I had to DLP one Grizzly in my life. It was 28 years ago when I was only 19 years old. It took 4 325 grain hardened garrett lead bullets from a 44 Mag Super Blackhawk to keep it down. It was an injured 4 year old brown bear that was going after a elderly lady we had with us King salmon fishing.

Bears in deep brush bent on destruction can be hard to kill.

I have a 9 mm Glock but I don't take it with me for bear protection.
