Laminated 4”×6” quick-reference cards that covers the field ballistics variables that shift impacts at distance, so you can make cleaner corrections under pressure without digging through notes.
What’s on the card:
Windage: step-by-step wind process, wind clock values, relative wind concept
Inclination: cosine correction
Density Altitude (DA): what DA is, how it affects drop and drift, and when to confirm DA in the field
Spin Drift: what it is, twist direction effects, practical application, and when it becomes noticeable
Coriolis: what it is, direction by hemisphere, practical relevance, and when to account for it
Velocity & Vertical Dispersion: SD/ES definitions and SD performance guidelines
Specs:
4” × 6” (100 × 150 mm)
Fully laminated, water-resistant, range-safe
Clean high-contrast layout for quick reference
Ideal for:
Precision rifle shooters, long-range hunters, PRS/NRL competitors, new shooters, instructors/coaches.
Designed and produced in-house. Custom cards and bundle options available.
Range role
Use the Ballistics Field Card Set as a field prompt for wind, inclination, density altitude, spin drift, Coriolis and velocity spread when small variables start moving impacts at distance.
Best fit
Best for precision rifle shooters who want a compact ballistics reminder beside their DOPE and solver data. It is useful for match prep, coaching moments and field sessions where you want the why close to the correction.
