Shooting apps, shot timers & ballistic tools

A shot timer and a ballistic calculator are the two tools that change how most people practice. The timer makes progress measurable; the calculator turns guesswork at distance into a starting point you can confirm with real impacts.

For ballistic apps, the output is only as good as the inputs: measure your actual muzzle velocity, use the bullet's published ballistic coefficient, and enter your real sight height and zero distance. Then confirm the solution on paper or steel before you trust it.

Laws change and vary by place. Reference sites are a good starting point, but always confirm current rules with official sources.
