Caliber

Filter by Use

Ammunition Load

Use Custom Ballistic Data

Barrel Length (inches)

7.5" to 30" supported with caliber-specific velocity adjustment

Zero Distance (yards)

🌀 Barrel Twist Rate

Select your barrel's twist rate for accurate spin drift calculation

Scope Height (inches above bore)

Typical AR-15: 1.5" | High mount: 2.0" | Bolt gun: 1.5"

Target Distance (yards)

Slope Angle (degrees) - Optional

+ = uphill | - = downhill | Use M Reticle to measure automatically

Target Size (for hit probability)

🎯 Target Speed (mph) Optional - for moving targets

Walking: 3-4 | Running: 8-15 | Vehicle: 20-35 mph (HSS reticle stadia)

M Reticle: Uses phone camera + sensors to measure angle, heading, and get weather.

Temperature (°F)

Humidity (%)

Elevation (feet MSL)

Sea level to 20,000 ft supported

Station Pressure (inHg) Optional - for Kestrel users

Leave blank to calculate from elevation. Enter actual reading for maximum accuracy.

Wind Speed (mph)

Wind Direction (degrees)

0°=Headwind | 90°=From Right (hold R) | 180°=Tailwind | 270°=From Left (hold L)
