Smokinjoe: If I had a .300 Wby, I'd use a Leupold, too. I never shot one, but I have shot a.338 Win off the bags, and I've heard the .300 Wby kicks even harder than that.
Got to the range last weekend. The NC Star 2X pistol scope held its' zero just fine. Adjustments were smooth and predictable. This on a Ruger MK II .22LR, though. I don't have any harder-kicking handguns that will take a scope, but I have high hopes that the NC Star will hold up on the pipsqueak so I can get my $40 worth of use from it. The eye relief seems a bit short -- it's perfect for two-handed shooting, but if you try a recumbent position that allows you to stretch out your arm, you lose some field of view. Still, the little thing allowed me to shoot some mighty small groups with the old Ruger, when rested on the bench.
