Just bought a S&B PMII 5-20x50 DT ultra short and I am now looking at the spuhr SP-4036 my question is should I go with the 20 moa version instead? It will be mounted on a 22 inch 6.5 creedmoor using factory loads, shooting distances 100-600 yards at ranges and for hunting. If I go with the 0 moa base will the scope have enough adjustment to get out to 1000 which I may shoot on occasion or should I just go with the 20?
