Got a new scope for one of my rifles. I was sighting in the rifle the other day and my first shots were well off the mark. I was about three inches off target to the left. My scope is a Leopold VXIII 2.5 X 8. It has 1/4 MOA adjusments. One click equals 1/4" at 100 yds. The target was 100 yds away. Three inches equals 12 clicks. When I made my first rough move I moved it 12 clicks to the right. I shot again and was now hitting a couple inches to the right. I had to move the reticle adjustmments back to the left to get close to on center. Has anyone else experienced this before? It seems that the reticle clicks don't turn out to be 1/4".

What kind of rest are you using. If you are not using a rest you might not be hitting the same place twice so adjusting will take some more time and not always follow the rules.

ChesterGolf is correct but I use the adjustment as a rough estimate. They are close but not exact in my opinion

The first time I went I used a set of shooting sandbags and an adjustable front tripod. The last time i shot I used a Lohman Sight vise. It was not clamped too tight on the forestock so that the barrel still free-floats. Pretty solid set-up. These are all from the covered bench at the range. Shoot-n-see targets at 100 yds. I was thinking maybe the adjustments aren't really precise and there may be room for error. I also heard from a buddy that when he makes a move with his reticle adjustments he goes past the new position by one click and then turns it back one to get to his new position to relieve any tension in the adjustments. Ever heard of that?

No, I havn't heard of that, but I can't see how it would hurt either With a boresighter I've seen it appear that the first one or two MOA adjustments didn't do anything and then movement begins. Then you have to consider all the human errors involved etc.
The very expensive,German made Schmidt & Bender scopes may be able to lay claim to such precise adjustments but they are still five times more expensive than the very reliable Leupold.
And I don't know of a rifle that can claim anything close to what the scopes claim they can do.
I guess it just leaves more questions than answers

I'm with you there Hammer1. I think the dials are just a guide. From what I've seen on a couple of occasions, you don't want to make big adjustments and expect them to correlate. Once I get them adjusted, they seem to stay that way unless I introduce some other variables, like ammo.

That scope you stated was a VXIII so it should be pretty damn precise. That is one of the top of the line Leupold scopes and is no sucker in the accuracy department. I would be contacting Leupold about the situation and getting it looked after.

I'll give customer service a call and see what they say. It was a brandy new, fresh out of the box scope. It may be possible the adjustments are just "stiff"? No doubt it's an expensive scope. Cost $100 more than I paid for the gun new. And that's how it should be.

Let us know what they say. I'll bet they tell you that what you are stating should not happen and they will want to see the scope or exchange it for another.

I e-mailed customer service at Leopold and explained them my problem. No reply yet. I'll give them a little time. I bet they're busy this time of year.

Not sure what you mean by moving the reticle adjustments?? Leupold will be confused by your email also. That scope has windage and elevation adjustments. The reticle will focus for your individual close eye sight then lock in place via a tightening ring and that's it for the reticle.
What was the wind like that day? Strong cross wind? Calm? Also a whole lot has to do with how accurate you yourself are as a shooter (not saying anything bad about anyone here). The VXIII is an excellent scope. Those Leupold windage/elevation adjustments are very precise as to MOA. Every bit as accurate/precise as the German/Austrian stuff. Could be a defective one, but not likely.
I know two guys who were having similar "accuracy" issues with their rifles. One swears that his scope was not holding it's zero. He showed me his target and there were holes everywhere. You don't need to be a rocket scientist to figure out what the problem was. I fired a 4 shot group with his rifle from a bench and sand bag at 100 yrds and put all 4 shots in a 1.5 inch group that was 2 inches high and to the left. I made a quick windage adjustment and he was zero'd 2 inches high at 100yrds. Another buddy swore his rifle was horribly inaccurate. I did the same thing, but put 4 shots into a 1 inch group at 100 yrds. Hate to be critical of these two individuals, but it really boiled down to the fact that they just were fairly inexperienced shooters who really could not shoot that well. Not saying that this is the case with you in your situation, but there may be other factors at play here, such as crosswind messing with your impact or other stuff too.
Came across an individual at the range who was having some wierd accuracy issues with a used rifle he just purchased. He was frustrated and finally after seeing my targets, asked me if I would fire a few shots from his rifle because he was sure that he was not the culprit. I could not group them either. I later witnessed him to actually be a very good shot himself (better than me), and I could tell by talking with him that he had a lot of experiece shooting rifles. After inspecting the locking lugs on the bolt, the crown on the muzzle, I just happened to notice a slight looseness with the barrel to stock fit. Yup that was it, the action screws needed tightening and that was throwing off his accuracy somewhat terrible. The looseness wa so slight that he didn't initially catch it, as I barely noticed it myself. There can be a lot of factors at play when it comes to bullet impact.
Get a good solid rest and strap your rifle into it with velcro straps over the action and comb/stock. Use just enough trigger pressure to fire the rifle. This will give you more consistancy from shot to shot. For sighting-in I like to take the human element or error out of the equation. This will help to tell you if the ammo is inaccuare, the rifle is inaccurate, or the shooter is inaccurate. Can also tell you about the scope precision when making precise adjustments.
Once you are sighted in then get off the bench and shoot offhand from all the various shooting positions. Remember, sighting-in a rifle is not target practice. Shooting offhand is the real practice. Hope this helps.
