Yeah, I don’t know about copper much for velocity. I wouldn’t choose the 6.5 creed for long range and copper just knowing the limitations.Really I would be most interested in a 22" which I am anticipating would get me about 100 fps more than the 18". Although the 18" would be handy in some of the timber hunting. I primarily run copper so I am trying to keep it in mind when I pick a rifle.
I agree I would go short barrel 6mm or 6.5 PRC if velocity was my concern and I hunted timber. I am gonna bring my SBR on all my hunts back east… no need for extra velocity at the sacrifice of maneuverability.
Also, I would buy a gun for the majority of my work, like timber. Don’t sacrifice 99% of the time for the once in a while western hunt.
Just deal with the reduced velocity in the west. Unless you are practicing a lot, you won’t effectively shoot much further than 450ish.
That’s my thought on that.
