I have spent a lot of time in Alaska. I have been chased by 2 moose and zero bears though i have seen many many grizz and blacks. one moose chasing was a very close call. I would take the .40 with a good hard cast bullet and rock and roll!
If you run into a griz or angry bull moose, either gun you own will not be enough anyway
Actually, I am very good with a Smith Model 66 (4"), but it is pretty much a safe queen. I know, you are now all thinking that the 66 is the best option, but it's just too perfect to take into the woods.
Ok, ammo? Buffalo Bore is better than DT for the woods application? The 180gr BB better than the flat nose 200gr DTs that I have??
