Has anyone had success modifying the sun screens on their chronograph? I was shooting some new loads this weekend and was getting some erratic readings. The sun was in the 10 o'clock position. I had the factory screens in place.
I fired 5 rounds of 230g 45acp. The indicated speeds were 97, 99, 87,101 and 100. I shot some factory rounds with the same results.
Either my chronograph is failing or possible lighting issues? Can temperature effect the readings? This was the first time I shot with it in cold weather.
It was set for FPS, not MPS. I also tried a fresh battery.
