I'm using the 7mm Berger 140 VLD Hunt exiting at 3250 fps, EASILY good (devastating on light skinned game) to 500. This rifle is zeroed at 275 yards which gives me 3" high somewhere about 175 yards and 3" low about 315 yards (I have it written on a DOPE sheet taped to the stock and am not going to go verify exactly) so the vast majority of hunting shots are just point and click. I've verified the stadia lines in the Swarovski scope out to 1000 yards and have those yardages written on that sheet that is taped to the stock. If I can guess the wind, which I'm not real good at, it's not hard at all to get a less than 1/2 MOA group or first round rock kills. I kill lots of rocks.
