you're comparing a maybe 100 pound pig to a 700 pound grizzly. slugs over buckshot every day. There was a group of duck hunters up here who killed a bear that attacked them while hunting. think they shot it 7 or 8 times at point blank range before it was done movingI have zero experience in grizzly country, but my experience with TSS “buckshot” loads using BB size shot has convinced me that they are one of the best options for stopping an animal at close range.
I can get 49 pellets in a 20 gauge hull. Any one of those will pass all the way through both femurs and the pelvis, or through both shoulder blades and spine, on a full grown pig. The pattern is tight enough that I doubt a bear skull would slip through a shot unscathed at 50 yards. At 25 yards nearly the whole pattern is inside a 2’x2’ square.
A semi auto 12 gauge loaded with BB, T, or #4 buck size TSS in a 3” shell would absolutely blanket a charging bear in pellets
