Mr. B: You are right: the Leupold I mentioned isn't "that old" relatively speaking. However, as I read most of the optics threads, it appears to me that the biggest share of the posters would think so and never seriously consider using one like it on one of their hunting rifles. I suppose it's my age and conservative mine-set that drives me to buy something of good quality believing it will last a LONG time, it will serve me well, and that I won't have to replace it within a few years. I realize the quality of today's optics surpassed this old Leupold (there I go again with that old thing) years ago, but that doesn't bother me at all. Gosh, I even used another similar vintage Leupold successfully last fall in Alaska. What was I thinking !!
