I also have a 10x S/S. Got it in a trade and have hung on to it. It's been on a 1/2 dozen different rifles, and it takes a lickin' and keeps on tickin'. It's the cheaper one with the rear parallax adj. The knobs are stiff, but it tracks. I've sold rifles out from under it, but kept it. It's funny, I like the big Leupolds better, but I hang on to this one.

A big fast bullet will beat a little fast bullet every time
