Some of you aficionados need to help me out on this one. Bought my "last" rifle a few weeks back. Got the Christensen Arms Mesa in 6.5 Creedmore. I won a Quigley-Ford at a game dinner. In order to get the scope, I had to contact them and tell me exactly what caliber and what load would be used in the gun as they "etch" the crosshairs in glass when they make the scope. I upgraded to their top of the line 5x20x50. Now at 74, my eyes aren't what they once were and I'm sure the rig can shoot one helluva lot better than I'm capable but I'm wondering if anyone else has experience with this scope.
