I'm not usually drawn into discussions about calibres for deerstalking as i don't have as much experience as many on this sight, but, I did own a 6.8-06 (aka 270) for a couple of years and i loved it. I used to tell people that it was a 6.8-06 and i would get loads of interest or a wry grin.
If some one showed me there custom 6.5-06 i would be thinking why didn't he just buy a .270.
Ezzy.
