Google "crow creek outfitters"

Mike Parsons is the owner/operator and he's a great guy. Tags are guaranteed through the outfitter in Montana, though they are pricey.

If that does trip your trigger and you don't mind a six point on one side rule (read: pass up 300+ class 5 x 5's) you can look into hunting British Columbia. I've been to BC twice with two nice 6 points to show for it. They scored (unofficially) 300 and 320 respectively. BC is a bitmore costly though.
