I have recently seen a lot of posts expressing concern that the taller ring height required for our chassis is bad. I would like to put that into perspective for some guys so there is a better understanding of what effect it really has.
As a shooter that primarily shoots long range, I have never experienced the negative effects of the taller ring height. I have 2 ranges that I shoot at. One has a maximum range of 3003 yards and the other 2930 yards. Our closest steel at any of these ranges is 1000 yards. When I see guys post about this negative effect I think to myself that they have never really shot long range or at least never taken the time to see the real affects of this added height.
The idea of getting the scope as close to the barrel as possible was originally meant as a way to get the best cheek weld with a non-adjustable stock.
I do understand the logic of cant in relation to scope adjustment and bore center-line. But lets take a look at the actual effects.
As an average, I would say our chassis require a ring height that is .350" taller than a traditional setup. Of course this depends on your barrel contour and how close your scope was before. However, for the benefit of this discussion, lets say the difference is .350"
I plugged some numbers from my Chey-Tac into JBM. I zeroed the wind and added 5 degrees cant into the calculation. I then changed the scope height by .350" to see the difference. At 1760 yards (1 mile), the change in height accounted for about .1 inch per degree of cant. That is inches at 1760 yards not MOA. That means that if I had 5 degrees cant then I would be affected 1/2 inch at 1 mile. I personally cannot shoot that difference. If you can, I would love to come shoot with you to learn something. I think the advantages of the hand guard/chassis far outweigh that difference. To put that change into perspective, a 1/2 mph wind will move my bullet 5.4 inches at that range.
I can assure you that our chassis have plenty of adjustment to account for the ring height and allow you to get properly setup behind the rifle.
