Factory-Load Drop Charts
Every chart starts from the ammunition maker's own published muzzle velocity and the bullet maker's published BC, and runs the same verified solver as the calculators. The output is a prediction — your barrel, your lot, and your air will move it. The truing guide shows how to correct a chart to your rifle in two shots.

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.
