My parents are looking into sending me on a bruin hunt for my graduation present this spring. Guaranteed 400-600# or better bruin or I don't pay. I've got a ruger mark II m77 in .30-06, and don't have a reloader (yet), what factory loads for my '06 would do the job on big boy bruins like these???? I think it's a baited bear hunt, so they'll be fairly close.
