Description

Heavy by Design. Stable by Structure.

The 300-grain Gold Country Rhino is not a compromise bullet.

It exists for shooters who need maximum mass, predictable penetration, and structural integrity across a wide range of impact energies — especially in platforms where lighter bullets lose momentum too quickly or fail structurally.

This bullet does not chase expansion.
It delivers crush, continuity, and control.

---

Wide Flat Nose, Real Work

The Rhino’s exposed lead wide flat nose is designed to displace material immediately on contact, creating a broad, straight crush path rather than a delayed or cosmetic mushroom.

This design favors:

• Immediate tissue disruption

• Straight-line penetration

• Consistent performance through mixed resistance

There are no polymer tips.
No thin jackets.
No velocity tricks.

Just mass and structure doing their job.

Shared Rhino Jacket Architecture

The 300-grain Rhino uses the same thick, mechanically supported copper jacket found throughout the Rhino Bullet System.

That jacket was engineered to remain intact under elevated impact velocities and heavy resistance — maintaining mass and directional stability where lighter or thinner designs fail.

This is why Rhino bullets perform consistently across:

• Handguns

• Lever-action rifles

• High-energy straight-wall and magnum platforms

Weight changes the momentum.
The behavior stays the same.

---

Cannelured, Flat Base, Hand-Swaged

The Rhino’s cannelure ensures secure seating and reliable retention under recoil and tubular magazine use.

The flat base contributes to consistent ignition and stability, especially in shorter barrels and heavy-for-caliber loads.

Each bullet is hand swaged, delivering:

• Uniform jacket concentricity

• Consistent core placement

• Repeatable weight and balance

This is match-grade construction applied to a working bullet.

Who This Bullet Is For

The 300-grain Rhino is ideal for shooters who prioritize:

• Deep, straight-line penetration

• Heavy bullet momentum

• Reliable performance across platforms

• Predictable terminal behavior over dramatic expansion

If you already know why you want 300 grains in .429 — this bullet solves the problem without explanation.
