Default Scope question

I have a new Leupold scope on a rifle in med seeking rings and a 20moa base. Today when sighting in I have bottomed out my downward travel and am still hitting 5moa high. I havenít had this problem before with different rings and scope on same setup and really not sure why itís happening. Is there any easy ways to correct it? Or just hold using milling reticle at 100 and have plenty of elevation travel for longer shots?

Not a long range guru by any means but with a 20moa base I wouldn’t be trying to sight in at anything less than 200.

Are you sure you don’t have the 20moa base mounted backwards? There is nothing wrong with zeroing the scope at 100 yards, especially if planning to dial the turret or use bdc reticle for longer shots.

The scope base is mounted in the right position, higher end at the rear of gun. Like I said weird thing is I’ve never had this problem with the other scope and rings I ran on it. Base hasn’t come off it is still loctited in place. Even if sighting in at 200 that’d still leave me high 3” or so.

Measure you ring heights next to make sure there is nothing funny going on there, and then that would only leave something wrong with the scope I would think.

Heís not. Itís an equipment issue. Which Leupold do you have? Iíll find out how much travel you should have. I canít think of any that should be bottoming out with a 20 MOA base and zero MOA rings.

Are you hitting the zero stop on the scope for some reason?

If I am reading this correctly, you changed scopes. The most likely cause is that the other scope had more internal adjustment. Changing rings could also do it. I've seen instances where a packaged set of rings were slightly different height. Doesn't take much. I have a rifle set up with a 20 moa base, and the original scope that was on it before installing the 20moa wouldn't zero at 100 meters.

What scope?

What's the mount on? I've seen a screw from a pic rail poke up and mess with a mount like this

Also if it's on a seam where there are joints in a rail

Itís a Leupold mk4 should be 65 minutes of vertical travel. Right now Iím getting 50. So I called Leupold and they said to send it in and they will check it out.

Thanks everyone for the help

That’s what I was thinking it would be. Unfortunately I’ve seen a few Leupolds that way, or with canted reticles. They’re pretty good about getting them back to you right though.

Did you "true" the scope? Dial it all the way down then count the clicks while bringing it all the way up then going down to half of that number of clicks?

No but I got it optically centered by holding a mirror in front of it then adjusting until the two crosshairs matched. Still didnít have enough vertical travel and horizontal travel seemed short as well.

Which scope? I believe you probably need to move your zero stop. I had a buddy with the exact same problem earlier this week.

They don't come set all the way at the bottom sometimes so you probably have more adjustment but you will need to loosen the set screws.

The one time I had this issue was with a Zeiss scope. After changing rings and bases 6 times, I finally figured out it was my Zero stop causing the issue. Your problem is obviously something else, but I can relate to your frustration. Only advice I have is to only change 1 thing at a time and then go shoot to eliminate the possible causes.

The only other option is to get it zero’d at 200 or 300 yards and then see where it shoots at your preferred hunting distance. You may be satisfied enough with the results to keep from messing with it.
