I'm looking at the g7 and believe it is well thought out. Beside the items you mentioned is the reticle. I think it is an excellent idea. At close range, quick hold-overs can be used. For longer range dial and shoot, or dial and shot at all distances if one has the time.
There is a recent update on their site on the G7 Scope Reticle gseven - Final Version G7 5.5-22 Reticle
and the turret http://www.gseven.com/news/New-Balli...-Featuring-MOA
- <-- For some reason this will not operate as a link, on the Scope link, look to the right-hand side bar and there is a link there to the turret.
I like the idea of the turret having the custom numbering and moa scales. I wonder if there will be engraved turrets in the future.
I believe that the elevation correction can be handled fairly easily with grid card with elevation and distance. By developing a load and then deciding the elevation a majority of shooting will be done get the turret for that elevation and develop the card using their software (or any other).
Another option would be to purchase a couple or three turrets.
