Loadscope does the rest.Scored, ranked, and charted — your best load called out.
$59 launch price — one-time, yours forever with free updates. Goes to $79 at full release. Mac or Windows.
Enter your ladder — powder or seating depth, start, step, how many. Loadscope lays out every load so you just shoot it in order, then matches each result to its charge. No naming files, no typing velocities, no spreadsheet wrangling.
Plug the Garmin Xero into your computer with its USB cable and Loadscope sees it — it tells you how many sessions are on it and asks which ones belong to this ladder, listed by time, shot count, speed and SD. No ShotView, no exporting one session at a time. Shooting something else? Drop a file or a whole folder and hit Run — the format is auto-detected, so there's nothing to format or label. Already shoot through a target app? Its export imports the same way.
No separate target app needed. Photograph your target, set the scale, and tap your shots — Loadscope works out group size, mean radius and vertical, then scores it. Shoot a whole powder or seating-depth ladder on one sheet and measure every charge in a single pass. Prefer your phone? Measure at the target and pull the groups in over Wi-Fi. Already use a target app? Import its CSV instead.
Sample target shown for demonstration only.
Every load scored into one winner — and charted so the flat-spot pops. Tune the weights and Loadscope re-scores from your existing data, no re-import.
Sample data shown for demonstration only — not load data. Always work up from your published manual.
Every charge you tested, scored and ranked — your winner tagged at the top. Seating depth gets the same treatment in its own log.
Elevation, wind, drop, velocity and energy — 100 to 1000 yards, on a card that fits your pocket.
Every winning load gets a one-page Load Card — components, CBTO, and the numbers it actually produced. Print it or Save as PDF.
Loadscope Ballistics carries your best load to the range, re-solves your dial live as conditions change — real wind math, powered by Apple Weather — and measures your groups right at the target, syncing them back over your own Wi-Fi. No cloud, no account; works with no signal.
Free to download — desktop owners unlock everything; anyone else unlocks phone-side load entry for a one-time $9.99.
Real reloaders, real range days.
“Hand input works perfectly. Your system found this [load] also. I will be telling everyone about your software.”
“This is an awesome app with outstanding service behind it.”
“Great app for load dev. One of the easier apps out there — even keeps load recipes and barrel rounds.”
Tested on macOS Sonoma & Sequoia and Windows 10 & 11.

A one-time $59 purchase — the full app, yours forever, with free updates. No subscription, no account, no cloud — and it works fully offline.
Shooters running powder ladders and seating-depth tests over a chronograph — groups measured right in Loadscope, or imported from a target app if you use one. If you're developing a load right now, you're who we built this for.
Reads Garmin Xero, LabRadar and more; measures your target groups from a photo, or imports BallisticX, OnTarget, Silver Mountain or ShotMarker. Shooting a device we don't list yet? Send a sample CSV and we'll add it.
The full desktop app on Mac and Windows, free updates, and up to two computers per license. 30-day money-back guarantee. The iPhone & iPad companion is a free download.
Every winning load stays in the app — active and archived, in one searchable list. Pull any of them back up, or print the whole library or a single Load Card. Building on one? Rework it — a fresh ladder opens with that load’s rifle and components filled in, your original untouched.
Shot the same bullet over three powders? Select the saved loads from one rifle and Loadscope lines them up head-to-head — scoring velocity SD, group, and vertical — then calls which one shot best.
Loadscope tracks total rounds through each barrel. Set a starting count once; every imported session adds to it automatically, and a + Add button logs the practice or match rounds you didn't import.

No single number tells you a load is good — a tight group that wanders in velocity will betray you at distance, and a flat velocity string over a wide group won't hold either. So Loadscope doesn't pick your best powder charge or seating depth on one stat. It scores every charge and every seating depth you tested across four things that actually show up on target.
Those four: mean radius (true group center, not one flier — falls back to group size when only that's available), velocity SD (shot-to-shot consistency), vertical (vertical dispersion — what costs you elevation at distance), and a light flat-spot signal (how little your average velocity moves across nearby charges).
Each metric is put on the same 0-to-1 scale (lower is better) so they're comparable, then blended into one composite score. Lowest composite wins — Loadscope tags it 🥇 and writes the winning charge or CBTO to the top of the tab. Every candidate also earns a "Best in:" tag for any single metric it topped, even if it didn't win overall.
The four aren't weighted equally, and the mix isn't a fixed table — Loadscope sets it from the distance you tested at. Up close, mean radius leads and velocity barely counts; at 1000 yards velocity SD takes over, because that's where a few fps of spread opens real vertical. Seating-depth tests lean on mean radius, since seating tunes group shape, not speed. Every weight is still yours — the app's Scoring tab is a set of sliders, and Use recommended weights hands the dial back to Loadscope. Read the full method →
Click Get Loadscope, check out for $59, and your license key is emailed to you right away — it unlocks both the download and the app itself. One purchase covers up to two computers. Questions? support@loadscope.app.
