .338 Lapua velocities, terminal effects on soft tissue are devastating. The combination of large-caliber (.338″) bullets, high velocity, and massive energy creates wound channels that exceed anything in the standard rifle cartridge lineup short of .50 BMG.

The data reveals a clear split between match bullets and hunting bullets. The Lapua Scenar 300gr — the premier match bullet — is not designed to expand. It penetrates deeply with minimal expansion, maintaining 98% weight retention. This is ideal for precision target shooting but produces a narrow wound channel relative to the cartridge’s energy.

The Hornady ELD-X 270gr behaves like a proper hunting bullet: controlled expansion at close range (0.68 inches), good weight retention (87%), and deep penetration (22 inches). At 500-yard impact velocity, expansion decreases but the bullet still performs reliably — a critical feature for a cartridge designed for extended-range hunting.

The Berger Hybrid 300gr produces the most dramatic terminal effect. Berger’s thin-jacket OTM design fragments aggressively upon impact, creating a wide wound cavity (0.75 inches expanded diameter) but shedding 27% of its weight. This is a devastating terminal performer on soft-skinned game but may not provide the deep penetration needed for heavy-boned animals at close range.

Key takeaway: Match bullets (Scenar, Sierra MatchKing) are not hunting bullets — they penetrate deeply without expanding. For hunting, choose the ELD-X 270gr for controlled expansion or the Berger 300gr for maximum tissue disruption.

5. Bullet Drop Charts — 100 to 1,500 Yards

All figures assume a 100-yard zero from a 27-inch barrel.

The Lapua Scenar’s BC advantage (.891 vs .587 for the 250gr SMK) compounds dramatically past 700 yards. At 1,000 yards, the Scenar drops 23 inches less than the 250-grain Federal load. At 1,500 yards, the gap widens to 130 inches — over 10 feet of difference. For ELR (Extreme Long Range) shooting, the 300-grain Scenar is the defining load of the .338 Lapua platform.

In practical terms, a 1,000-yard shot with the Scenar requires 5.4 mils of elevation — well within the adjustment range of any quality long-range scope. The 1,500-yard shot at 9.6 mils is also manageable with a properly equipped rifle. These are the engagement distances the .338 Lapua was designed for, and the drop data confirms the cartridge handles them comfortably.

Key takeaway: The .338 Lapua with 300-grain high-BC bullets is a legitimate 1,500-yard precision cartridge. Inside 700 yards, bullet weight matters less than accuracy. Past 700 yards, the 300-grain Scenar class pulls away dramatically.

6. Wind Drift at Extended Range

Wind drift is the primary accuracy challenge at .338 Lapua distances. Even this cartridge with its exceptional BCs drifts significantly at 1,000+ yards. All figures assume a 10 mph full-value crosswind.

Even the Scenar drifts 33 inches (nearly 3 feet) at 1,000 yards in a 10 mph wind. At 1,500 yards, drift exceeds 7 feet. This is why wind reading is the most critical skill in long-range shooting — and why most .338 Lapua shooters spend more time learning to read mirage, flags, and terrain effects than they spend at the bench.

The BC gap between the Scenar and the 250-grain Federal produces a 19-inch drift difference at 1,000 yards and a 55-inch difference at 1,500 yards. At ELR distances, that’s the difference between a hit and a clean miss on a man-sized target.

Key takeaway: Wind drift is the limiting factor in .338 Lapua accuracy at 1,000+ yards. Choose the highest-BC bullet your rifle shoots accurately, and invest your training time in wind reading skills.

7. Barrel Length and Velocity — 24″ to 30″

The .338 Lapua gains roughly 25–30 fps per inch of barrel. Going from 24 to 27 inches adds about 110 fps, which translates to roughly 10 inches less drop at 1,000 yards. Going from 27 to 30 inches adds another 80 fps — useful for competition but adds 3 inches of barrel length to an already long rifle.

Most purpose-built .338 Lapua rifles ship with 26–27 inch barrels. This represents the practical sweet spot between velocity, portability, and barrel harmonics. Competition rifles sometimes use 28–30 inch barrels for the extra velocity, but the additional weight and length make the rifle impractical for field use.

Key takeaway: A 26–27 inch barrel is the standard for .338 Lapua. Shorter barrels sacrifice meaningful velocity; longer barrels add marginal performance at the cost of handling.

8. .338 Lapua vs .300 Win Mag — When to Step Up

Inside 700 yards, the .300 Win Mag is nearly as effective as the .338 Lapua at roughly half the ammunition cost and 25% less recoil. At 700 yards, the trajectory and wind drift differences are small enough that shooter skill matters more than cartridge selection.

Past 1,000 yards, the .338 Lapua pulls away decisively. It drops 80 inches less, drifts 17 inches less in the wind, and delivers 75% more energy on target. At 1,500 yards, those gaps become chasms. The .338 Lapua maintains supersonic flight past 1,500 yards where the .300 Win Mag goes transonic and becomes ballistically unstable.

