Quick Answer
In the United Kingdom, there is no specific statutory legal requirement dictating how long individual shooters must keep their personal range cards. Instead, the retention of range cards falls under best practice for personal development, safety, and performance analysis. We recommend keeping your range cards for as long as they remain relevant and useful to your shooting progress, typically until the data is superseded by more accurate information, or for a period of one to two years to allow for effective pattern recognition and improvement.
The Purpose of Range Cards
Range cards, often referred to as data on previous engagements (DOPE) cards, are invaluable tools for responsible shooters. They serve as a condensed record of ballistic solutions for a specific firearm and ammunition combination at varying distances, under different environmental conditions. These cards typically include data such as elevation and windage adjustments (clicks or holdovers), muzzle velocity, ballistic coefficient, temperature, humidity, and barometric pressure for various ranges.
They are crucial for achieving precision, especially in long-range shooting where even slight environmental variations can significantly impact bullet trajectory. By systematically recording your successful engagements and the conditions under which they occurred, you build a reliable personal ballistic library. This data allows you to make informed adjustments rapidly and accurately on the range or in the field, leading to improved consistency and safety.
Practical Retention for Performance and Safety
Since range cards are primarily performance-oriented tools, their retention duration should be guided by their utility. Consider these practical points:
- Until Superseded: The most direct approach is to keep a range card until you develop a new, more accurate, or updated version. This might happen if you change ammunition batches, components for hand-loads, rifle setup, or if you gather more precise data through extensive testing. Always use the most current and validated information.
- For Analysis and Improvement: Retaining older range cards, even if superseded, can be beneficial for historical analysis. Looking back at previous data can help identify trends, diagnose performance issues, or track your skill progression over time. A retention period of one to two years allows for a comprehensive review of seasonal variations or changes in your shooting technique.
- Supporting Your Range Visits: Range cards are a key component of a comprehensive record of your shooting activities. We strongly advise recording key details after each range visit to track your progress and comply with best practice for certificate holders. For guidance on what to log, see our article on What Should You Record After Each Range Visit in the UK?.
Differentiating from Legally Mandated Records
It's important to distinguish between personal performance records like range cards and legally required documentation for UK firearms certificate (FAC) holders. While range cards are a best practice for improving your shooting, their retention is not explicitly mandated by law. In contrast, other records carry specific legal or compliance requirements:
- Ammunition Records: While individual shooters are not legally required to keep ammunition purchase receipts, it is crucial that firearms dealers maintain detailed records of all ammunition sales. Keeping your own log is still highly recommended for personal inventory management and accountability. Learn more in our guide: Do You Need to Keep Ammunition Purchase Records in the UK? Law, Receipts, and Best Practice.
- Club Attendance Records: Approved rifle clubs in the UK have clear statutory obligations regarding the retention of attendance records for members and visitors. These records are vital for demonstrating legitimate use of firearms and for certificate renewal processes.

Enhancing Your Shooting with Range Card Data
Effective use and retention of range cards directly contribute to safer and more proficient shooting. They help you understand how factors like wind influence your shots, a critical skill particularly for long-range disciplines.

For specific shooting activities, such as deer stalking, maintaining comprehensive records beyond just range cards is essential for responsible practice, traceability, and demonstrating compliance with wildlife legislation.

Practical Bottom Line.
While no legal timeframe exists for keeping range cards in the UK, prudent shooters should retain them as long as they provide actionable insights for improving accuracy, consistency, and safety. Treat them as dynamic working documents that evolve with your shooting journey. Regularly review, update, and replace them with the most current data, but consider archiving older versions for retrospective analysis to maximise your development.
