So I have waited ages to get my mits on a chronograph and finally got hold of a CED mil! I packed my kit and headed down to my shooting ground on a local farm. I have been wanting to test some of my loads out to make my drop charts accurate etc. First round and Qed ready and lined up , nothing , no reading. All rounds fired the same! Weather:- sunny at about 5pm. Try connections still nothing. Back home next day I tried my air rifle through it in the garden .I find if I shoot low I can get a reading regularly prob 80% of the time if kept low. Weather :- sunny 2pm Today back to the field with .22 rimfire (for test shots)and .243 . Weather :- cloudy 5Pm Set up, nothing until about a dozen .22 later when I am trying to keep low and I shoot the front screen just in the top of the sensor! Guess what I get a reading, just the one though! The lens is blown out and the casing shattered. Is it just me and the weather or do you think I should be able to get readings easier like half way up the screen?
