Going to Kodiak in a month and will likely be carrying my CZ 550 in 458 Lott. What bullets would you recommend as a strictly back up bear stopper. I'll be going with a buddy of mine who is doing the actual hunting, I'm just carrying a rifle in case we get into a pinch, self defense, type situation. Which if that happens I want to be able to bring it to a screeching halt. I also have a 45/70, a christensen ridgeline in 300 win mag, and two different shotguns, an 870 tactical, and a versamax tactical. If there is one of those you would recommend over the 458 then let me know. I'll have a 44 mag ruger redhawk in a galco kodiak holster as well.
