Onehorse - read them all. Very well presented.
I really doubt that I will be taking a shot beyond 250 based on my recent experiments with the range finder. Since there are only 2 stands where this distance would be necessary, I plan to use the range finder to measure certain landmarks and base distances on those. With the rifle zeroed at 200, the most I think I would need to do is keep it mid/high on the brown to be effective, if those are the ballistics that the rifle demonstrates on the range.
Finally, once sighted in, most of the practice will be off the knee pod or the equivalent of the gun rest on a buddy stand.
