Performance Characteristics

The 430-grain hard cast projectile is designed for deep penetration and reliable expansion on medium to large game. The flat nose profile delivers excellent stopping power while the gas check prevents leading in the bore—critical for shooters who value accuracy and barrel longevity.

At 1925 fps, this load strikes a balance between velocity and controllability in lever-action rifles and modern single-shot platforms. The +P designation indicates this ammunition is loaded to higher pressures than standard 45-70 loads and should only be used in firearms designed to handle modern pressures.

Ideal For

• Hunting medium to large game
• Lever-action rifle enthusiasts
• Modern single-shot rifle shooters
• Handloaders seeking quality factory ammunition reference loads

Each box contains 20 rounds, packaged 10 boxes per case for convenient storage and transport.
