How Shooting Works — 12 Interactive Ballistics Demos

A free interactive visual explainer of the core ballistic and optical ideas behind every shot. Move the sliders, watch what happens. Universal physics, applicable to bullets, arrows, and shotgun patterns.

Twelve interactive widgets cover trajectory and line of sight, angular vs linear precision, how groups are measured, precision vs accuracy, wind drift, hold vs dial, click value, parallax, first vs second focal plane, MIL ranging, atmospherics (wind, temperature, density altitude), and ballistic coefficient. Each widget uses sliders the user can move directly to see how a single variable changes the outcome.

The page is structured so a beginner can read it end-to-end as a primer or an experienced shooter can jump to a specific concept. No numeric readouts in the discipline-neutral primers; quantitative widgets show real units (MOA, MIL, click values).

Using the interactive illustrations

Move a slider to see how one variable changes the diagram. Examples cover true MOA, angular spread at different distances, parallax, and reticle subtension. The diagrams illustrate relationships; distances, drops, group sizes, and unit scales may be exaggerated. Do not use their numbers as firing solutions.

For the mental side of shooting, see /focus: a box breathing pacer, a quiet-eye fixation trainer, a pre-shot routine builder with a printable card, and a Stroop attention game used as a pre-load state check.
