I have shot antelope and coyotes with the G7 out to 1200 yards, along with countless first shot hits on rocks beyond that. While the G7 doesn't correct for spin drift or coreolis, they are straightforward mental adjustments that can be made very quickly given the effects have been understood beforehand using a ballistic program. For example, using my 6.5x284, spindrift between 1000 and 1200 is .5MOA left windage correction added to my wind dope. When shots get beyond 1050 yards I correct for coreolis. My latitude is generally constant where I hunt, I correct 1-2 clicks(considering the range) in the appropriate direction up or down for an easterly or westerly shot. Yes, really, it works.....and it is much much faster than entering values into a calculator.
