Question for you long range hunters out there (500+ yards). This past season I had a very hard time ranging a couple of deer over the 500 yard mark. I resorted ranging the trees behind them and "guesstimating" how far out from the trees they were. Needless to say I missed...twice. My gun and scope are MORE than capable of making double that shot, so that's not the issue. My problem seems to be getting a reliable range. I found it impossible to actually range the body of the deer at that distance. What techniques/equipment do you guys use to get a range on deer at extreme distance? I can range with my scope, is that how you guys get a good range? Seems pretty unreliable. I have a vortex rangefinder if anyone was wondering.
