I have a Savage long action, flat back reciever.

It has an EGW 20MOA one piece base, Burris Z rings. It was originally set up with a Grand Slam 3.5x10x50 scope and was dialed in pretty well.

I took it apart to install a SSS trigger. While it was apart I removed the scope and rings to swap the scope for a Leupold VXIII 6.5x20x40 scope that I had previously used on an AR.

I did not touch the EGW base.

Now I can not seem to get the elevation set. At 100 yards, I have run out of "UP" elevation adjustment and I am still about 8" low.

(It worked fine with the Weaver.)

I have taken the rings on and off a few times and carefully reassembled the scop and rings. I tried swapping front and rear rings as well as turning them 180 degrees. Still no joy.

Any ideas? What am I missing?

I am going to try swapping in another scope that just came back from Leupold for a reticle change, but was hoping to use that one on a different rifle.

I am sure I am missing something simple.

Any suggestions?

Thanks.
