[QUOTE="longestrange, post: 2080603, member: 75265"] Optical chrony's will error out if too close to the muzzle - no reading. Rifle rounds require more distance than pistol rounds. Whether this is due to the muzzle blast or shockwave shadows or whatever I don't know. It is possible that this effect is taking place more subtly at marginal distances, causing the crony to trigger prematurely/erratically depending on individual trajectories over the sensors. You may want to move it another 10 or 15 feet out to see if that helps. This might also explain somewhat the sunny/cloudy differences, as a shockwave shadow would have more effect on a sunny day. The screens do seem to help with this while they survive ;) I can't test this theory at the moment but it would be interesting if anybody else could have a look. Like my old prof used to say - 'One good test is worth a thousand expert opinions'. [/QUOTE]
