Remington Ammo Ballistics Calculator

Precision shooting requires more than just knowing your drop; it requires an understanding of the environment. This advanced ballistics tool is designed to give hunters and long-range shooters a comprehensive view of their cartridge’s flight path. Featuring built-in factory data for classic Remington Core-Lokt loads, this calculator estimates bullet drop, retained velocity, kinetic energy, and lateral wind drift. Dial in your environmentals and take the guesswork out of your next shot.

How to Use This Tool

To generate your custom trajectory table, you can either select a pre-loaded cartridge or manually enter your own custom ballistics data.

• Cartridge Preset: Use the dropdown menu to quickly load factory data for common rounds (like the .30-06 Springfield or 6.5 Creedmoor). Selecting a preset will automatically fill in the Muzzle Velocity, Bullet Weight, and Ballistic Coefficient. If you handload or use different ammo, leave this on “Custom” and fill in the fields below manually.
• Muzzle Velocity (fps): The speed of the bullet as it leaves the muzzle.
• Bullet Weight (gr): The physical weight of the projectile in grains.
• Ballistic Coefficient (G1): The aerodynamic drag rating of your bullet.
• Zero Range (yds): The exact distance at which your optic is sighted in to hit dead center.
• Sight Height (in): The distance from the center of your rifle’s bore to the center of your scope tube (1.5 inches is standard for many hunting rifles).
• Wind Speed (mph): The estimated speed of the crosswind.
• Wind Angle (deg): The direction the wind is blowing from relative to your barrel. (A 90-degree wind is a full lateral crosswind, while 0 degrees is a straight headwind).

Once your data is locked in, click Generate Trajectory Data to map your shot.

Understanding Your Tactical Data

The calculator outputs your bullet’s performance in precise 50-yard increments up to 500 yards. Here is how to read your data:

• Range (yds): The distance to your target.
• Drop (in): How far the bullet falls below your line of sight. At your Zero Range, this will read 0.0. Negative numbers indicate bullet drop, meaning you need to hold your reticle high or dial your elevation turret up.
• Wind Drift (in): How far the crosswind pushes your bullet horizontally off target. You will need to hold into the wind by this exact amount to compensate.
• Velocity (fps): The remaining speed of the projectile.
• Energy (ft-lbs): The kinetic energy delivered on impact, a critical metric for ensuring ethical terminal performance on medium to large game.
