Just for arguments sake if a .243 and a .223 are cool why wouldn't a .270 be? Myself I've never even fired a .270
The .270 is un-cool simply by virtue of the fact you and I have never even fired one....
There doesnt need to be any other reason....
120 yards, through the wingbutts, DRT & no meat damage. 130gr Ballistic tips, 60gr R22(max), sub-MOA at 3165fps. The 2nd load I tried in it. And it has nice wood.
