The 350 is great, I've killed bear, deer, elk, and coyotes with mine. I have a Ruger 77 in 350 and load the Barnes 200 TSX with IMR 3031 and it is pretty hot, but really packs a punch. You can load it down some and it still kills like a house was dropped on the game. The recoil really isnt as bad as some say. Load it down at first and see what you like and work your way up. I think you will be fine. The 600 is a fun gun.
