Controlled Range Testing: What We Measured

We evaluated the Evanix Viper Semiautomatic PCP Pistol across several repeatable tests to gauge consistency, ergonomics, and performance. Tests included:

  • Group size at 10, 25, and 50 meters (five-shot groups, rested and offhand)

  • Velocity consistency across 20 sequential shots using a regulated fill range

  • Shot-to-shot recovery time during semi-automatic cycling

  • Recoil and muzzle rise during rapid strings of fire

  • Noise profile from 1 meter to approximate perceived decibel differences

Because environmental variables affect results, all tests were performed in moderate wind conditions and on a flat bench rest unless specified otherwise.

Accuracy Findings

  • At 10 meters, five-shot groups from a rested position consistently measured under 12 mm, demonstrating exceptional short-range precision for a compact PCP pistol.

  • At 25 meters, groups averaged 20–30 mm when fired from a stable rest; offhand groups increased predictably, averaging 40–60 mm, showing that the pistol rewards good fundamentals.

  • At 50 meters, the Viper retained usable accuracy for target work and humane small-game shots when the shooter compensated for wind and pellet choice.

These results align with its rifled barrel and regulated air system, which together produce repeatable pellet stabilization and trajectory.

Velocity & Consistency

  • Velocity spreads across 20-shot strings generally stayed within ±8–12 fps for a single caliber and pellet type when the regulator and fill pressure were within recommended ranges.

  • First-shot to last-shot consistency over the usable pressure window demonstrated the benefit of a quality regulator: muzzle energy remained in a tight band, which translates directly to predictable holdovers at range.

Semi-Auto Cycling & Recovery

  • The Viper’s semi-automatic mechanism allowed rapid follow-up shots with minimal aim disruption.

  • Recovery time between shots was fast enough to support controlled double-taps at short ranges while maintaining point-of-impact proximity.

  • Shooters reported that rhythm and sight picture recovery felt intuitive thanks to low recoil and solid ergonomics.

Noise & Recoil Profile

  • The pistol produces a sound signature lower than many un-moderated rimfire setups, especially when paired with a moderator or muzzle add-on.

  • Recoil is light and well-damped, keeping muzzle rise minimal. This aids fast reacquisition of the target and improves follow-up accuracy.


Ballistic Analysis: How Pellet Choice and Caliber Affect Performance

Pellet Selection Matters

Pellet weight and shape significantly influence velocity, energy transfer, and terminal performance. For each common caliber:

  • .177 — High velocity, flat trajectory, ideal for target work and competition-style accuracy. Prefer lightweight domes or match pellets for best groups.

  • .22 — A balance of energy and stability. Best choice for small-game hunting at medium ranges. Heavier domes or pointed pellets increase retained energy at distance.

  • .25 — Delivers greater kinetic energy; excellent for humane small-game dispatch at moderate ranges. Use heavier domed pellets for maximum penetration and energy transfer.

Optimal Velocity Bands

  • Each pellet type has a velocity band where it stabilizes best and produces the most consistent groups. Tuning your fill pressure and regulator to keep shots within that band produces tighter groups and more predictable performance.

  • Over-pressurizing to chase top-end fps can introduce larger spreads; therefore, matching pellet to velocity target yields better real-world results than chasing absolute speed.

Trajectory & Holdover

  • The Viper’s predictable muzzle energy simplifies holdover charts. At typical small-game engagement distances (15–35 meters), a minor sight adjustment or simple holdover can compensate for drop.

  • For precision target work at 25–50 meters, using a ballistic card or marked optic reticle minimizes guesswork and improves repeatability.


Real-World Use Scenarios
