Im running a new to me B17 MGR. Absolutely love this scope and how accurate the clicks are. I have it on my 6.5 Creedmoor with a 20moa base. Im only getting 8.5 mils of elevation travel with the turrets. Then I only have 11 in the reticle for hold over. Is this typical. I have to max out my turret and still hold over when I go out there. I was at 1140 and dialed my 8.5 and then held over. I like to shoot a bit further so wondering if something is wrong or do I need to step up to a 30moa base. Thanks in advance.
