I have been in a face to face with a big black bear. It had a radio collar on, stole my food bag and came back for me. We were 6 miles in the new season for campers.
Long story short, the angry bear took my food and ran across a 10 foot wide shallow stream and up a hill. I chased it all the way to the stream. It came back down pissed all to hell.
Across the 10 foot stream we stood, me chucking rocks and sticks at the bear as it tried to cross the stream. It was 5:30 PM and getting dark fast. This bear was angry and at times on its back legs making all kinds of noise.
So it had enough of the rocks and it started across at me. I pulled my S&W Model 65 loaded with 158gr PMC 357 mags and fired off a warning shot into the stream bed. The gun went 'click'! WTH! I had a factory dud from PMC. Darn those Koreans!
The bear watched me as it was half way across, about 12 feet away. I lowered the front sites to its left ear and readied for 5 quick shots to its head, noise and eyes.
Just before enough pressure to the trigger, the big bear backed off and went back up hill to my food. I ran back to camp and throw everything into my sleeping bag and ran up the other hill to the trail. I looked back and saw the bear run back down hill to my campsite.
6 miles in the dark, lost the trail twice, crossed two large ice cold streams and found my car. Safe.
Did I do all the smart things? No. Was I under gunned? Yes. I did my best I could kept my head and acted fast, and got home alive. Would I do it again? Yes I did and but now with my S&W 629 5" 44 mag with 300gr hardcast Hammerhead Bullets.
I have enjoyed backpacking most of my life here in the USA and all over the world. Life is fun and exciting.
