I have one on a 6.5 creedmoor, and for hunting, it's absolutely great. I've tested it out to about 800 yards, and it adjusts accurately as far as MOMD (Minute-of-Mule-Deer) is concerned. I would never use it to compete or if little baby groups were the goal. I talked with Leupold CS when I ordered my custom dial, and they said whatever parameters you give them, you should be able to hit vitals within a certain range of those parameters (I.E. +/- 20 Degrees in Either Direction of your temperature, +/- 2,000 ft in elevation in either direction), and that seems to have held true when I've tested mine. But again, I haven't shot a REALLY long ways with it. I will say, I have loved it as I've been learning to shoot to longer ranges. It has taken out one element of the guess work with learning my adjustments, and has allowed me to concentrate on just shooting. Is it perfect? Nope, not anywhere close. But it's great for hunting and for people just learning to shoot further. Any new rifles I get will get something else for optics, but this has been great for what it is.
When I punch in numbers on ballistic calculators I get a POI change of about 2 inches at 500 yards with 65 degrees of temperature change and 8000 feet of elevation change. I can't imagine that matters to the average hunter. That was spread from 5 degrees to 70 degrees and elevation from 2000 feet to 10000 feet. What am I missing?
