Heavy Penetration Load · Lever-Gun & Revolver Compatible

Functional Identity

This is a heavy .44 Remington Magnum ammunition load built around the Gold Country Rhino Power Strike 300-grain flat-nose bullet, designed for deep, straight-line penetration and controlled crushing force.

It is manufactured by Gold Country Ammo using new components and assembled specifically for platforms that benefit from mass, momentum, and structural integrity rather than velocity-driven expansion.

Why This Load Exists

Lighter .44 Magnum loads rely on speed to do the work.

This load relies on mass, shape, and structure.

The 300-grain Rhino Power Strike exists for shooters who want:

• Predictable penetration through resistance

• Consistent behavior across short and mid-length barrels

• Reliable feeding in lever-action rifles

• A load that performs the same way every time, not just under ideal conditions

This is a momentum-driven solution, not a velocity showcase.

Bullet System: Gold Country Rhino Power Strike

This load uses the Gold Country Rhino Power Strike 300-grain flat-nose bullet, a wide-meplat, exposed-lead design engineered for:

• Straight-line penetration

• Structural integrity under heavy resistance

• Magazine-safe geometry for tubular magazines

• Consistent ignition and crimp via cannelure

The bullet advances first — then crushes.
It does not depend on tip-initiated expansion.

---

Platform Behavior

This ammunition is suitable for:

• Lever-action rifles chambered in .44 Magnum

• Revolvers chambered in .44 Magnum

The heavier bullet weight and flat-nose geometry support reliable feeding and predictable performance in platforms where lighter, faster loads can behave erratically.
