Home Forums Hunting & Shooting Gunsmithing Ran out of elevation adjustment when mounting scope............

I am mounting a Leupold 3-9X on a Colt Sauer sporting rifle, using Redfield 2pc. bases specifically made for this rifle and Redfield medium height rings. When boresighting I find that I have bottomed out the scope's elevation adjustment and the crosshair is just slightly high versus the crosshair in the boresighter. If the owner cannot zero the rifle when shooting it, what should I do to gain the necessary elevation adjustment to allow him to zero his rifle? Do the bases need to be shimmed to make them higher or have material taken off making them lower?

What does the crosshair look like in the boresighter?

Gun stuff 101: "Move the rear sight in the direction you want the bullets to go."

The rear sight in this case would be the eyepiece. If you need elevation, lift the rear base.

1) make sure its the correct bases are installed and if nessesary the front one is on the front and Back one is on the back.

2)Make sure you don't have your adjustments backwards.

3)if that doesn't fix things, center your scope and install with burris sig rings and ofset inserts.

What Malm said.
Seeing that they are medium and not low rings,that may throw the bore sighter off a smidge.

Ever try setting the rifle in a cradle so it won't move, take out the bolt and look thru the bore and center something in the bore at 100 yards and thenlook thru the scope to see wheer it is centered at.Usually this will get you within 4" at 100.
I have never had any rifle that the scope is centered on the cross hairs of a bore scope. To chcek zero I record where each scope is seeing on the grid.

Quick possibility - since most bore sighters are using a 1.5" value for height, measure the distance from the center of the bore to the center of your lens in the bell.. If the result is more than 1.5", it's very possible your bases/rings are fine - take the rifle out, shoot it at short range (like 25 yards) and work to adjust the scope to give you approximately 1" low from bullseye.. See if you have any room left then on the scope..
