The Federal Fusions are excellent, as Mac hopefully will soon chime in to show his impressive group with them.
I have a 30-06UltraComp, and have found the Winchester Super-X SilverTips also shoot really good in mine. The 180gr's shot great at under an inch, and I am going to be trying the 150's soon. Core Loks didn't really impress me, about 1 3/4" groups consistantly at 120 yards=my range. I have some Federal Vital Shok 150gr's and some of the SilerTips in 150 also yet to play with.
Good shooting to ya, and enjoy the -06, it's a great cartridge indeed.
