Thread: Never lend your chrony to a mate

The rare few that got to shoot over my optical chrony shot under the proviso that "if they hit it they owned it". And then I also checked their set up each time.
With the MagnetoSpeed I will let a few mates use it but I set it up on the rifle.
One of my earlier chronographs had a bullet scorch mark across the top of the sensor from a "competent" shooting mate. I didn't see it until I got home - I treated that as lesson 1, never ever lend chronographs (or chainsaws). At least with yours the error was upwards not downwards ha ha.
