I don't think you can go wrong with either one of them for your intended purpose ... besides, it's not like it's going to be your last build. Whichever tickles your fancy at the moment ... I say go for it.
New bullets, powders, barrels, etc ... are changing the game tremendously. This include the mind sets established by of some of the early pioneers, i.e. Ackley, etc ...
I only have a 6.5x55 Swede for a .264 cal and is a carbine for them thick timber hunts. My current build in works is a .270 AI (just because lots of naysayers say I have nothing to gain - based on Ackley's book ... I'm sure I'll hear it from them
, case in point .280 AI vs .270 AI.
For me, I started with what bullet to use ... I will be taking advantage of the Matrix 165/175 and the upcoming Berger (170 ???). It's going to be on a Savage 110 LA with Lilja 30", 1:8, 3-groove, #6 contour ...
That's what is so great about America, we have plenty of choices to choose from. What we do with them is a different story. Will see how it progress!
Good luck and happy safe shooting/hunting.
