RE: Out of the box accurate bolt action
It depends on what you consider to be "accurate".
If you're content with 1.5" at 100yrds, pretty much any Ruger, Remington, Savage, Sako, Tikka, Winchester, H&R/NEF, Weatherby, Vanguard, Howa, or browning will get it done for you...even several Marlin leverguns will...and yes, these are personal observations, not just what I've heard. My hunting buddies and I try something new about every week.
When it comes to beating 1.5MOA, things get a little more scarce...from factory guns, this is going to depend on the individual gun and the load you're running in it. I've got a Ruger Mark II M-77 .30-06 that will shoot snowmen at 150yrds with the right ammo (Winchester Supreme Balistic Silvertips), with the wrong ammo, it's a 15" group (yeah, 15") at 100yrds (Winchester Super-X power points).
I've bought two Remington 700PSS .308's, out of box one would put five rounds into a 0.5" diameter hole at 100yrds (.2MOA), the other ran about 1.2MOA...of course, it was going to be a target rifle anyway, so it got a full action and stock job (I left the first one alone!!).
I've also had a Savage .22-250 12FVSS (with the Dragnov stock) put five rounds under a nickle at 100yrds out of the box.
Savage is a contender for the most accurate production guns out there, even before you consider their price. They are hands down the most accurate gun for the money. Who needs a gun to be pretty, I'd rather it shoot well than look good.
