View Full Version : shimming scope mounts

08-01-2010, 4:17 PM
I hope someone can help me on this one. I recently installed a scope on a .308 mauser project Iíve been building. I used a 1 peace base mount and med height scope rings. When I went to the range to dial it in last weekend the windage was perfect but I was shooting an inch low at 25yrds with the elevation maxed out . I did some research and found a way to solve this problem would be to shim the rear base. I found a couple companies that sell the shims but read you can use aluminum from a beer can and make your own. Is that right? And if so approximately how many shims would I need to insert under the rear mount to correct my problem?

What bases are you using? Weaver makes bases for most Mauser models. Make sure you have the right part # for your application. On the shims it's trial and error

I cut a coke can into thin strips. I shim my Leupold to one inch rings on my Anschutz 1712, not because its maxed out but rather to center the windage and elevation adjustment.
depending on the quality of the rings, lapping them might help.

Whoa - before you start shimming you be best served to analyze the problem as what your describing is not the norm.
