Home Forums Hunting & Shooting Hunting Optics What do you all use for shimming material on scope rings or bases? And

where do you obtain it?

I have had the same soft brass sheet of shimming material for so long that now when I need to replace it I am wondering if this is still the material of choice for many, or if there is another material that is better liked?

Then, where do you go to obtain this scope ring or scope base shimming material?

I have a 10/22 lgiht varmint model whose reciever holes were put in just enough 'off' that I cannot be zero'ed, but it shoots such itty bitty groups I don't want to send it off and have it re done or played with by the factory.

Thanks in advance.
