Personally I would not hunt with a guide who didn't carry a backup heavy caliber rifle in Bear Country. With a very respectful response to Mr. Dogz, It's not how many times you didn't have to shoot at a bear trying to do you harm, it's that one time when it's needed that counts. I personally would not like to be made into a meal for a cranky bear simply because the guide (or myself) did not have a firearm capable of putting a grumpy bear down at close range. My 300 Win Mag is used primarily as a target rifle these days, but is also perfectly adequate for use to put down an unhappy bear.You've been there and done that a ton load over the last 2 decades that's pretty darn cool. Question for you if you don't mind, but how many times have you fired your rifle in defense at close range on bears that were set on doing you harm?
Many thanks
