[QUOTE="SilverbulletMAG, post: 1549644, member: 108181"] As others have already mentioned, it does make a difference but shouldn't be so much of a difference that it causes you to miss if you were otherwise dialed in. As you go higher in altitude, you get the equivalent of a higher BC bullet so, if you're shooting longer ranges, you will want to take all of that into account. Plenty of ballistic calculators out there that will allow you to enter altitude/atmospheric conditions and plot out the differences. From my own experience, I routinely shoot at 9k elevation and have all of my rifles zeroed at that altitude. I head to MN for whitetail hunting every year and when I re-verify my zero upon arrival, I'm always 1/2"-1" low (depending on caliber) shooting at the lower elevation. Other conditions come into play of course (temp, barometric pressure, etc) but I know to expect that slight drop. Inside 300 yards though, not a big deal. [/QUOTE]
