3x5" Hard Data Card
This compact 3x5" data card is designed to fit in your armband or card pouch, making it a convenient tool for tracking your platform's ballistic data in real-world conditions. The template covers distances from 100 yards (or meters) out to 1,000 yards in 20-yard increments, giving you quick, reliable access to precise shooting information.
The card incorporates the short wind formula applied to 100-yard intervals, helping you estimate wind adjustments with your specific settings.
Perfect for Recording:
Date
Platform and load details
Environmental conditions
Holdovers and adjustments
Having your critical data on hand means less reliance on a ballistic solver and faster target acquisition.

Key Takeaway
A hard data card provides crucial ballistic information for precision shooting, allowing shooters to have quick and reliable access to data without needing an electronic device.
Summary
Hard data cards are essential for precision rifle shooting, offering quick access to ballistic data.
These cards include information about the rifle, load, and environmental conditions.
They are vital because relying on electronic devices can lead to issues if the device fails or is unavailable.
Creating a hard data card involves setting up a ballistic profile in an app-based solver, chronographing your rifle, and recording environmental conditions.
Proof the platform at significant distances (e.g., 600 yards) to confirm the accuracy of your ballistic profile.
Use a template to create your card, which can be downloaded or purchased.
The card should cover rifle details, environmental factors, ammunition used, and additional notes such as date and location of zero range.
Information should be recorded in frequent increments, usually every 20 yards up to 1,000 yards, for precision.
A different data card should be used for varying environmental conditions or geographical locations.
The "gun number" is a tool to understand wind effects and is calculated based on full-value wind speed.
Gun number helps with estimating how wind will impact the bullet flight path.
Utilize an armband to have the hard data card and its information readily accessible during shooting sessions.
The cards sold offer a stage diagram and wind columns for additional strategic planning, including real-time conditions.
The gun number concept allows quick mental calculations for wind, which is crucial during shooting stages.
