Hornady Custom .454 Casull 300 Grain XTP Mag ammunition is built for shooters who demand serious performance from one of the most powerful handgun cartridges available. Designed around Hornady’s proven XTP Mag bullet, this 20-round load combines dependable factory consistency with the rugged construction and controlled performance Hornady ammunition is known for.
At the heart of every cartridge is a 300-grain XTP Mag bullet engineered specifically for the demanding pressures and velocities associated with the .454 Casull. The XTP Mag design features a tough, controlled-expansion construction that’s built to handle the higher velocities generated by magnum handgun cartridges while maintaining structural integrity. With a sectional density of .210 and a ballistic coefficient of .180 (G1), the bullet is designed to deliver a strong combination of accuracy, penetration, and terminal performance.
Hornady Custom ammunition is manufactured with the same attention to detail that serious shooters have come to expect from the Hornady name. Every round is hand-inspected before packaging, helping ensure consistent quality from cartridge to cartridge. Hornady produces most of the brass used in its Custom handgun ammunition, while carefully selected components are used where applicable to meet demanding standards for reliable function, corrosion resistance, proper hardness, and the ability to withstand maximum chamber pressures.
The powder charge is carefully matched to the cartridge and bullet combination to provide consistent pressure, velocity, and performance from lot to lot. Primers are individually matched to each load and selected for their ability to ignite the powder charge quickly, completely, and reliably. The result is factory-loaded ammunition designed to deliver the consistency shooters expect without having to assemble their own handloads.
From a 7.5-inch barrel, this load is listed at a muzzle velocity of 1,650 feet per second with 1,813 foot-pounds of energy, making it a substantial option for the .454 Casull platform. Hornady lists the load for applications ranging from medium game and large game to personal defense, giving experienced shooters a versatile option when substantial handgun performance is required.
Each box contains 20 rounds of Hornady Custom .454 Casull ammunition loaded with 300-grain XTP Mag bullets. For shooters who appreciate premium components, rigorous quality control, and hard-hitting magnum performance, this Hornady load brings serious capability to the range or field.
