I have a Savage Tactical .308 which i've recently installed a 10X SS scope on. This past weekend I had a chance to get out and really stretch out my shots, I shot at targets ranging between 200 and 750 yards. My friend had his rifle over and I noticed that he didn't have to make as many scope adjustments at the longer distant targets. He explained he had a 25moa scope base on his rifle. He to is shooting a .308 and I figured I would check into getting on of these bases. Can someone recommend this base or not? Also I understand that having one installed that your zero should start near 200yds. If i'm only keeping my shots between 100 to 800yds do I even need one?
