Purpose
This tool compares two loads side-by-side, showing drop, velocity, energy, wind drift, and flight time at 100-yard intervals. Use it to evaluate which load performs better for your needs.
Inputs
Weight (grains): Bullet weight. Required for energy calculations.
BC: Ballistic Coefficient. Higher values mean better aerodynamics and less drop/drift.
Drag Model: G7 is recommended for modern boat-tail bullets. G1 for older flat-base bullets.
MV (fps): Muzzle velocity in feet per second.
Max Range: Maximum distance to simulate.
Results
Drop: Bullet drop below muzzle line. Units selectable: MOA, MRAD, or inches.
Velocity (fps): Remaining bullet velocity at that range.
Energy (ft-lb): Kinetic energy at that range.
Wind Drift: Wind deflection with 10 mph crosswind from 3 o'clock. Units selectable: MOA, MRAD, or inches.
Time: Flight time in seconds to reach that range. Lower = faster bullet.
B2 Advantage: Percentage showing how much better (+) or worse (-) Bullet 2 is. Green = B2 is better, Red = B2 is worse.
Simulation Details
Conditions: Standard atmosphere (59°F, sea level, 50% humidity).
Wind: 10 mph crosswind from 3 o'clock direction.
Launch: Horizontal fire from muzzle (no zero, no scope height).
Spin Effects: Disabled for simplified comparison.
Accuracy Note: Simulation accuracy degrades at longer ranges, longer flight times, and with atypical bullet parameters (unusual BCs, extreme velocities, etc). Use results for relative comparison rather than absolute predictions.
