Desert Tech DTM Ammo Case 338LM 300GR 200rd

Product Description

The Desert Tech DTM Ammo Case 338LM 300GR 200rd is a factory-loaded 338 Lapua Magnum cartridge designed for long-range precision rifle shooting. This case delivers 200 rounds of 300-grain ammunition from Desert Tech, the same manufacturer known for their bullpup precision rifles.

338 Lapua Magnum is a full-power magnum cartridge built for extreme distance work. The round operates at high chamber pressure and delivers flat trajectory and retained energy well past 1,000 yards. Shooters use 338 Lapua for competitive long-range disciplines, extended-range training, and hunting at distances where smaller calibers lose effectiveness.

The 300-grain projectile weight is a common middle ground in 338 Lapua loadings. Heavier than the 250-grain options and lighter than 285- or 300-grain match projectiles, a 300-grain bullet balances velocity with ballistic coefficient for predictable flight in varied conditions.

Who Shoots 338 Lapua Magnum

338 Lapua Magnum is not a general-purpose cartridge. The round requires a heavy bolt-action or semi-automatic rifle built to handle magnum case dimensions and chamber pressure. Recoil is substantial, and barrel life is shorter than smaller calibers.

Competitive shooters use 338 Lapua in extreme long-range matches where targets sit beyond 1,500 yards. The cartridge’s energy retention and wind-bucking ability make it a preferred choice when conditions are variable and targets are distant. Hunters working open country at extended ranges also choose 338 Lapua for large game when shot distances exceed what a 30-caliber magnum can reliably deliver.

Because the cartridge is expensive to shoot and purpose-built for distance, it is less common than 6.5 Creedmoor or 308 Winchester. Shooters who own a 338 Lapum rifle typically buy ammunition in bulk to offset per-round cost and to develop reliable data with a single lot.

What to Confirm Before You Order

The product name and attributes do not specify the projectile design, whether the bullet is a hollow-point boat-tail match projectile, a solid copper design, or another construction. That information matters for ballistic performance and terminal effect. Call 817-393-4000 to confirm the exact bullet type and whether the load matches your rifle’s chamber and intended use.

Case quantity of 200 rounds is larger than a standard 20-round box but smaller than some bulk rifle packs. Verify packaging format if you need individual boxes or prefer a single sealed case.

Frequently Asked Questions

Q: What rifles chamber 338 Lapua Magnum?

A: 338 Lapua Magnum requires a rifle action specifically designed for magnum-length cartridges with a case head diameter larger than standard 308-based rounds. Bolt-action rifles from manufacturers like Desert Tech, Accuracy International, and Savage offer 338 Lapua chambers, and a few semi-automatic platforms exist. Your rifle’s manual or chamber stamp will confirm compatibility.

Q: Is 300-grain the best bullet weight for 338 Lapua?

A: 300-grain projectiles are a versatile middle weight for 338 Lapua, balancing velocity and ballistic coefficient for long-range shooting. Lighter bullets like 250-grain loads offer higher muzzle velocity and flatter trajectory at closer distances, while heavier 285- to 300-grain match bullets maximize ballistic coefficient for extreme range. The best choice depends on your distance, wind conditions, and rifle twist rate.

Q: Does Desert Tech make their own ammunition?

A: Desert Tech manufactures precision rifles and also produces factory-loaded ammunition under the DTM line. The DTM product line is designed to pair with their rifle platforms, though the ammunition works in any rifle chambered for the same cartridge. Call 817-393-4000 to confirm the exact specifications of this DTM load.

Q: How much does 338 Lapua Magnum cost per round?

A: 338 Lapua Magnum is one of the more expensive rifle cartridges due to case capacity, powder charge, and projectile weight. Per-round cost varies by manufacturer, bullet type, and order quantity. Buying in larger case quantities typically reduces cost per shot. Contact Western Sport at 817-393-4000 for current pricing on this 200-round case and any quantity discounts.

Q: Can I order ammunition online and have it shipped to Texas?

A: Texas law allows ammunition to be shipped directly to your address without an FFL transfer. Ordering policies and carrier restrictions vary, so call Western Sport at 817-393-4000 to confirm the ordering process, shipping options, and any requirements for this product.

Q: What is the shelf life of rifle ammunition?

A: Factory-loaded rifle ammunition stored in a cool, dry environment away from temperature swings and humidity can remain reliable for decades. Avoid exposing cartridges to moisture, solvents, or extreme heat. Inspect primers and case mouths for corrosion before use, and discard any round showing visible damage or discoloration.
