[QUOTE="J E Custom, post: 433685, member: 2736"] Nothing wrong if you are shooting 1500 + yards only. The problem with big MOA bases is that you can't zero at normal hunting distances. Most top end scopes have a 80 or 90 MOA total range so if you use a standard base you will be somewhere in the middle of the turret range and if you want to shoot 1000 yards 40 MOA=approximately 400 inches at 1000 of come up. If you place a 40 MOA base on a rifle to start with your scope will have to be at the bottom of the turret travel and end up approximately 40" high @ 100 yards. For most hunting rifles 0 to 10 MOA bases work best and keep the scope in a good operating range. So if you place a 20 MOA base on a rifle with a scope that has 95 MOA built in that will give you 65 MOA total up from a 100 yard zero for the scope(20+45) . 65 MOA at a thousand yards is 650 Inches of come up.Most rifles only need 300 to 400 inches of elevating to hit. What I recomend for base MOA is to look at the drop from 100 Yards to max to be shot based on bullet performance and skill, and find a base that keeps the scope in the middle of its range without bottoming or topping the turrets out. I hope I have explained the need to pick the right base for best performance. this is a place that bigger is not necessarily better. PS; If my math is off feel free to correct me .
