Product Overview — Purpose-Built Magnum Performance

The .454 Casull is a true magnum cartridge designed to deliver significantly greater muzzle energy than typical handgun calibers.

Terminal Performance — Controlled Expansion & Deep Penetration

The 300-grain Jacketed Soft Point bullet is engineered to expand upon impact while preserving mass for deep penetration into vitals. This balance makes the round ideal for ethical harvesting of medium to large game at appropriate ranges and for defensive scenarios where deep, reliable penetration is required. Expect the JSP profile to produce controlled mushrooming that helps transfer energy effectively while reducing the likelihood of excessive fragmentation or inadequate penetration.

Note: Actual expansion, penetration, and point-of-impact vary with barrel length, shot placement, and target composition. Always test loads in your firearm to determine ballistic performance and effective range.
