what are you currently using to hunt deer "around here" with?

what might you hunt in SAS? or MT? elk I assume...

without knowing more info and you saying you want knockdown power I'd look to the vanguard in .300 WSM or .300 Weatherby, though a vanguard in .270 WSM would not only be a smoker for deer and ultraflat it could do the job on an the occasional elk down the road in the future, but if you already have a deer rifle, why bother with another,a .308 .30-06, get a magnum would be my suggestion.

a .300wby with 200gr bullets suggests "knockdown power" and could handle all of NA quite well.

I think you might be needing a ".338" though
