Hi. I am new to the forum, but have been following the posts (very informative thank you) . One in particular interested me. Adding extra moa's to Sako optilock rings. I tried to view your pictures, but could not see them. My question is that I have a Sako TRGS 338 lapua and Sako optilock Rings. I did the set up as I thought it was described. I added One washer between the rear ring and the base. It should give me 45 moa's. My question is will the plastic inserts help the scope so their is no unneccesary torqe on the scope, or do i need to do more than just Shim the rear. Thank You so Much for your input.
