I was at the range and a guy and his buddy were trying to adjust the windage on a lever-action Marlin. I was down at the other end and didn;t see what caliber they were shooting, but one guy would hold it and the other guy would tap with a hammer and a little stick of wood or something. Then they'd try a few shots and start tapping from the other side. After a few shots, back they were tapping on the original side. They weren;t marking (with tape or something) to be able to tell whether or how far they moved the sight in the slot, so they were guessing the whole time.
I thought about taking my masking tape down to them and making a suggestion, but by that time they had already ticked me off with stopping the range every 2 or 3 shots so they could go down and see their target. Most guys will wait and watch the other shooters and try to guage when a good time is to go downrange, but not these two. So I let them mess with it. I don;t know if they ever got it right enough.
But back to scopes and sights: I put the Weaver K4 (fixed 4x scope) back on the rifle with Burris low rings. It doesn;t really need it, but I like shooting with the scope. Before I re-mounted the scope, I made sure the sights were dead-on, so it's ready to go if I someday rip that scope off again.
