Resetting Zero:

RE: Resetting zero

If my rifle is zeroed at 1,000 yards, and I dial in the necessary clicks to get the crosshair "on" at 300 yards, and THEN I want to dial in clicks to get the crosshair zeroed at 600 yards, do I use the number of clicks to get to 600 based on a 1,000 yard zero, or 300 yard zero? I thought if I backed off from a 1,000 yard zero the required number of clicks to get to 300, that I would just backtrack (go back up) the required number of clicks based on the 1,000 yard trajectory chart to get a 600 yard zero. However, if I must add the number of clicks based on a 300 yard zero, the number of clicks it takes to get a 600 zero is much higher than if I was working from the 1,000 yard zero. I thought I had this stuff all figured out, because when I clicked down the required number of clicks to go from 1,000 to 100, it was right on. THEN, when I clicked in the required number of clicks to get from 100 to 300 based on my 1000 yard zero THAT elevation change was right on. But I am not so sure about going from 300 to 600. Anybody else confused?

Scott; Pro Snipers may have a better method and I would like to hear it but I like to always dial UP from 100. If I understand what your saying. I would go from 1000 to 100 and back to what ever range you want. If I had come to 300 and wanted to go to 600 I would just add the 600 clicks to 300 and move on up. This tends to eliminate any backlash in the system. A good sniper scope won't have much backlash but it might be significant in LE work where a half inch of scope click could be important at close ranges. I might add that the same can be true of variable power scopes. I always try to set the power from the same direction (going up in power) as backlash there will also affect the zero. Most Snipers tend to shoot at highest power would be my GUESS. I prefer higher powers even on running shots at distances beyond 100 meters or so but that's another story.
