scope zero

[wolf]

I want to start using my 6mmppc for longer range shooting than past 250 yards .this may seem a silly thing to ask but anyway.i have a leopuld 6 to 20 on my rifle with quick turn turrets on it.
so say my rifle is zeroed at 100 yards and i need to hit a target say 400 yards away so i click it up a load of clicks then fire.say then another target apears at 100 yards so i click back down to 100 and fire.
what i am wondering is if the zero may have changed at a 100 yards or should this not be a problem with a quality scope such as a leopuld.thanks

You're really asking if the clicks are repeatable I believe. They should be but any scope can have problems. The only way you're going to know is to actually test yours. You'll want to take your time during the trial to ensure that you don't make a mistake that might erroneously cause you to blame the scope. It would probably help if you wrote down a prediction of your shots before you look through the spotter to see if it was a hit or a miss. A fleeting thought that you may have pulled a shot should be recorded. If you think it it's probably going to turn out to be true. Use factory ammo unless you're experienced with handloading. There's no sense in intoducing another variable into a scope trial. -Rod-

I've learned that with most Leupolds I have to go up several clicks past where I intend to be and then go back down to the correct place before I can be sure that the scope has responded accurately. Same thing for going back down! Others have encountered the same condition. Excessive backlash in the adjusting system?

I never encounter this condition with my Nightforce

thanks for the replys yeah i will just have to test it hopefully get a day soon when the wind dies down.

One little scope adjustment trick worth using,that I got from the late Dick Thomas of Premier Reticles), always do your final adjustment in a clockwise direction. When you turn counterclockwise you are depending on the spring that opposes the turrets to move the erector tube to its final desired position. Many times due to a weak spring or other problems with the system, this does not work properly. The solution is to go past your desired setting by several clicks, and then come back to it in clockwise rotation. This way the erector tube is being pushed by the adjustment screw into the spring, and you are more likely to get the adjustment that you are looking for. Give it a try, and let us know how it works. Also "exercising",running them through their range of adjustment) a scope every so often is not a bad Idea. A friend once had a major scope problem at a Benchrest match,and solved it that way,taking my suggestion). He went on to win a yardage that day.

I have three Leupold VX-III's. Two of them have the factrory installed target turrets and I use a Stoney Point elevation turret on the third. I am always dialing up and down in the field and at the range and I have never had an issue with a "wandering zero". Maybe luck, but so far so good.
