Frequently Asked Questions

What is the purpose of the 'ultimate data card' presented by Jimmy B Rodriguez?

The 'ultimate data card' is designed to provide essential ballistic information for shooters to operate fully analog, meaning without relying on electronic devices like Kestrels or rangefinders, which is useful in situations where electronic use is not feasible or desired.

How can the data card be used for angled shooting?

For angled shots, the data card includes a section where you find your shooting angle in degrees. You then multiply your final ballistic solution by the cosine of that angle to make the necessary elevation adjustment.

What information can be tracked in the 'Ammo Shift' section of the data card?

The 'Ammo Shift' section is for noting zero shifts related to different ammunition types (e.g., green tip vs. Mark 262) or for tracking zero adjustments needed when switching between suppressed and unsuppressed firearm configurations.

How does the data card facilitate quick ranging without a laser rangefinder?

The card allows for quick ranging by using the rifle's reticle to measure a target's size in mils. This measurement is then correlated to a known distance using a chart, typically based on a standard 12-inch target size for humanoids.

What are the key elements for wind calls and adjustments on the data card?

The data card includes columns for quick wind calls and spin drift adjustments, which become important at longer ranges. It also features a section for moving target holds, allowing adjustments based on the target's speed relative to a reference wind speed.
