[QUOTE="Hugnot, post: 2584464, member: 115658"] Elevation differences of 1000 to 3000 are no big trajectory deal at 500 but what matters a tiny bit more is the actual barometric pressure and that also is no big trajectory deal. Looking at the entire spectrum elevation, pressure. temp & humidity (damp air is nice) at 500 would be no big deal with a zippy velocity bullet. Sight your rifle in during a warm east coast muggy day then go to the arid western mountain October-November hunt and the trajectory difference of less than 1 inch would be far less than up-down group variations. Like mentioned a 1 click (.25 MOA) would work out nicely. More important is shooting up or down hill - like is common in the western states. A cosine table works real good. Some rangfinders can provide firing solutions. Trajectory differences due to moderate inclination variations can cause a miss of up to a foot or more. Use Google Earth to get some idea of terrain, like how far up or down might a shot be. Rocket scientists would agonize over enviromental conditions should the target be a golf ball at 1,093.6 yards.
