Straight factory? Probably a Tikka…..
I knew many would go this route, as they say YMMV......
The one and only Tikka I own is the most inaccurate Rifle I have ever owned, a 3to4 MOA rifle at best.
It shoots great now that I changed to a Bartlein barrel had the action trued and bedded.
As for straight factory the most accurate I have ever owned is a Winchester Heavy Varmint push feed in 220Swift, a true one hole rifle but wont meet the 10# rule
Under 10# a Sako AII 22-250 and a Remington 40-X in 222
