I know the twist rates, etc., are different, but my Savage model 10 in .22-250 1 in 12" twist shot a .250 group @ 200yds with the Hornady Superformance factory ammo.
On a similar subject I just bought an Axis in .223. With the help of NdIndy, Kaianuanu and dmpowder and their posts, I was able to get the factory trigger down from 6lbs to just under 4lbs. All for about $2 and 10 minutes of time.
