RE: .308 or .270?
If you end up going to the M77 Ruger .308, see if Ruger offers an ultra light model in that caliber. I have the Ruger M77 Ultra Light .270 and it is sooooo sssswwwweeeetttt!!! If you're hunting within 200 yards the Ultra light will do the job and it is so easy to carry and manuever with in the brush. Be sure to mount a top quality scope, no matter what rifle you use.
