CaliberAtlas › Range Card Builder

Range Card / DOPE Card Generator

Build a printable range card (DOPE card) for any cartridge in the database. Pick a load and zero, choose MOA or MIL, and get a per-distance table of retained velocity, energy, bullet drop, and the calculated scope come-up to dial at each range — ready to print or export to PDF for the field.

"I've used Strelok Pro, Range Buddy, Nikon Spot-on and others. No longer. I'm sticking with yours. Absolutely fantastic parameters!" — Larry A., rimfire and PCC shooter, first week on CaliberAtlas

What a range card is

A range card, or DOPE (Data On Previous Engagements) card, lists the elevation and windage corrections needed to hit at each distance for a specific rifle, load, and zero. It's the reference a shooter dials or holds from in the field.

What the generator produces

• Range, retained velocity (fps), and energy (ft-lb) at each distance
• Bullet drop, elevation come-up in MOA or MIL, and the modeled turret clicks to dial
• Full-value wind holds, time of flight, and a transonic cutoff (~1,340 fps) beyond which drop predictions grow less reliable
• Three print formats: a full sheet, a 3×5 field card, and a buffer-tube strip — plus PDF export

True it to your rifle

No table is your rifle. Enter what your rifle actually did — the drop you observed at two or more distances — and the builder solves the muzzle velocity that best fits your observed elevation data, then rebuilds the card around that fitted velocity. It improves elevation prediction for that rifle, load, and condition set — it doesn't replace confirmation at distance, especially near or beyond transonic.

Precision inputs

• Custom conditions: temperature, altitude, pressure, and humidity (metric or imperial)
• Sight height, wind direction, incline angle, and a BC override for handloads
• Altitude card sets — print one card per elevation band to cover a hunt's density-altitude spread
• Save cards to your profile, or copy a share link that opens the exact setup for anyone

Assumptions

Cards default to standard conditions (59°F, sea level, 50% relative humidity) unless you change them. Elevation is the scope come-up from your zero; wind is a full-value crosswind estimate. See the methodology for the model and its limits, and the accuracy page for how it validates.
