This scope is so awesome. It takes out all the fiddling and guesswork out of ranging and dialing. It's big and bulky but not having to carry a rangefinder pretty much negates that. The scope does everything, range, angle compensate, temp, humidity, pressure. It even has an integrated bubble level for left right cant. Longest kill shot I've had so far has been 500 yds straight downhill and the buck went drop in its tracks. It's also been spot on at 900 yds at the range. It's not cheap but in my opinion it's worth it. I wish they were smaller so I could put one on all my guns. In my opinion this is the ideal scope for western long range shooting/hunting. It is not needed for hunting close up less than 400 yds, way too overkill.
