Underwood Ammunition 460 S&W Magnum 250 Grain Lehigh Xtreme Penetrator Lead-Free Box of 20

Underwood Ammunition 460 S&W Magnum 250 Grain Lehigh Xtreme Penetrator Lead-Free Box of 20 uses a solid-copper, non-expanding bullet built for maximum penetration in dangerous-game situations. The fluted nose displaces tissue outward as it travels. This gives a large, permanent wound channel without any risk of jacket separation. Underwood drives this 250 grain bullet to a high velocity that few factory loads in this caliber can match.

Solid-Copper Dangerous-Game Penetration

As a result, backcountry hunters who need reliable penetration against bear or large hogs often choose this loading. The lead-free build also avoids fragmentation, which keeps the wound channel straight and predictable at any range or angle of impact. Meanwhile, Underwood loads each cartridge to take full advantage of the 460’s massive case capacity.
