Free Reloading Calculators

Eight free tools for handloaders and shooters. No signup, no tracking, math runs in your browser. Each tool opens with a plain-English glossary so the vocabulary does not get in the way. Use them at the bench; save the real data in BrassTracker.

At The Bench

• Charge Ladder

  Plan a powder workup. Enter start charge, max charge, and step count; the tool builds the ladder and totals the powder you will need.

• Group Size

  Measure the cluster of holes on a target. Type the extreme spread or paste shot coordinates; get every group statistic worth knowing.

• Scope Adjustment

  Zero your scope, move point of impact deliberately, or convert MOA, mil, and inches at any distance. Visualize tab shows the dot moving on a target as you click.

After The Range

• Cost Per Round

  What it actually costs to build one round at home. Spreads brass cost across its real life the way an honest accountant would.

• Truing Solver

  Your ballistics app's predicted drop did not match what you saw at the range. The tool returns the muzzle velocity that makes the math line up with reality.

• Velocity Stats

  Paste the chronograph readings. Get average, ES, SD, CV, and min/max. Same math the BrassTracker app uses for chrono sessions.

Reference

• Cartridge Specs

  Look up SAAMI / CIP case length, trim length, max OAL, and primer size for 80+ common rifle, pistol, and shotshell cartridges.

• Range Day Card

  Live preview of the share card BrassTracker exports after a range day. Firearm, load, group, chrono, and conditions on one image. See what gets posted before you install.
