[QUOTE="Bart B, post: 97533, member: 5302"] I've always zeroed my rifles at 100 yards, then used Sierra Bullets software to find out how much drop my bullet have at 100 yards. Then add that drop amount to the line of sight height above the muzzle axis for a correction. Finally I'd move the sight up in elevation moa an amount equal to that correction then rezero the adjustment knobs so they're at mechanical zero for that rifle. All this process does is zero the sights to the bore axis. I call it "dynamic bore sighting." And rarely does it agree with traditional "static bore sighting" by looking (or lasering) through the bore then the sights and converging them. Most folks don't believe how much difference there is. Anyway, after getting a dynamic bore sight, I use Sierra's software or range shooting to get the come ups for different ranges and altitudes. I'll tape 'em to the stock or whatever. And learning to count the clicks lets you keep your eyes on what the target and conditions are doing. [/QUOTE]
