In-depth looks at precision shooting, explained simply and backed by verified numbers.

Near zero, far zero, and what a 10-meter error in the zero range really costs.

Same reasoning as the .308, very different numbers: zero, range and wind with the rimfire.

The three inclined-shooting rules put to the test: where they agree and where they part ways.

The Speed Drop Factor: elevation you dial from memory, and how accurate it is.

The Quick Wind Factor: a wind correction you make from memory, and how accurate it is.

Density altitude: the air that slows the bullet, explained simply.
Technical terms are explained in the glossary.
