This is an awesome scope! I put it on my 30-06 and love it!  I was in debate on the 3x9-40 or the 3x9-50, I went with the 3x9-50 and am glad I did.  I have only range shot this scope out to 300yds and was impressed with how clear it is.  It's not as clear as my VX-III I have on my Ruger 280 but at about 1/10 the price it is well worth it.  I've put about 20 shots through my rifle and never had to re-zero it. I feel more than comfortable taking an Elk with this scope 300-500 yds, if I can't call them closer that is.
