Savage99, I am more or less trapped into a 30.06. That's the minimum that is recommended for grizzly country. They've had a number of grizzly attacks in Idaho over the last few months as the grizzlies expand their range. I'm relocating to Idaho from the Southwest.
Initially, I planned to use my Marlin .30-.30 with 170-grain rounds. A friend from Montana told me that I was nuts. Everyone up there is carrying bear spray and at least a .44 Magnum for backup. The rifle calibers are also heavy. As it is, I'm probably going to have to get a Past Recoil Pad for my shoulder in order to handle the 30.06 recoil.
