RE: Need help picking out a .270 cal rifle
I'm a Remington guy so I say go with a model 700 of your choice. I've got stainless SPS's and XCR's and I love um. I would then throw a Leupold on top of it. The vx-1's are good scopes, but buy a vx-2 or 3 if you've got the $. 3-9x40's would be fine (3.5-10x40 if vx-3). Sounds like your runnin factory loads so I would go with a stout 130 or 140gr load(ie-Accubond, Interbond, Partition, Grand Slam, TSX).
Asfar as the .270 goes, it's a great choice as a western firearm. It'll do all you ask of it if you do your part.
Good luck,
Brett
