The OP's in Alberta, Canada, possibly Rural and can't seem to find,.. WHAT he really, .. "wants",..
I don't know, the answer to your, Question. Seem's like, he's going to,.. "Make Do" with, a 6.5-06 !
YES, Expert "Hunters", aren't gonna be, "to Fancy" but, the Deer are, quite Big up there and, a .223 AIN'T,.. gettin IT for, him !
Personally, I'm NOT, to Fussy on, a Deer Rifle, Cartridges and the 6.5-06, .270, .280 ( Ai or Regular ) are, ALL,. "Good",.. IMO !
