The .270 Win. has been getting it done for a long time and will never die, just like the 30-06 and several more. It's an amazing round.
I for one am into A.I.'s and other variants like the Sherman line, the added edges they offer are worth it to me.
I have a shoulder injury which doesn't care for heavy recoil, I had a 7 mm-08 A.I. built because I had a short action to build of off or I would have chose the .270 Win. My wife currently shoots a 25-06 for deer and antelope and a 7RM for elk. Don't you dare tell her a .270 Win. would fill the bill for both.
But I gotta admit it, if had gotten a .270 or ever do, it will get reamed or rebarreled into a .270 Sherman.
