I have never Chronoed a handload this time of year. Just getting over the major part of hunting season and more hunting to come so I never took the time. However, I did try out some loads in a .356 Win. since I had time this week. The velocity went from 2200 fps down to 366 fps. This happened with all loads and never happened before with this Chrono, a Past. The sun is way south of us right now and hitting the screens at a pretty severe angle. Does this affect how the Chrono reads and thus mess up the reading? New battery in the Chrono.
