Description
The DoubleTap DT Longrange represents what happens when a manufacturer focuses entirely on precision shooting. This load pairs a 300-grain hollow point boat tail bullet with carefully assembled brass cases, creating ammunition that's built to reward disciplined marksmanship.
The 300-grain weight sits at the sweet spot for extreme distance work with the .338 Lapua. Heavier than the traditional 250-grain loads you'll find elsewhere, this projectile carries significantly more momentum downrange, which means it resists wind drift better and maintains energy further out. The HPBT design itself is engineered for match-level consistency, with a concentric jacket wrapped around a precisely formed lead core. That boat tail design isn't just for looks either, it's angled to promote velocity retention and flatten your trajectory past what lighter bullets can manage.
DoubleTap's Precision Loading Process
DoubleTap loaded these rounds with the kind of attention to detail that separates match ammunition from everything else. Each cartridge uses non-corrosive, boxer-primed brass cases that are both reloadable and uniform enough to contribute to shot-to-shot consistency. The powder charges are weighed and measured to strict tolerances, which is how they achieve velocities of 2850 fps with the stability needed for grouping at 600 yards or beyond. This isn't fast and loose ammunition, it's engineered.
Real-World Performance at Distance
When you're shooting beyond 300 yards, the compromises inherent in general-purpose ammunition become obvious. This load doesn't ask you to compromise. The 300-grain projectile's ballistic coefficient means less drop, less wind deflection, and more predictability. At 1000 yards you're still carrying meaningful energy, and groups tend to stay tight when your rifle cooperates. Competition shooters and long-range discipline enthusiasts gravitate toward this load because it delivers what it promises.

Frequently Asked Questions
What makes the 300-grain bullet choice better for long-range than lighter options?
The 300-grain projectile carries more weight forward downrange, which resists wind deflection more effectively and retains energy further out than lighter bullets. For distance work beyond 600 yards, that extra mass translates to flatter trajectories and more predictable ballistics in variable wind conditions.
Can I reload DoubleTap brass cases?
Yes, these rounds use standard boxer-primed brass that's reloadable. The uniform case construction and consistent manufacturing mean the brass maintains its concentricity through multiple reloading cycles, which contributes to the consistency this ammunition is designed for.
Is this ammunition suitable for hunting, or is it match-only?
This load is engineered as match-grade ammunition and is best suited for precision shooting disciplines and range work. The hollow point boat tail design is optimized for ballistic consistency at distance rather than terminal performance on game animals.
How does the velocity of 2850 fps compare to other 338 Lapua loads?
At 2850 fps, this load sits in the standard range for heavy-bullet 338 Lapua ammunition. It prioritizes consistency and accuracy over velocity, meaning DoubleTap tuned the powder charge to deliver the ballistic performance needed at distance rather than pure speed off the muzzle.
