The one that fits you best!

I'm curious, though... why are you dead-set on a Ruger? Do you get a discount on that brand only? Have you already handled many rifles, & decided that you like the Rugers the best? Do you work for them, or does a relative?

Perhaps I'm reading your post wrong. It sounds, to me, as if you're saying something like, "I'm buying a Ford in the near future. What model should I get?". In which case, we'd all ask if you were towing, hauling, dragging kids around, looking for great mileage, trying to pick up chicks, etc.

As for the cartridge, I'd suggest staying at .270 or below if this rifle will max-out at deer sized game. You'll shoot more often than you will with a larger cartridge, & you'll kill 'em every bit as dead.

Though you didn't ask, a 4x or 6x scope would be plenty, as would a 2-7 or 3-9. If you spend > $150 on your scope, you can get into some pretty good glass.
