    I shim bases if elevation adjustment is needed. You can make them out of beer cans.

        Never measured them. I've got a big stash of shims Leupold sent me when I mounted scopes at Cabela's. Before that I had a stash of homemade shims. Some were from beer cans and some were from soda cans. Beer cans are thicker so that gives you two thicknesses of shims to work with.

          We use beer and soda cans but they are not very thick. This requires quite a few shims to get any slope.
          Burris sells clear plastic shims that you can get in different thicknesses. I tend to get the thickest ones they make. They come in packets of 10-20 shims and are very cheap.

            You shim the bases to get "slope"? You're going to bend your scope doing this. The stupid gunsmith did that to a scope I bought second hand and that's what I now have. I only discovered the bent tube after I removed the rings that came with the scope. The gunsmith used his business card as a shim.

              Until recently I would only shim a one piece base which will not stress the scope tube. Last month I was talking to a Leupold tech and their policy is that it is find to shim a two piece base with up to three of their shims. I waited a day, called back and talked to another tech and received the same answer. If I absolutely have to I will now shim a two piece base.

                You can shim bases to create slope, then ream/lap the rings to get rid of the misalignment that the shims created.
                If you do NOT lap after shimming, then you can get scope tube damage.

                  the real answer is none, especially if you are talking about long range BR. I would even say that shooting f-class for a BR shooter will make them better from a wind rea ding perspective. none of the guys who shoot long range BR who cross over to f-class do any better or worse than a f-class shooter. it's the wind that equalizes everyone. our guns do not shoot anymore different than a BR gun.

                  when you drop only 7-12 points total over 2 days, with (5) 20 shot strings, what more can you expect from a gun? my dropped points came mainly from wind calls. so let's say even half of those 11 points I dropped at the CA state were to vertical, that means 6 shots out of 100 slid into the 9 ring at 1,000 yards. and those vertical shots could have been conditions too.

                    Do you know how big a 1000 yard Benchrest target is compared to a F-Class target?
                    I agree guys like the late Jerry Tierney, Peter White or Gary Childs shoot both disciplines well but you can't compare F-Class scores with Benchrest scores because the F-Class target is more than double the size of a Benchrest Target.

                      So, this is where I'm at. I followed one of the videos from earlier and I couldn't fit even a piece of paper between the scope base and the receiver, so I don't think I'm gonna have to bed or at least bedding would have minimal effect, I think, I'll leave that for ya'll who have more knowledge than me. I went with a badger ordnance base and badger ordnance standard height rings.

                      I got a Bell and Carlson M40 stock coming as well as the badger ordnance m5 dbm

                        Yes, I know. I see the targets. But, you also shoot all 5-10 shots in hopefully, the same wind condition, without delay. This is huge! You do ELR shooting. Every second you take between shots is more opportunity for the wind to change.

                        For you to say that a 700 action could make you a HM, but not hang in LR BR is pretty offensive and is indicative of what you think about F-Class and its inferiority to LR BR.

                          There is a HighMaster in my list so it isn't what I think it is a fact.

                            Were there any thoughts, concerns, or criticisms with my setup? Any tips/tricks that I'm missing or would be useful?

                                I gave my opinion and you are still asking for more opinions which tells me that you didn't value my opinion much if you have not already ordered the parts.

                                You need to figure out who YOU think the most qualified people are to listen to and then order the parts they recommend.
                                Listening to all the less-qualified opinions just makes it harder to decide, ultimately obfuscating the better advice you have already received.
