This video demonstrates the setup and use of the Caldwell Ballistic Precision Chronograph. It provides practical insights into measuring ammunition velocity, comparing factory loads to reloads, and understanding the impact of suppressors on perceived sound. The presenter, Steve from Mr. Big Kid, highlights the ease of use for obtaining accurate load data.

Quick Summary

The Caldwell Ballistic Precision Chronograph is easy to set up with a 9-volt battery and sensor paddles. It measures ammunition velocity in FPS or MPS, aiding in accurate load data for handloaders. Testing showed Winchester White Box 115-grain FMJ averaging around 1200-1250 FPS, while reloads were closer to subsonic speeds.

Frequently Asked Questions

How do you set up the Caldwell Ballistic Precision Chronograph?

The Caldwell Chronograph requires a 9-volt battery. Its two sensor paddles clip onto the sides. A cord is provided for phone connectivity, though compatibility may vary with newer iPhones lacking auxiliary ports. Once powered on, it initiates a countdown before being ready to measure shots.

What are the typical velocity readings for Winchester White Box 115-grain FMJ ammo?

When fired from a CZ P10 C with a Rugged Obsidian 45 suppressor, Winchester White Box 115-grain FMJ ammunition averaged velocities between approximately 1200 and 1250 feet per second, showing consistent performance.

Can a Caldwell Chronograph help with handloading ammunition?

Yes, a Caldwell Chronograph is invaluable for handloaders. It allows you to accurately measure the velocity of your reloads, helping you fine-tune powder charges to achieve desired performance, such as consistent subsonic speeds or optimal accuracy.

What is the difference in sound between factory and subsonic reloaded ammunition?

The video demonstrates that even reloaded ammunition that is just over 1000 FPS is significantly quieter than factory loads like Winchester White Box. True subsonic rounds (under 1000 FPS) are even quieter, especially when fired through a suppressor.