No. Loadscope is a one-time purchase — $59 at launch (going to $79 at full release). Pay once and it's yours, with free updates, not a yearly subscription. It runs fully offline with no account and no cloud. The iPhone & iPad companion is a free download.
Up to two — for example your bench PC and your range laptop. Both keep working offline once activated. If you move to a new computer and need to free a slot, email support@loadscope.app and we'll reset it.
Loadscope uses a G7/G1 point-mass ballistic solver — the same model class as Strelok, GeoBallistics and the free Hornady/Berger calculators — checked against two independent references, JBM Ballistics and Applied Ballistics' own published range card. Measured-drag solvers like Applied Ballistics and Hornady 4DOF pull ahead deep in the transonic. Predicted values are an estimate, not a measurement — always confirm by live fire at known distances before relying on them for a shot that matters.
Grey italic numbers are predicted by the solver from your bullet, muzzle velocity and conditions. At the range you type what you actually dialed — that row turns solid white = confirmed. Click Save DOPE and Loadscope writes both to your workbook: predicted rows stay grey italic, confirmed rows print solid. Predictions never overwrite confirmed data (only the reverse), and your printed Pocket Card carries a "verify at the range" banner until every row is confirmed.
The most popular match bullets have their BCs built in. For any other bullet, type its BC off the box or the maker's site once. It's not a source of published load data — you still cross-reference charges against current reloading manuals. The bullet database grows over time with no app update needed.
Chronographs: Garmin Xero — either plug it into your computer with its USB cable and Loadscope reads the sessions straight off it, or import a ShotView CSV export; both work, and neither one replaces the other — plus LabRadar, MagnetoSpeed and Athlon Velocity Pro. Target apps: BallisticX, OnTarget (PC/TDS), Silver Mountain (SMT) and ShotMarker — or skip the target app entirely and measure your groups from a photo right in Loadscope. The parser system is pluggable, so a new chronograph or target app is quick to add — send a sample export to support@loadscope.app and we'll fold it in.
No. Plug the Xero into your Mac or PC with its USB cable and Loadscope notices it, tells you how many sessions are on it, and offers to read them — every session at once, straight off the chronograph. Since a Xero holds up to 50 sessions, it asks which ones belong to this ladder and lists them by time, shot count, average speed and SD, grouped by range day, with the likely block already picked for you. It never writes to or erases anything on the chronograph. The Xero stores its sessions as Garmin .FIT files, and Loadscope reads those directly — drag one in on its own if you've already copied them off.
And you don't need the cable every time. The ShotView route works exactly as it always has: export a session as a CSV from the app on your phone and drop it on Loadscope. Both paths land in the same place and score the same way — use whichever you have with you that day. Working with Garmin Xero data →
No. Loadscope has built-in group measurement — photograph your target, set the scale off a known reference, tap your shots, and it works out group size, mean radius and vertical for you, then scores it. Shoot a whole powder ladder — or a seating-depth ladder — on one target sheet and measure every bull in one pass; you tell it which bull is which. Or measure on the iPhone in the field and pull the target groups into the load over Wi-Fi. Already run a target app? Import its CSV instead — your call. How measuring from a photo works →
No. Loadscope writes to a regular .xlsx file on your computer. No account, no sync, no telemetry. Your loads stay on your machine.
No. Loadscope does the work itself — your scored results, best load, predicted DOPE, and printable Load & Pocket Cards all appear right inside the app, no Excel required. Excel only matters if you want to open the underlying workbook and poke around the formulas yourself. Even then, the file is a standard .xlsx that opens just as well in Numbers (free on every Mac), Google Sheets, or LibreOffice. Excel is recommended for the full spreadsheet experience, but it's not required to use Loadscope.
Mac: yes. Signed with a Developer ID Application certificate and notarized by Apple. macOS opens it without security warnings on the first launch — the same as any commercial app.
Windows: yes. Signed by Loadscope LLC with a Certum code-signing certificate and timestamped. Because the certificate is new, Windows SmartScreen may still show a one-time More info → Run anyway prompt until it builds reputation — the publisher reads “Loadscope LLC”.
Mac: macOS 10.13 or newer. Runs natively on both Intel and Apple Silicon (M-series) Macs — no Rosetta needed.
Windows: Windows 10 or 11, 64-bit. No GPU required. Loadscope is a small app — runs fine on modest hardware.
Loadscope Ballistics is available on the App Store for iPhone and iPad — a field companion, not a phone port of load development. It carries your confirmed load to the range: a DOPE dial that re-solves live as conditions change, real crosswind math, your recipe at the bench, and round counts that sync back to the desktop. It's free to download — desktop owners unlock everything, and anyone else can unlock phone-side load entry for a one-time $9.99. The desktop stays Mac & Windows for the actual load-dev work.
