After reading about every single post on this and other forums on the best brown bear rifle, I'm left very confused. I'm anticipating buying my new gun for a 2010 spring bear hunt so I can begin practicing with it. I currently shoot a 30-06 and am very comfortable with it. I've never shot anything larger.
If I can use a 30-06, which my guide says "is fine" with a 220 grain premium bullet (he says he even carries sometimes), then I'd prefer this since I have the weapon and feel comfortable shooting it. I would say there are about 25% posts on the forum supporting the 30-06...the AK Kodiak wildlife site seems to advocate the 30-06 as opposed to larger calibers, saying that it's fine for killing coastal brown bears...
...then, there's the others who say the 375 is a necessity! I guess my biggest worry would be if I happend to get a bad shot (which can happen no matter how good you are), say a gut shot for instance, is it more likely the bear will get away than if I was shooting a .375? Since I'll be hunting with a guide "I'm" not too worried about a charge (my personal view) since I will have backup and I think the best way to avoid such occurrances is just to be smart.
So, that said, should I go with the 375? If it's a must I will. My guide says no, but many say yes. Anyone out there in the real bush who hunt brownies use a 30-06? Any guides out there who have any opinions?
