I can't answer your question about the rifle, because I only archery hunt in griz country for deer/elk. All of my elk except one have been killed with a bow, one with a muzzleloader. My point on reading (books/magazines/websites) is knowing your game animal whether it is a griz, blackie, muley, elk, cougar, etc., I am always reading in an effort to learn more, even though my knowledge base may already be high on a particular species. OK, you are bullish on firepower, thread started with a pistol and the rifle was brought into play, but what if you unload your rifle and/or pistol and miss and the bear is still charging? What if you shoot and hit the bear a couples times only wounding it and it is now madder than heck? You are now about to be mauled holding an empty gun...........what is plan B now? Maybe your buddy comes in a blazing and hopefully doesn't shoot you. Killing a charging grizzly before it gets to you with a pistol or rifle is not a done deal once the lead starts flying in my opinion. But, since I have never been charged by a grizzly, I can not say for sure. Only thing I can say, is that I have been in several life threatening situations, car wrecks (never my fault), almost drowned in the ocean and been scared for my life in a couple third world country confrontations and keeping my head, not over-reacting, having a plan, got me through some tough, potentially fatal spots. I have my plan if ever in a griz confrontation, it is a three part plan and yes I learned alot from some of the research that I have done, will it work, will I stay cool and keep my head, hope I never have to find out, but future trips to MT and AK are in the works, so only time will tell if I ever run into a griz or two.
