I'd go minimum of 26" barrel. I personally chose a fluted Hart barrel, with a #4 taper for mine.
If your not into Savages that much, there are more options.
Instead of new, I've found its cheaper or a wash to buy a quality used rifle, like a Win 70, or REM 700 etc., & have it trued, & rebarreled. Seriously.
That leaves you the option to add a trigger, stock, whatever as you can afford it, or have your smith do it all at once while he's re barreling, & truing your action.
At last you won't run the risk of buying a factory lemon that way, & you have an excellent platform to go any direction you choose.
As far as glass goes, I find my 4.5-14x40 A/O Leupold VX-lll to be quite adequate. Plus there are a TON of upgrades you can do to em. I see them all over in the paper, & on Craigslist in the $400 range. Leupold still honors its 100% lifetime warranty no matter who purchased it. Plus you can send it off to the custom shop for reticle, & turrets for cheaper than a new one costs.
I also have a 4.5-14x42 A/O Burris on my 270WSM, & like it as well, but your stuck with whatever youve got. No upgrades available that I know of.
If you choose an 18 or 20 power scope, make sure it fits your hunting style.
I hunt thick & nasty, as well as far as I can see in the desert so I like having the option to crank er down in the dark timber, & open er up for shooting distance.
Just things to consider.
Good luck with your new toy
