[QUOTE="trophyhusband, post: 1126553, member: 70376"] I need a little help here. I just got a G7 BR2 rangefinder but It doesn't give me the right correction for my 6.5 Grendel. It does, however give me the right correction for my 300WM. For my Grendel, Strelock always puts me about 4 MOA low at 1000 yards and the G7 BR2 puts me even lower. All ballistic programs I've looked at give low to varying degrees so I'm convinced that this is a bad input=bad output situation. My question is this, should I adjust the muzzle velocity down or the BC down, or something else I'm not thinking of to get it to come out right? I don't just shoot this at 1000 yards, but occasionally out to 1200 yards and sometimes I like to move in to 500 yards. I also want to hunt deer with it so whatever input numbers I fudge will have to give me an accurate output across all ranges. [/QUOTE]
