I have a 14x APV Mueller and the 3x12 prostaff. The Mueller I am happy with, it is clear and has not changed zero through 60 plus rounds while load development with 140 and 150 g .270. I can clearly see bullet holes at 200 yds. I will eventually put it on my 25-06 and put a 9 or 10 x scope on the 270. The pro staff, however is a different story. I like the adjustable turrets and mil-dot reticle, but the glass is not very clear and hard to focus. IMHO I would recommend the Mueller and not the prostaff...
