I am building a 6.5-284 mostly for varmint shooting and some minor competition. 700 long action, Krieger barrel with a remy varmint taper, nightforce scope. I was leaning towards a leupold base with burris signature rings with the 20 moa inserts. I expect to shoot 600+ yards maybe out to 1000. Now I am having 2nd thoughts. I dont want to spend all the money on the rifle and scope then put them together with an inadequate mounting system. You can always spend more money, but not sure of the benifits. As long as all is secure the leupold base and burris rings should work, and I like the inserts not leaving marks on a 1200.00 dollar scope. Suggestion?
