Description
When you need ammunition from the company that literally created the cartridge, Lapua's 300 grain .338 Lapua Magnum load is built for shooters who take their long-range game seriously. Developed by the Finnish ammunition manufacturer that originated this legendary cartridge, this load pairs heavy 300 grain hollow point boat tail projectiles with consistent powder charges and premium brass for match-grade performance you can count on.
The 300 grain bullet weight is the heavier choice for the .338 Lapua, and there's a reason competitive precision shooters and serious hunters reach for it. Compared to lighter 250 grain loads, the 300 grain projectile delivers superior ballistic coefficients and wind resistance, which means flatter trajectories and less drift at extreme distances. At 2723 feet per second, you're getting muzzle energy and downrange performance that maintains its velocity and striking power well beyond 1,000 yards.
What Sets Lapua's .338 Lapua Magnum 300gr Load Apart
Lapua ammunition carries a pedigree you won't find elsewhere. The company spent years perfecting case design and construction before commercializing this cartridge in the late 1980s, and that engineering expertise shows up in every round. Each cartridge features carefully selected brass with proper case geometry for reliable feeding and consistent chamber pressure. The hollow point boat tail design reduces drag and promotes a faster velocity, while the pronounced boat tail provides exceptional flight characteristics across varying velocities.
Match-Grade Specifications for Precision Results
These aren't generic commodity rounds. Lapua loads each round to exacting tolerances, which is why you'll see this ammunition used by military snipers, tactical professionals, and competitive long-range competitors worldwide. The 10-round packaging reflects this premium positioning—you're getting quality over quantity, which matters when each shot counts and ammunition costs what it does.

Frequently Asked Questions
What's the difference between 300 grain and 250 grain .338 Lapua ammunition?
The heavier 300 grain bullet delivers higher ballistic coefficients and better wind resistance compared to 250 grain loads, making it the preferred choice for extreme long-range shooting beyond 1,000 yards. You trade some velocity for better energy retention and trajectory stability at distance. Most competition long-range shooters and serious hunters opt for the 300 grain when they're pushing the cartridge's effective range.
Is Lapua .338 Lapua Magnum ammunition suitable for handloading?
Yes. Lapua brass is highly valued by reloaders for its consistent quality, proper case geometry, and durability. The manufacturer's excellent brass construction makes it one of the best options for handloading this cartridge. Many shooters reload Lapua cases multiple times, which helps offset ammunition costs when you're running high volumes downrange.
Why does this come in a 10-round box instead of 20?
Lapua packages its Scenar and tactical loads in 10-round boxes to reflect the premium nature of match-grade ammunition. This smaller packaging is common with competition and professional-grade loads where quality control and consistency take priority over bulk quantities. Each box is built around precision standards rather than standard commercial box sizes.
What effective range should I expect from this load?
The 300 grain HPBT at 2723 fps excels beyond 1,000 yards, with realistic accuracy out to 1,500+ yards depending on your rifle, skill, and wind conditions. The flat trajectory and energy retention of the heavier bullet make it one of the best factory loads available for extended-range precision shooting. Your actual effective range will depend on your specific rifle and optics setup.
