The set-up you're using is MORE than capable of taking any black bear that walks the planet.
I run a Matrix 380 with only a few differences in equipment and would extremely confident at 60 yards.
Every single time.
Be sneaky. Be quiet. Get close enough, and ONLY shoot when the shot is right.
You will feel it.
Good Luck!
Looking forward to the tale & the pix!
