Gotta throw in with Flathead on this one..223 and Grizzly should not be in the same sentence BTW.
Should be considered a grammatical error.
I've had three very close encounters with grizzlies over the years and must agree with several posts. There is no one perfect stopping gun for bears but several will do the job.
IMO, ya gotta have bullets heavy enough and stout enough to break major skeletal structure and continue on well into the bear.
Your gun should fit you like a good bird gun and be absolutely as reliable as can be. I don't hang ammo and gadgets on my rifles and I remove the sling if I'm not in open country.
Years ago, I shot a medium grizzly with the rather new 338 WM with the wrong bullets but some of the few available. Thinking I had killed a grizzly, I approached the site in the willows and had a hell of time killing the wounded bear with five more shots. We won't go into the first shot as you'll tell me it's bullshit.
Another medium grizzly was hit by my partner with 338WM and it did a few gymnastics before charging straight for us. Waiting for my partner to kill him, I noticed he was trying to pickup his ammo off the ground as his floor plate had dumped. I shot with my 375H&H 300gr TBBC and hit the neck close to an ear. The bullet lodged about two inches off the side of the tail.
A large boar harassed our fish camp but on his second visit he couldn't be deterred and came at me. At 13 paces I shot him in the chest and he swapped ends and went down . His back legs were paralyzed so the 12 ga Brenneke must have penetrated considerably before impacting the spine.
For bears taken while hunting, we are naturally carrying rifles. For fish camp or canoe trips we take one 870 slug gun as everyone knows how to use it and it handles like a decent bird gun.
