Description
The Barnes LRX in .338 Lapua Magnum is a 280-grain, all-copper bullet built for folks who load their own and want to stretch the legs of a big-bore magnum. With a long ogive, an extended boat tail, and a polymer tip, it carries a G1 ballistic coefficient of .667 and a .350 sectional density, which is exactly the kind of number you want when the wind picks up and the target is way out there. These are component bullets, so they're meant for handloading rather than ready-to-fire ammo.
What Sets the .338 LRX Apart
Barnes built the LRX line off the proven Tipped Triple-Shock platform, then stretched the ogive and boat tail to squeeze out more BC. The polymer tip does double duty: it sharpens the profile for better downrange flight and kicks off expansion the moment it hits. On impact the scored nose cavity peels back into four razor-sharp copper petals and roughly doubles in diameter, cutting a wide wound channel while the solid copper shank drives deep. Because there's no lead core to come apart, weight retention stays high and penetration is consistent shot after shot.
Reloading the 280-grain Barnes LRX
These measure .338 in diameter with a 1.864-inch bullet length and run best out of a 1:10 twist or faster, which covers just about any factory .338 Lapua barrel. The Accu-Groove rings machined into the shank are there to cut copper fouling and ease chamber pressure, so you spend less time scrubbing the bore and more time shooting. Barnes publishes solid load data for this bullet across popular slow-burning magnum powders like H1000, Retumbo, and RL-25, giving you a good starting point to develop an accurate node in your own rifle.
For long-range elk, moose, and other heavy game, this is a serious projectile. The combination of high BC, monolithic construction, and dependable expansion makes it a favorite among handloaders chasing both accuracy and clean, ethical kills at distance.

Frequently Asked Questions
Are the Barnes .338 Lapua LRX bullets loaded ammunition or component bullets?
These are component bullets for handloading, not loaded ammo. You'll need your own brass, primers, and powder to assemble finished cartridges. Barnes offers published load data for this 280-grain bullet to help you get started safely.
What twist rate do I need to stabilize the 280-grain .338 LRX?
Barnes recommends a 1:10 twist or faster for this bullet. That covers the vast majority of factory .338 Lapua Magnum rifles. If your barrel is a slower twist, you'll want to verify stability before committing to a load.
Why does the Barnes LRX have grooves cut into the shank?
Those are Barnes Accu-Groove rings, machined into the bearing surface to reduce copper fouling and relieve chamber pressure. The payoff is a cleaner bore and more consistent pressures from shot to shot. It's part of why monolithic Barnes bullets tend to shoot accurately without constant barrel scrubbing.
What game is the 280-grain .338 LRX best suited for?
This bullet shines on larger big game like elk, moose, and plains game, especially at longer ranges where its .667 ballistic coefficient really pays off. The all-copper construction gives high weight retention and deep penetration, with the polymer tip driving reliable expansion into four cutting petals. It's a strong choice for hunters who take ethical long-range shots.