The cost difference is significant. A 100-round practice session costs $400–700 in .338 Lapua vs $150–300 in .300 Win Mag. Barrel life is shorter too — roughly 2,500–3,000 rounds for the Lapua vs 4,000–5,000 for the .300 Win Mag.

Key takeaway: If your shooting regularly exceeds 1,000 yards, the .338 Lapua is worth the investment. Inside 1,000 yards, the .300 Win Mag delivers 90% of the capability at half the cost.

9. .338 Lapua vs .50 BMG — Do You Really Need the Fifty?

The .50 BMG is ballistically superior at every distance — more energy, less drop, less drift. But the .338 Lapua achieves 85% of the .50’s trajectory performance in a rifle that weighs half as much and can be carried, deployed, and shot from field positions without vehicle support. That portability advantage is the reason the .338 Lapua was developed in the first place.

For most civilian precision shooters, the .338 Lapua covers every realistic engagement distance. The .50 BMG’s advantages — material penetration, extreme terminal authority, 2,000+ yard capability — are military requirements that civilian shooters rarely encounter.

Key takeaway: The .338 Lapua is the practical precision cartridge for civilian long-range shooting. The .50 BMG is for shooters who specifically need 2,000+ yard capability or anti-materiel terminal effects — and are willing to carry the weight.

10. .338 Lapua for Hunting — Effective Range by Game

The .338 Lapua is wildly overpowered for most North American hunting inside 500 yards. Its real hunting niche is extended-range elk and moose in open Western terrain where 600–1,000 yard shots are realistic. The Hornady ELD-X 270gr is the best hunting load — it delivers controlled expansion and adequate penetration across the full range of practical hunting distances.

Remember: the Lapua Scenar 300gr is a match bullet, not a hunting bullet. It will kill game through hydrostatic shock and tissue disruption, but it won’t expand reliably. For ethical hunting, choose a bullet designed for terminal expansion at the impact velocity you’ll encounter at your shooting distance.

Key takeaway: The .338 Lapua is a genuine 1,000-yard elk cartridge with proper hunting bullets. For most hunting applications, it’s more cartridge than you need — but if your hunting demands extreme-range capability, nothing else matches it in a man-portable rifle.

11. Frequently Asked Questions

What is the effective range of .338 Lapua Magnum?

Against man-sized targets, the .338 Lapua is effective to 1,500–1,800 yards in the hands of a skilled shooter with proper equipment. The current longest confirmed sniper kill (3,540 meters) used a .338 Lapua. For hunting, effective range depends on the game and bullet choice — roughly 1,000 yards for elk with expanding bullets, limited primarily by the shooter’s ability to read wind at distance.

How much does .338 Lapua recoil?

In a typical 14-pound rifle, the .338 Lapua generates approximately 35 ft-lbs of free recoil energy. That’s roughly 35% more than a .300 Win Mag and comparable to a lightweight 12-gauge shooting 3-inch magnum slugs. A quality muzzle brake reduces felt recoil by 40–50%, making extended shooting sessions practical. Most .338 Lapua rifles ship with brakes installed.

How much does .338 Lapua ammo cost?

Factory match ammunition costs $4–7 per round. Hunting loads from Hornady and Berger run $5–7 per round. Surplus or practice-grade ammunition is generally not available in .338 Lapua. Reloading reduces per-round cost to $1.50–3.00 depending on components, and most serious .338 Lapua shooters reload for both cost savings and accuracy optimization.

What barrel life can I expect?

Typical barrel life for a .338 Lapua is 2,500–3,500 rounds before accuracy degrades noticeably. Conservative shooting schedules (allowing barrel cooling between strings) extend barrel life toward the upper end. At $4–7 per round, most shooters will spend $10,000–25,000 in ammunition before needing a new barrel — making the barrel replacement cost relatively minor in context.

Is .338 Lapua legal everywhere?

The .338 Lapua Magnum is legal in all 50 U.S. states. Unlike the .50 BMG, no state has enacted caliber-specific restrictions on .338 Lapua. Some long-range shooting facilities require the cartridge due to their minimum distance capabilities, while some shorter ranges may prohibit it due to backstop limitations. Always verify range compatibility before your first session.

What scope do I need for a .338 Lapua?

A quality scope with at least 25–30 mils (85–100 MOA) of total elevation adjustment is essential. Popular choices include the Nightforce ATACR 7-35×56, Vortex Razor HD Gen III 6-36×56, and Schmidt & Bender PM II 5-25×56. Budget at least $1,500–3,000 for optics — the scope should cost as much as or more than the rifle for a precision .338 Lapua build. A 20 MOA canted rail is standard to maximize usable elevation range.
