RE: .308 fans/owners?
I own 2- 308s, a Sako and a Remington 7600 pump. I can' t say enough good about the 308 as it has served me well for 24 years. Low recoil, accurate, easy to find ammo, and good selection of ammo if you don' t reload. I' ve killed everything from fox to moose with mine. Both of mine like 150 grain bullets but you can go up to 180s. I recently sold a 270 as it sat in my case.
However, if the truth be know, any of the calibers you mentioned most likely will work equally as well.
