Still planning on a trip to Alaska this fall for Grizzley/Dall. Getting ready to put together a back up rifle; CZ550 in 9.3x62. Have ordered a McMillan stock. Lots of advice on bullets; 250 AB 286 Part 250 TSX 286 TSX 250's should run about 2500 to 2650 fps 286's should run about 2350 to 2450 fps I've been given the impression, when it comes to the Grizzly, it's not the bones nor hide which will prevent lots of penetration as they are both fairly thin, it's the dang fat which will easily cover over the hole/s and stop the blood trail. "Complete penetration is the ticket" to give a two holes for blood trainling, if it comes to that. Any opinions on the amount of penetration needed and which bullet to use for the south end of a north bound bear if I screw the pooch and he's aways out there and still flipping mud clods into the air with all four?
