I can see an issue with the Bog death grip on a tripod when it is used to pan on an uneven surface. While the rifle may start out with the scope bubble level depending on the length of the pan and the uneven nature of the ground the scope certainly will not be level when it comes to bear on target. Bog advertises an Infinite ball head that it supposed to fix that issue and I'm wondering if anyone here has used one of those heads in the field and can give feedback. I have three varmint bolt rifles that I target chucks from point blank out to 600 yards with and details are critical. Thanks in advance.
