I'd say that you shouldn't have to be concerned w/BIG critters or arguments over the gut pile with them.
In parts of Eastern Idaho its a different story:eek: The griz have learned to come to the shot knowing that sometimes there is a nice gut pile waiting. That's why its good to "gut and get gone".
My research on this forum says that a 45 Long Colt in Ruger Blackhawk, 5.x" barrel w/310gr hard cast bullets loaded to around 1000fps is just the ticket.
Nice to carry, nice to shoot, and has plenty of frontal area w/some umph...
