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.
