It's really fun being a rifle looney and playing the numbers game, however please hold your hand up if you can truthfully can deliver a KILLING shot on a game animal smaller than an Elephant at 900 yards on a breeze day across a canyon. If you raised your hand you are lucky and 1 in a 1000, IMHO. Inside 400 yards the 270 has the edge, if only slightly. I own a 6.5 Creedmoor and am not really in love with it. It worked fine on the one deer I killed with it, just not that impressed. Example of one, I know. True the 270 used 14 grains more powder, but if I can't afford that I can't afford the gas to get to the range. In a blind test I doubt I could tell the difference in recoil in the field, off the bench the 6.5 has a slight edge. As a young guy I gut shot a fine Mule Deer at about 400 Yards and lost him to die a miserable death. NEVER AGAIN. I'll take the .270 with a good bullet and get closer, thanks. I have fun shooting at far away rocks on the distant canyon, but not on game, it's not fair chase.
Just my two cents worth on this fine Sunday morning.
