Made for the shooter who wants the numbers to make sense
You understand basic rifle operation. You may know what a zero is, or have seen G1, G7, BC, MOA and MRAD on a box or ballistic app and quietly wondered which bits actually matter.
Ballistics 101 starts with the rifle and follows the projectile through the muzzle, flight, gravity, drag, wind and target. It uses plain language first, then adds the technical detail without pretending the hard parts do not exist.
Inside the guide
Why does it cost $7.99?
Because Within Range has running costs. The core tools are intended to remain freely available. Buying the guide helps contribute towards hosting, development, research and keeping the project running.
The reader gets something genuinely useful and the project gets a little more runway.
A useful guide, not a promise
The guide explains what ballistic calculators can predict and what they cannot. It keeps mechanical capability, ballistic prediction, shooter capability, environmental uncertainty, terminal performance and ethical shot selection separate.
Ballistics 101 is educational material. It is not a loading manual, legal advice, firearms-safety training or a statement that any particular range is an ethical hunting distance.
