Re: Scope height?
I think personal shooting style and preference play a big role here, and there will be different viewpoints on the topic. I agree with prior posts that you will definitely require a different cheek rest height for different shooting positions for the long range precision work. For my LR rigs, I start with the assumption that I will be shooting from a prone position for the most demanding shoots, and set up my optimum cheek weld/ scope height for this condition. My preference is to mount the scope so the bell is no more than 1/8" from the barrel. This helps to keep my comb height as low as possible while maintaining a good cheek weld, and not having comb interference with the bore line/bolt clearance. I prefer an adjustable comb, or add a cheek pad since I have yet to find a fixed stock that fits me perfectly for precision work. Also, in the event that a prone position isn't practical, I have the ability to adjust the comb.
