This video from Precision Rifle Network, featuring Justin H., details the practical application of the Garmin Xero Chronograph within Precision Rifle Series (PRS) competitions. It covers mounting options like ARCA and Picatinny, and explains how to leverage velocity data during and after stages to verify ballistic calculations, troubleshoot accuracy issues, and confirm consistency between ammunition lots, particularly for rimfire shooters and ELR applications.

Quick Summary

The Garmin Xero Chronograph is a valuable tool in PRS competitions for verifying bullet velocity against ballistic calculators. It can be mounted via ARCA or Picatinny rails and helps troubleshoot accuracy issues, confirm ammo lot consistency, and track performance during barrel break-in or temperature changes, ultimately eliminating velocity as a variable.

Frequently Asked Questions

What are the primary mounting options for the Garmin Xero Chronograph in PRS competitions?

The Garmin Xero Chronograph can be mounted using an ARCA rail mount, which is common on modern rifles, or a Picatinny mount, often found on scope rings. The ARCA mount offers broad compatibility, while the Picatinny mount is more low-profile.

How can a chronograph help during a PRS match?

A chronograph helps verify that your actual bullet velocity matches your ballistic calculator, allowing you to troubleshoot accuracy issues, confirm ammo consistency between lots, and track performance during barrel break-in or temperature changes.

When is it not ideal to use a chronograph during a PRS stage?

It's generally not recommended to use a chronograph on stages that require shooting through tight spaces, windows, or involve significant maneuvering, as the added bulk can slow you down and potentially get snagged.

What is the main benefit of using a chronograph for problem-solving in shooting?

The main benefit is eliminating velocity as a variable when diagnosing accuracy problems. By confirming your velocity, you can rule it out as a cause for shots going high or low, allowing you to focus on other factors like wind or shooter error.
