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
- Fast entry with minimal taps
- Works offline at the bench
- No account required
- Your saved loads and cost history stay on your device

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. ## Rankings - #2,944,665 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.WAKE_LOCK` - `com.android.vending.CHECK_LICENSE` - `com.google.android.gms.permission.AD_ID` - `com.k4y.reloadingcalculator.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Reloading Assistant](https://chrome-stats.com/d/com.polycompsol.reloadingassistant) — 162,738 users, 4.31 / 5 - [Handload: Reloading Log & Data](https://chrome-stats.com/d/com.standy.handload) — 47 users - [Load Book](https://chrome-stats.com/d/com.project983.loadbook) - [GUNR - Cost of Reloading](https://chrome-stats.com/d/com.spaza.cor) — 1,851 users, 2.20 / 5 - [LoadBench Reloading](https://chrome-stats.com/d/com.loadbench) — 238 users - [Askari Reloading Tool](https://chrome-stats.com/d/com.yourname.reloadingappbasic) — 48 users - [RANGE & RELOAD LOG](https://chrome-stats.com/d/com.nimscraze.range_reload_log) — 10 users - [Strelok QuickLoad](https://chrome-stats.com/d/com.strelok.reload) — 202 users - [Scott's Guide - Reloading Ref](https://chrome-stats.com/d/com.scottsguide.app) — 3 users - [RAD Development](https://chrome-stats.com/d/com.reloadingallday.RADD) — 918 users, 4.82 / 5 - [ApexLOAD FIELD](https://chrome-stats.com/d/com.apexload.field) — 69 users - [CarryCalc](https://chrome-stats.com/d/com.bharat.rto.vehicle.information) --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.k4y.reloadingcalculator)
