The Underwood Xtreme Hunter is purpose-built for serious big game hunters who demand maximum penetration and stopping power. Loaded to +P pressure, this 325-grain copper solid projectile achieves what hollow points can't match – an enormous permanent wound cavity combined with complete barrier penetration. You get deep, predictable performance whether you're hunting thick-bodied game or dealing with heavy vegetation between you and your target.
Instead of relying on expansion to create wound channels, the Xtreme Hunter uses a solid copper bullet with optimized nose geometry to generate massive hydrostatic shock. This monolithic construction means no jacket separation, no fragmentation concerns, and terminal performance that holds up even when shooting through bone or hide. The result is consistent, devastating effectiveness that pure hollow points simply can't match in penetration depth.
When you're hunting in low light or pre-dawn conditions, traditional powder can blind you on the shot. Underwood's flash-suppressed formulation keeps your vision intact so you can spot impact and make follow-up shots if needed. Combined with the nickel-plated brass cases that resist corrosion and provide smooth, reliable feeding, this is ammunition built for real-world hunting conditions.
The 2275 fps muzzle velocity with 3736 ft-lbs of energy puts serious power downrange – enough velocity to carry that heavy 325-grain bullet effectively at hunting distances. The 20-round box format keeps costs reasonable while giving you enough rounds to test your rifle's accuracy before the season starts. Load them in your Marlin 1895, lever-action rifle, or modern single-shot and you've got a load that will handle whatever you encounter in the field.
The +P designation means this load is loaded to higher pressure than standard 45-70 ammunition. It's designed for modern firearms in good condition. Older rifles like Trapdoor Springfields or early production guns may not be suitable. Check that your rifle is specifically rated for modern +P loads, or have a gunsmith verify your firearm's condition before use.
Yes, the 325-grain bullet is made entirely of copper with no lead content, making it environmentally friendly and legal for use in areas with lead ammunition restrictions. However, you should always verify your specific hunting location's ammunition requirements before purchasing.
The monolithic copper design creates a much larger permanent wound channel than expanding hollow points without relying on expansion. It maintains performance even when passing through heavy bone or barriers, delivering deep, consistent penetration that stops game reliably. This makes it especially effective for thick-skinned or heavily built game.
Yes, the nickel-plated brass cases are boxer-primed and fully reloadable. The nickel plating offers corrosion resistance and easier extraction compared to traditional brass, making them good candidates for reloading if you want to reload your own ammunition.
