MTBA,
I was thinking maybe along these lines but just thought I would ask. What is the make of your rile and barrel? I am waiting on my rifle to get here, it is being put together by Charley Robertson in Arizona, a 700 action with a Shilen Select Match 24" in a 22-250. I really thought about going to the Ackley Improved, but little more power than what I wanted.
Sounds like you've got a good shooter there.
