It works. I chrono'd several rifles with one today. Only 1 rifle gave a surprise reading, My 257Wby was ~150fps faster than I anticipated (3810fps vs. 3665fps), going to check it again during a different range session. Everything else was within 30-50fps of what my old green Chrony read under good light conditions. I had 1 non-read each from my 223AI and 22-250, both were 75gn A-max's that's out of 25 shots between the 2 rifles. A friend showed up and it read 9 of 10 shots from his .20 Practical. Bullet diameters of .243, .257, .277, .284, .308, and .375 all read without missing a beat. 6 brand new AA batteries showed 50% life left after a 3hr range session. It's stupid simple to set up and use as well.
