The Hornady Custom Ammunition 454 Casull 300 Grain XTP Jacketed Hollow Point round brings proven stopping power to a cartridge built for hunters and handgun enthusiasts who demand serious capability. This 20-round box pairs Hornady's own-manufactured brass with precision components engineered for reliability and consistency, making it a solid choice for hunters running large-frame revolvers and those preparing for maximum-power handgun hunting or defensive scenarios where the .454 Casull's considerable energy is the point.
Hornady manufactures the brass in their Custom line to exacting standards—each case is selected or produced for reliable feeding, corrosion resistance, proper hardness, and the ability to handle the peak pressures the .454 Casull generates. Powders are matched to each load to deliver optimal pressure and velocity while maintaining lot-to-lot consistency, and primers are chosen to ignite the charge quickly and reliably. The result is ammunition you can depend on when it counts.
The 300 Grain XTP (eXtreme Terminal Performance) bullet is a jacketed hollow point engineered to expand reliably across a range of velocities typical of .454 Casull handloads. This weight and bullet combination makes sense for hunters taking medium to large game at moderate distances or for anyone who relies on this cartridge for protection. Hornady has spent decades refining the XTP design, and it remains one of the most proven hunting and defense bullets available for magnum revolvers.
If you shoot a large-frame revolver chambered in .454 Casull, you already know this isn't a casual range round—it's ammunition for serious hunting and defense work. Hornady Custom delivers the consistent, hard-hitting performance you need without the premium cost of match-grade specialty ammo.
| Cartridge | .454 Casull |
| Bullet Weight | 300 Grain |
| Bullet Type | XTP Jacketed Hollow Point |
| Rounds Per Box | 20 |
| Manufacturer | Hornady |
This round is chambered in .454 Casull, so it will fire only in large-frame revolvers and other firearms specifically marked for that cartridge. Always verify your firearm's chambering before loading or firing any ammunition.
Hornady manufactures the brass in this Custom line with reloading in mind. The cases are produced to proper specifications for hardness and longevity, making them suitable for reloading after the first firing. Check Hornady's reloading manual for load data specific to .454 Casull.
XTP stands for eXtreme Terminal Performance. The XTP is a jacketed hollow point bullet designed to expand reliably when it strikes game or a target, creating a larger wound channel than a solid bullet of the same weight. The 300 Grain XTP in this load is a proven choice for hunting applications where the .454 Casull's power is leveraged for medium to large game at moderate ranges.
This is a 20-round box, which is standard packaging for Hornady Custom handgun ammunition.
