    I would like some suggestion here. I have mounted a new scope and mounts and I am hitting the target 10'' high. Sideways is perfect, but even with the adjustment on the scope at maximum I can't bring the shots down far enough.

    What do I need to do, raise the scope at the rear with a shim? or what do you suggest.

    Waboo,
    Move this or have a Mod move this to Firearms accessories. You will get a good answer quick.

    Technical is for board operation problems and a place for more complaints than compliments. (If you know what I mean)

    Good luck solving your problem.

    I am looking for suggestions. I have mounted a Bushnell scope on a recently built Mauser 98 actioned rifle using a Leupold base and Redfield extended rings. I have sighted in with one of those Leupold magnetic bore sighters and I can place 10 shots in a 1" group at 100 yds. The best grouping I have ever had.

    The problem is the POI is 10'' high and the elevation is at maximum so I can't lower the POI.

    I used a Level Level Level for setting the rifle level in a vise and the base mounted likewise. The windage adjustments are set and accuracy is perfect, it's the elevation I am having trouble with.

    Do I have to shim the rear ring so as to raise the rear up thereby dropping the POI?

    Any suggestions are welcome.

    I allways keep a bunch of old credit cards and other plastic cards around for shims for scope bases. They work well. I did once buy a set of Weaver rings that actually had a low and a medium mixed in the box. The way they were mounted the gun shot about a foot high and couldn.t be lowered untill I noticed the slight difference in the rings.

    Shimming the front base will lower the POI.

    Brass shim stock is the old tried & true scope base shim material.
    You can also make aluminum shims cut from a beer / pop can.

    And as KenWP mentioned, take the rings off and make sure they are exactly the same.

    In case you need to go the shim route. MidwayUSA and others has them .
    A pack of various thicknesses cost about $8.

    Does the Mauser still have the stripper clip ears on it? It's possible the base was not positioned exactly right when it was D&T for it and it's sitting a bit high in the rear.
    Just a guess. It's also possible to be the wrong Mauser base.

    Yes the stripper clip has been removed and yes it's the correct base. However it may well be that the base is not sitting flat for some reason even though I did use a level to check it. I'll go back over all the mounting points.
