VX6 is damn fine scope, to my eyes (which aren’t great) can’t see difference between non HD and HD glass, having owned both. You can check you dial up by marking a tall cardboard box with marks at every inch & half inch from zero to 11 inches. Place the box at exactly 100 yards from the scope erector turret. Best to fix the rifle in a portable work bench and align your zero at “0” inches at top of box. Dial up 10 moa and check to see where your zero now sits. If it’s 10.5 in then it’s dialing moa, if 10.0 in then it’s IPHY. And it might not be either. Repeat a couple of times to get an accurate calibration factor.
