3006 and "extreme" dont even belong in the same sentence... I would limit the 3006 to about 800 yards for LR hunting. A lot better calibers these days that shoot circles around the 3006 for both hunting and LR target shooting. That said, I've never owned, or care to own a 3006. It's just boring, and doesnt do anything really great, it just works ok for most everything. Not a bad choice, just not my first, or fifth, or tenth...The only thing I really like about the 06, is the many other variants based off the case, that seem to do a particular thing better.
