[QUOTE="AJ Peacock, post: 286119, member: 4885"] This is tough. I had 2 chrony's and I thought one of them was reading too high. So I spent a lot of time trying to figure out how to verify correctness. I thought about dropping something from the top of a building through the chronograph. I could calculate the speed and see if the chrono read correctly. I decided the speed would be too slow to verify within 1% or so. After shooting all my rifles through the new chronograph and getting readings that are completely 100% within my expectations, I started trusting my new chrono. I also shot some 22LR through the chrono and they matched what I was expecting (looked for velocity figures for the ammo on the internet). I also verified that my drops fit my Exbal estimates when using the velocities from my new chrono. If you figure out a good way to verify your chrono, please share your idea. AJ [/QUOTE]
