Does anyone use the Lyman SML 57 sight on thier rifles? I am having a lot of trouble with this sight and can't solve my problems. Seems the clip holding the elevation screw keeps falling out. I've discovered that my local NAPA store stocks E Clips that are close enough to size that I can file and stone them enough to fit but the really aren't right and are a pain to keep the proper tensioning on the elevation screw to work properly.. I have bought more of the correct clips from Lyman to no avail. Because if you have to adjust your sights often, as I do,  pretty soon I discover the clip is gone and my scores plummet. I shoot competition 25,50,and 100 yards and change sight settings to compensate for distances. I don't adjust my powder charge. I'd love to find another decent sight.

Thanks,
