The Burris Eliminator III and Eliminator 5 represent the pinnacle of integrated riflescope technology, combining a high-quality laser rangefinder with a sophisticated internal ballistic computer. By calculating the exact trajectory of your bullet in real-time, these optics allow shooters to range, aim, and engage targets with confidence, virtually eliminating the need for manual holdover calculations or complex scope turret adjustments in the field. This calculator serves as your primary bridge between your specific ammunition’s performance and your optic’s digital brain, ensuring your programmed Drop Number and BC Correction are optimized for precision.

Comprehensive Guide: Programming Your Eliminator
To ensure your Eliminator scope provides accurate holdovers at distance, you must correctly translate your ballistic data into the scope’s proprietary programming language.
1. Preparing Your Ballistic Profile
Accuracy starts with high-quality data. Before inputting values into your scope, ensure you have the following information:
- Muzzle Velocity (fps): This is the speed at which your bullet exits the muzzle. Because velocity fluctuates with barrel length and ambient temperature, using a chronograph for this measurement is highly recommended for long-range reliability.
- Ballistic Coefficient (BC): This number describes your bullet’s ability to overcome air resistance. The Eliminator system uses this value to calculate how quickly your projectile slows down over time.
- Environmental Inputs: Altitude and temperature significantly affect air density. By providing these baseline conditions, you ensure the scope’s internal logic compensates correctly for the air through which your bullet will travel.
2. Interpreting the Programming Output
When you generate your data, the calculator provides two critical values for the Eliminator settings:
- Drop Number: This is the primary value the scope uses to map your trajectory. It essentially tells the scope how much your bullet drops relative to gravity at a specific reference distance.
- BC Correction: This value allows the scope to fine-tune its internal drag model. It ensures the reticle’s holdover point remains accurate as the bullet’s velocity bleeds off at longer ranges.
3. Pro-Tips for Field Success
- The “Zero” Baseline: Your Eliminator must be physically sighted in at 100 yards before you begin the digital programming process. The scope’s ballistic computer uses this 100-yard zero as the anchor for all future trajectory calculations.
- Verify at the Range: After programming your Drop Number, always verify the holdovers at known distances (e.g., 300, 500, and 700 yards). If you notice a consistent point of impact deviation, you may need to “tweak” your programmed Drop Number slightly until the laser-ranged holdover matches your actual bullet strike.
- Battery Maintenance: These scopes rely on their internal computers for ballistic calculations. Always carry a spare battery, especially for extended backcountry hunts where the scope’s laser and processing power are your primary tools for precision.
Pro-Tip: If you are transitioning between different ammunition types, you can save separate “Ballistic Profiles” if your specific Eliminator model supports it. Simply re-run this calculator with your new load’s data and update the Drop Number in your scope settings to match.
