Description

Functional Identity

The Gold Country Viper 140-grain .284 bullet is a spitzer lead-tip, low-drag precision projectile engineered for shooters who prioritize trajectory efficiency, wind resistance, and consistent external ballistics across medium-to-long-range distances.

This bullet is flight-biased by design.
It is not intended to manage terminal mechanics — it is intended to arrive precisely where calculated.

Why This Bullet Exists

The 140-grain weight has long been the reference point for 7mm cartridges. However, many traditional 140-grain hunting bullets sacrifice aerodynamic efficiency, while modern match bullets often abandon real-world practicality.

The Viper 140 exists to occupy the precision middle ground.

It provides:

• Flatter trajectories than traditional soft points

• Lower wind drift without stepping into ULD specialization

• Consistent ballistic behavior across varied barrel lengths

• A lead-tip spitzer profile that balances efficiency and manufacturability

This bullet favors predictable flight, not terminal optimization.

Bullet System — Gold Country Viper

The Viper Bullet System is designed around aerodynamic efficiency and repeatable precision.

Key design characteristics include:

• Spitzer lead-tip profile for reduced drag

• Optimized ogive geometry for stable long-range flight

• Flat-base construction for consistent launch behavior

• Uniform copper jacket

• Soft lead core

• Hand-swaged concentricity for accuracy consistency

The Viper system emphasizes external ballistic control, not expansion or penetration mechanics.

Ballistic Coefficient (Estimated)

Based on spitzer lead-tip geometry, ogive length, and flat-base construction, the Viper 140 falls into a high-efficiency class for practical 7mm bullets.

Estimated ballistic coefficients:

• Estimated G1 BC: ~0.535 – 0.565

• Estimated G7 BC: ~0.270 – 0.290

These values reflect a bullet optimized for wind resistance and vertical consistency, not extreme long-range ULD performance.

Actual BC values may vary slightly with jacket and tip uniformity.

This Bullet’s Primary Platform Usage

The Viper 140-grain .284 is best suited for modern bolt-action and single-feed platforms where trajectory control and ballistic efficiency matter most.

Primary Platforms

• 7mm-08 Remington
  A precision-friendly option where moderate velocity benefits from efficient flight behavior.

• .280 Remington / .280 Ackley Improved
  A natural pairing for flat trajectories and repeatable long-range solutions.

• 7mm Remington Magnum
  Well-suited for extended-distance shooting where wind drift becomes a factor.

• 7×57 Mauser (modern actions)
  For shooters prioritizing ballistic efficiency over terminal expansion in legacy-based platforms.

This bullet is intended for precision shooting and trajectory-focused hunting, where flight efficiency outweighs terminal mechanics.

IMPORTANT NOTE — Not for Tube-Feed Use

This bullet uses a spitzer lead-tip profile and is not safe for use in tubular magazines.

Do not use this bullet in tube-fed rifle platforms.

Design Focus Clarification

The Gold Country Viper system is engineered around external ballistic efficiency and trajectory consistency.

It prioritizes:

• low drag flight behavior

• wind resistance at distance

• repeatable ballistic prediction

While capable of effective terminal performance, the Viper design does not center on engineered expansion timing, mass-driven penetration, or extreme ULD specialization.

Its role is precision flight — allowing shooters to place shots accurately and predictably at distance.
