I've got a Ruger No.1 in 338 Win Mag that can shoot 3 shot 5/8" groups with Sierra 225 grain Prohunter bullets. I don't use these for hunting anything except deer and sheep, but the rifle will shoot the Winchester FailSafe's into 3/4-7/8" all day long.

While this isn't what I would consider benchrest accurate, it is very good for a rifle set up as a hunting rifle with hunting loads and a 1.75-6x Leupold scope in Ruger factory rings.

I should load up some Sierra Matchkings just for targets and see what it would really do.
