Ultrmax Ammunition
The Ultramax 338 Arc 300-grain HPBTM is a centerfire rifle round engineered for shooters and hunters who've adopted the modern 338 Arc platform. This cartridge delivers the proven stopping power of a 300-grain projectile in a package designed to function reliably in 338 Arc–chambered rifles. Whether you're building a truck gun, testing a new platform, or stocking up for the range, Ultramax ammunition offers a consistent, straightforward option for 338 Arc shooters who want quality factory rounds without the premium price tag.
The 300-grain hollow-point boat-tail (HPBTM) design is a classic choice for centerfire rifle applications. Boat-tail projectiles are known for better aerodynamic performance downrange compared to flat-based alternatives, which translates to flatter trajectories and more predictable wind drift characteristics at distance. The hollow-point construction supports controlled expansion, making this load suitable for hunting applications where you need reliable terminal performance.
Ultramax delivers this ammunition in convenient 20-round boxes, with 10 boxes per case, so you can order in bulk or grab a single box for the range. That modular packaging gives you flexibility whether you're a high-volume shooter, a hunter building a field load, or someone just getting started with the 338 Arc. Each round is manufactured to function in standard 338 Arc chambers, so compatibility is straightforward if you're already running this cartridge.
