Mine can be erratic with 223. Works fine for larger calibers for me.
Probably just my inability to set it up properly. If anyone has any tips for running one of these reliably with a 223 I would appreciate it. Bumping my sensitivity doesnt appear to help that much.
Also on occasion, mine will give an obviously exaggerated velocity. One shot out of a five shot string of book max loads will read 1000 fps faster, for example. With otherwise single digit SDs and hot loads, I doubt I'm screwing up that badly or I would have blown myself up by now.
