Description

WHAT this bullet is

The Rhino 139-grain Flat-Nose is a heavy-for-caliber .284-diameter bullet engineered specifically for the 7-30 Waters, where bullet length, nose geometry, and bearing surface must work together to maintain safe feeding, stable pressure, and predictable field performance in lever-action rifles.

This is not a shortened spitzer.
It is not a generic 7mm bullet adapted after the fact.

It is a lever-gun bullet designed from the start for the mechanical realities of the 7-30 Waters.

WHO this bullet is for

This bullet is intended for shooters who:

• Run 7-30 Waters in lever-action rifles

• Prefer heavier bullets for penetration and momentum

• Hunt deer and similar game in woods or broken terrain

• Want safe tube-magazine feeding without pressure surprises

• Value predictable behavior over theoretical BC numbers

This bullet is for hunters who want the cartridge to behave consistently, not be pushed outside its design envelope.

---

WHERE it performs best

• Tube-fed lever-action rifles

• Classic and carbine-length barrels

• Woods hunting and practical field distances

• Situations where deep, straight penetration matters

---

WHY this bullet exists

Most modern .284 bullets are built for bolt guns, long throats, and pointed profiles.

In the 7-30 Waters, those designs introduce real problems:

• Unsafe nose-to-primer contact in tube magazines

• Erratic feeding geometry

• Unpredictable pressure behavior

• Reduced accuracy at realistic hunting distances

The Rhino 139 FN exists to eliminate those failure points entirely.

---

WHY this nose shape matters

Unlike legacy blunt flat-nose bullets, this Rhino uses a long, low-drag ogive that is deliberately shortened at the tip to form a true flat nose.

The result:

• Absolute tube-magazine safety

• Smooth feeding through the 7-30 Waters action

• Better downrange efficiency than traditional FN designs

• No compromise to cartridge safety or reliability

This geometry is intentional — and visible.

---

WHY 139 grains works in the 7-30 Waters

At 139 grains, this bullet occupies the heavier end of the cartridge’s functional window:

• Increased sectional density for penetration

• Stable performance across common 7-30 Waters twist rates

• Balanced velocity without forcing pressure

• Excellent behavior from short and mid-length barrels

This weight favors controlled penetration and momentum, not speed for its own sake.

---

HOW it is constructed

• Copper jacket over a soft lead core

• Cannelure positioned for proper crimping and ignition

• Flat base for stable pressure curves and consistent ignition

• Hand-swaged construction for concentricity and repeatability

Every design choice supports feeding reliability, pressure stability, and predictable terminal behavior.

---

HOW it behaves on impact

The flat-nose, soft-lead design delivers reliable energy transfer at realistic 7-30 Waters velocities.

There are:

• No polymer tips to fail

• No delayed-expansion gimmicks

• No dependency on excessive speed

Just consistent penetration and honest terminal performance where the cartridge was always meant to work.

WHERE this bullet fits in the Gold Country system

This bullet directly reflects principles outlined in:

• Gold Country Bullet Systems

• Gold Country Ammunition Systems

• Lever-Gun Fundamentals — Geometry, Safety & Feeding Reality

• Lever-Gun Bullet Geometry — Technical Note

Those documents exist because bullets like this follow the rules — not because they ignore them.

---

WHEN to choose the 139-grain over lighter options

Choose this bullet if you want:

• More penetration than 120-grain options

• Heavier impact behavior

• A steadier bullet for closer-range work

• Traditional lever-gun performance with modern consistency

If you want flatter trajectory or lighter recoil, the 120-grain exists for that reason.
