Underwood 454 Casull 250gr - Xtreme Penetrator 20rd 10bx/cs

The Underwood 454 Casull 250gr Xtreme Penetrator ammunition is purpose-built for hunters, sport shooters, and defensive carry users who demand deep, reliable penetration from the most powerful handgun cartridge in common use. This big-bore round is engineered for maximum stopping power and barrier performance in scenarios where conventional ammunition may fall short—from dangerous game hunting to worst-case personal defense situations. Each 20-round box delivers factory-loaded consistency that law enforcement and tactical professionals rely on when margin for error is zero.

The 250-grain Xtreme Penetrator projectile is specifically designed to maximize penetration depth while maintaining bullet integrity through tough barriers—bone, vehicle glass, and heavy clothing. Underwood's precision loading ensures consistent velocities and pressure curves that unlock the full potential of the 454 Casull case without inducing dangerous pressure spikes. The hardened-steel construction of the bullet resists deformation, making it ideal for situations requiring straight-line performance rather than rapid expansion. This ammunition is loaded to near-maximum pressures, delivering hard-hitting ballistics that separate it from standard factory loads.

Shooters operating Ruger Super Redhawk, Freedom Arms, or other 454 Casull-rated revolvers will find this load suitable for field hunting, competition, and defensive carry in areas where handgun penetration is a primary concern. The 20-round per box format in a 10-box case (200 rounds total) supports range testing, load development, or stocking serious defensive reserves. Verify your firearm's specifications and rated pressure limits before use; the 454 Casull's powerful recoil and blast demand strong firearms and proper shooting technique.
