We have our share of bears in Alaska. The older I get, the more I prepare for them as I venture out on my hunts. For quite a few years now I've brought a shotgun to base hunting camp where I start out on backpack hunting trips. We will hunt ptarmigan around camp when the opportunity presents, for some added excitement.
The past 5 or so years I've also brought Brenneke slugs to base camp, for bear defense. Every now and then, we'll have to return to a kill site the following day to complete meat recovery. This is normally a caribou carcass. In those instances, I will carry my short barreled Rem 870 shotgun, loaded with Brenneke slugs.
Going forward, I'll be carrying what I consider the ultimate bear defense-of-life ammo. TSS buckshot.
This link leads to my post with further info on TSS buckshot. When returning to a kill site, the odds of bear encounters go way up. I want the odds for survival maximized in MY favor.
