I have a Sako Vixen wearing a Hart barrel in the Sako contour. Nice light rig for a walking groundhog rifle. With an old 6x Swift scope, it shoots sub-1/2" groups all day using 50gr Blitzkings and 20.5gr IMR4198. Wally Hart recommended 21gr but that works better with 50gr V-max bullets. I'd go Hart and be done with it.
