Opposite Pole,
This has been a subject that is sort of near and dear to my heart. I had never really had much fear of bears in the wild, and always thought seeing them would be really neat, and I still do...as long as it's from a distance. Last year however, in preparation for my moose and caribou hunt in the Northwest Territories of Canada, I found out that a moose hunter, guided by the same outfit I was hunting with, two years prior had been killed by a big mountain grizzly while he and the guide were breaking down a big bull moose he had shot that day. The next year, another bow hunter that was hunting for moose was up on a ridge glassing and calling for a bull with his guide. A mountain grizzly came from behind them out of nowhere and attacked the hunter and mauled him very badly before the guide could scare the bear away with his rifle. Both of these happened the same week of September in back to back years, and in the same remote area of the concession. And to add a cherry on top, I was going to be hunting that same week in 2016, and in that same area. Needless to say, I became very concerned.
I began to read that the bears encountered "up close and personal" in that area were starting to become more common over the last several years, as they have not been legally hunted in over 30 years. It's such a remote area that many of those bears had never even seen a human. I emailed the outfitter, and he was very upfront about the attacks. It had been 40+ years operating in those mountains without one serious bear incident, and then they had 2 very serious attacks back to back. When I arrived in camp, there actually was a gentleman that had been hunting that week the hunter was killed, and the story was terrible for sure as far as the details of the incident. Actually both attacks were freak, but terrible things....
Anyways, I started obsessing on the merits of bear spray versus firearms. Most of the "experts" feel that bear spray is more effective if only because most people don't practice stopping a charge (bear, leopard, lion, buffalo, etc.) with a firearm and bear spray gives you a broader pattern to hit with. The problem with spray, just as with a firearms, you don't really deploy the spray until the bear is within a 30 foot radius. And as fast as a mature bear can close on you (sprint 35 mph), it's not an easy proposition. As an aside, the guides up there giggled at the idea of bear spray. They all called it bear "picante", and said they've even witnessed bears licking the stuff when it's been sprayed in an area. They all carried lever-action 45-70's loaded with heavy bullets and iron sights. In the end, I chose to carry both bear spray and my 338 Win Mag. I had even entertained taking my Ruger M77 in 375 Ruger, but opted to stick with the 338 only because the shots at caribou can be a little long. We were close to bears every day up there, and saw several. Lots of sign every where you looked. We had a close encounter at 20 yds on the first day with a grizzly on the way back to our spike camp, and it bluffed charged us before turning and running off. I never really saw the bear until we had walked past it and heard it behind us. When I turned around, it was standing on its hind legs looking over the chest deep willows at us. It then dropped down, and eventually ran off. The guide and I had our rifles ready, and had we been able to get a good look at the bear before it broke off the charge, we would've shot it.......I'm glad we didn't have to because it looked to be smaller (maybe a 2-3 year old cub that had been kicked out by mom?) So much for the bear spray.......
I recently read this article by Anthony Accerano (?) in Sports Afield regarding this very topic. Pretty good information in it......
