What are your groups shaped like? A circle? An I? A -? Are they horizontal? Vertical?
That gun with the right wind calls should be able to break into the sub moa at 800 range. If its horizontally strung out you need better wind calls. Vertical you need a better ES. If its a wind issue I would look for a better BC. Look at the wind difference between a 215 and your 168. It is a pretty big diff. I would assume.
In general if you wanna shoot well past 500 you need BC way more than FPS. 800 isnt past the effective range of an 06 and in fact is well under it.
