I agree on the .270, Ripp. My buddy's wife uses a .270 for everything now. It was Keith's Mom's rifle. Deer, bear (she has used a .358 Win.) moose and elk with good bullets that O'Conner never used (that I know of). She also got a really nice Kudu with the rifle, using a 130gr. TSX - 1 shot & down.

I agree concerning the 6.5x55, especially in a Swedish Mil. fast twist rifle being everything, power-wise, the 6.5 Creedmoor is today.
The only advantage the Creedoor has is in guilt edge accuracy, not needed in a hunting rifle at hunting ranges.
