Fort Scott Munitions .338 Lapua Mag 250gr TUI Solid Copper Spun Ammo - 20 Rounds

Fort Scott Munitions .338 Lapua Mag 250gr TUI solid copper spun ammo delivers precision performance for long-range rifle shooters who demand reliable, consistent rounds. Built on Fort Scott's reputation for innovative ammunition engineering, this cartridge pairs a 250-grain solid copper projectile with their proprietary Tumble Upon Impact (TUI) design—a controlled-failure system engineered to fragment predictably on target rather than over-penetrate or deflect unpredictably. The .338 Lapua Mag is the go-to cartridge for extreme-distance hunting and precision rifle competition, where wind drift matters and every shot counts.

The solid copper construction eliminates traditional lead cores, offering a cleaner shooting experience and compliance with non-toxic ammunition standards in sensitive areas. Fort Scott's manufacturing precision ensures that each round meets strict quality control, so you get consistent velocity and point-of-impact shot to shot—critical for dialing in at distance and maintaining zero across multiple sessions. Whether you're stretching your effective range on big game or pushing your marksmanship skills at a long-range competition, this ammunition is built to perform when conditions and targets demand the best.

Packaged in convenient 20-round boxes, Fort Scott Munitions .338 Lapua Mag ammo integrates easily into your reloading or pre-loaded ammunition rotation. The .338 Lapua's flat trajectory and retained energy make it a favorite among serious shooters who refuse to compromise on consistency or terminal performance. This is ammunition engineered by shooters for shooters.

Frequently Asked Questions

What is Tumble Upon Impact (TUI) and how does it work?

TUI is Fort Scott Munitions' controlled-failure bullet design. The projectile is engineered to tumble and fragment upon impact in soft tissue, delivering reliable energy transfer while minimizing over-penetration. This design promotes more predictable wound channels and reduced risk of uncontrolled deflection compared to traditional solid-core bullets.

Is this ammo suitable for long-range hunting?

Yes. The .338 Lapua Mag is purpose-built for extreme-distance hunting and precision rifle applications. The 250-grain bullet weight and flat trajectory make it well-suited for long-range game. Fort Scott's quality control ensures the shot-to-shot consistency required for reliable performance at distance.

Can I use this ammunition in competition or at the range?

Absolutely. The .338 Lapua Mag is widely used in long-range precision rifle competitions and training. The consistent manufacturing means you'll get reliable velocity and ballistics for load development, zero confirmation, and practice sessions.

Why choose solid copper ammunition?

Solid copper construction eliminates lead, which is required in many hunting areas and ranges with environmental restrictions. It also provides consistent velocity and performance while supporting cleaner shooting practices. Fort Scott's solid copper spun bullets are manufactured to the same precision standards as their traditional designs.
