Years back, I had the honor to hunt British Columbia coastal grizzlies with famed guide Clayton Mack.
If memory serves, at one time, Clayton had guided hunters who had 3 in the B&C top 10.
I shot a nice bear, but I did so with a rifle.
The hunting was walking up small tributaries and basically coming into very close contact with grizzlies while they were looking for salmon.
For example, my dad killed a giant B&C male, again with a rifle, but at literally 10 yards.
Personally, I wouldn't care to do so with a bow, in that style of hunt.
Clayton Mack was a Bella Coola Indian and obviously had great respect for bows. But even he wouldn't take bowhunters after a while.
He spent about 6 months in the hospital after a mauling and he said he'd killed too many bears at this feet, as the backup gun, to do anymore bowhunts.
Personally, having done it with a rifle, in that style of very close quarters hunting, I would not want to do so with a bow.
Many fishermen in Alaska have had contact with more "tame like" grizzlies and they are used to human contact and not much of a problem.
Where we were in Bella Coola BC, the bears weren't tolerant of humans.
In all honesty, we had a couple instances with smaller grizzlies doing a false charge where I was nervous with a .300 mag in my hands. Again, just me personally, I wouldn't care to do it with a traditional bow. I have a wife and 4 kids I'd like to see again, and hug with both my arms.
