The card you tape to the stock: come-ups from your zero, in your turret's units, with a full-value 10 mph wind column beside them. Built from the same gated solver as the trajectory calculator.
Read this before you rely on any number here. Predictions use the standard G1/G7 drag models and the data you enter — they are estimates, not measurements, and they are never load advice. Confirm with live fire at distance. For anything you load yourself, work only from current published manuals (Hodgdon, Sierra, Hornady, Lyman), start low, and work up. TruingLog publishes no load recipes and suggests no charge weights.
