[QUOTE="HSmithTX, post: 2597279, member: 121677"] If you are using a sky screen type of chrono you need to know a bit of chrono-fu to get consistent readings in differing light conditions. When I was using one a lot I primarily used a IPSC no-shoot (white cardboard) on top of the screens in most light conditions. If it was really bright out I would flip the target and let the screens look up at the plain brown cardboard. The only one I used that didn't need regular manipulation was an Oehler 35P, it was quite forgiving but many times more money than the typical chrono people use. Regardless I would test with a known load before chrono'ing anything for score, sometimes brown and sometimes white worked best but I think I could count the number of times I saw them work well with no cover without taking my shoes off or my zipper down and have a couple fingers to spare....
