Reloading Calculator

Reloading Calculator turns your own load-manual numbers into a charge ladder, a per-round cost, and a saved list of loads you come back to.

Use this handloading calculator to lay out a charge ladder, compute case fill, and price a round from your own component costs. This app carries no published load data of its own - every charge weight you see is a number you typed in from your own manual - and the underlying formulas are shown on screen so you can check the math.

CHARGE
- Enter a start charge and a max charge (from your own load manual) and a step count to build an evenly spaced charge ladder
- Pick a cartridge from a nominal case-capacity list or enter your own measured case capacity
- Set a powder bulk density, or use the built-in default
- See each ladder step's charge weight in grains and grams, percent of max, and case fill percentage
- Compressed, low, and high fill percentages are flagged so you can re-check figures that may not belong together
- Save a ladder to the Loads tab; the first saved load needs no ad

COST
- Enter brass cost per case and how many times you expect to reload it
- Enter primer cost, powder cost per pound, charge weight, and bullet cost
- See cost per round and cost per box, broken down by component
- Choose a 20-round or 50-round box, or enter a custom count
- Compare against a factory ammunition box price to see the per-box and percentage difference
- Save a calculation to a running history list

LOADS
- Save charge ladders built on the Charge tab, or add one by typing figures in directly
- Reopen a saved load to reload its figures onto the Charge tab
- Delete any saved load
- The first saved load needs no ad; saving more unlocks with a short rewarded ad

SAFETY
This app holds no load data and never proposes a charge. Every charge weight on the Charge tab comes from your own load-manual entry, not from the app. The published manual from your powder or bullet manufacturer is the authority on what to load - this app only does the arithmetic on the numbers you already have.

BUILT FOR THE RELOADING BENCH

This app is ad-supported. The charge ladder and cost calculations are always available; saving a second load or watching your cost history unlocks with a short rewarded ad.
