Your Garmin Xero Has the Data — Here's What to Do With It

The Garmin Xero is a fantastic chronograph — it catches every shot's velocity without a tripod or a sky screen to align. But the velocity is only step one. Here's how to actually use that data.

Getting the data off the Xero

Every session lives in the Garmin ShotView app on your phone. Open a session, and you can share it out as a CSV file — a plain spreadsheet of your per-shot velocities plus the session's average, SD, and extreme spread. That CSV is the raw material for load development.

What the numbers mean

• Per-shot velocity — the speed of each round, in order. Across a powder ladder, this is how you spot your velocity flat-spot.
• Average — the string's mean speed; what you feed a ballistic solver for your DOPE.
• SD — consistency. Single-digit SD is the target for a load you'll trust at distance.
• Extreme spread — fastest minus slowest in the string.

The gap most shooters hit

The Xero hands you clean velocity data — but it doesn't tell you which charge to pick, it doesn't connect your speeds to your groups on paper, and it doesn't predict your drop. That's the work that usually ends up in a hand-built spreadsheet, and it's where most load development stalls.

The point of a chronograph is the decision it enables: which load is best, and where will it hit at distance. Velocity is the input; the scored load and the DOPE table are the answer.

From CSV to a decision

Loadscope reads your ShotView CSV directly — no retyping velocities — alongside your target-group data, scores every charge and seating depth, names the winner, and predicts your full DOPE from the velocity the Xero actually measured. The data you already have, turned into the call you're trying to make.
