HSM 454 Casull 300gr JSP Ammunition - 20 Rounds Pro Pistol

The HSM 454C5N20 Pro Pistol ammunition delivers maximum stopping power for hunters and shooters demanding premium performance from their .454 Casull revolvers. This heavy-grain load combines a 300-grain jacketed soft point bullet with HSM's precision manufacturing standards. Each cartridge provides consistent expansion and deep penetration for large game hunting and demanding applications.

What Makes This Different

HSM's Pro Pistol line features match-grade components and strict quality control that surpasses standard factory ammunition. The 300-grain jacketed soft point bullet expands reliably while maintaining structural integrity for maximum energy transfer. Unlike lighter .454 Casull loads, this heavy-grain configuration maximizes the cartridge's potential energy, delivering approximately 1,625 ft-lbs of muzzle energy from typical 7.5-inch barrels.

Key Features

• 300-grain jacketed soft point bullet for controlled expansion and deep penetration
• Premium brass cases with consistent wall thickness for reliable extraction
• Match-grade powder charges for velocity consistency shot-to-shot
• Boxer-primed cases suitable for reloading applications
• 20-round box packaging with individual cartridge protection
• Compatible with all .454 Casull revolvers including Ruger Super Redhawk and Freedom Arms models
• Muzzle velocity approximately 1,200 fps from 7.5-inch barrels

This ammunition excels in hunting applications where deep penetration matters most. The 300-grain bullet retains momentum through heavy bone and muscle, making it effective on elk, bear, and other large North American game. The jacketed soft point design initiates expansion upon impact while the heavy bullet weight ensures straight-line penetration. Shooters report consistent accuracy from quality revolvers, with groups typically measuring 2-3 inches at 50 yards.
