Zeroed at 100 but shouts 4” high at 200

[tbroz]

I have a 338 lapua zeroed at 100. Shot three different loads and with 1/2". Then I go to 200 and it shots 4" high and about an inch to the left. I go back to 100 and it's perfect again. Used a bench to shot from on both 100 and 200. Is there something wrong with the scope. This should be shooting 2 to 3 inch low not high.

What is your scope height?

 

[tbroz]

The scope height is 2". I used factory loads and hand loads the same out come.

Are you dialing up at 200 or just shooting same zero as 100?

 

[tbroz]

I'm not failing the scope. I'm even aiming at the same spot to see how much the drop should be .

A couple questions:

Are you shooting uphill or downhill on either the 100 or 200?

You mentioned shooting off a bench for both the 100 and 200. What were you using for a front and rear rest in each case?

4 inches is a lot. Are your groups at 4 inches high consistent? Is it walking or aer you getting a good group?

If you are not dialing the scope, it is not the scope. It can only be one of two things. You or the rifle.
Are you driving the rifle within your set up? Pulling recoil instead of allowing the rifle to recoil under control straight back?

Get someone else to shoot it and see the results. That will narrow down the variables one more step

Shooting on level ground . Used a cold well shooting rest. Has the rest sitting on the stock because I know sitting or touching the barrel can affect the shot. Someone told me the lens in the scope may have moved and the parallax has moved.

Make sure barrel is free floating and you are only putting the forearm on the rest, barrel can not be in contact with rest.

If a sporter barrel, it has to cool. My RUM was good for 2 shots and then it had to cool or my rounds started to climb up and left.

After that, how good is you trigger? And your form. Might ask a buddy to shoot it and ensure it is not the shooter. I have had an instance where a buddy could not get his gun to shoot at 250 so another person got behind the gun. Turned out gun was fine. Not saying this is the case, just trying to help isolate possible issues.

I would dial the scope down 4 MOA (to lower the point of impact) and shoot a 100 again and see where the point of impact is.
What scope are you running ?

 

[tbroz]

It's a bushnell 5x18 tactical. About ten years old. I did not let someone else shot the gun normally I'm the one that has to shot everyone else rifles because of problem. I did let it cool down as well. I do find I get tighter groups when it's warmed up. And yes I made sure I was on the stock. I normally can shot beer cans with my m14 out to 360 yards. So I don't think it's me but never know. I did mention the issue to bushnell and they said they will just replace it with the new Elite Tactical 6-36x56 XRS3. Trying to see if it is the scope or something else

I would wonder if your 100 yard hit is the "first zero" shown in the picture below, not the second. Usually the bullet crosses your line of sight around 50 yards out for the "first zero."

If you check your point of impact at 25 and 50 yards it might tell you.

when I first got the gun I bore sighted it at 50 so I can hit the paper and not waste $ then went to 100 to fine tune. You maybe right
