I'm sure this is simple, but right now I'm stumped. Mainly 'cause I'm just not experienced at this sort of thing. I just had a good smith install a high end scope on a modest but good shooting rifle. The scope is a Swarovski Z6, the rifle is a CZ 550. I supplied the smith with CZ mounts. Yesterday I took the rifle to the NRA HQ 50 yd indoor range. After a fair amount of fiddling and head scratching I understood that the rifle is printing very tightly indeed, albeit 4" low at 50 yds. I cannot further elevate the scope as it turns out it is maxed out on elevation. I just don't understand how this can happen, other than some gross dimensional variation in the mounts which have the scope at a cant. But the smith is a thorough guy, and I have no reason to doubt that he did as he was supposed to do. What gives? What do I do about it? Diagrams and illustrations welcome!
