Griz?
With their 2.5 to 3.0 inch forehead?

Find some pictures of their skulls the bone is no where that thick. Most good designed bullets at above 800fps well penetrate around 18 inch's. I am not talking about JHPs designed for Max stopping power on two legged targets.

Good heavier for caliber hard cast hunting bullets well easly have 30 inches of penetration. I have seen 315gr 44 cal hard cast blow right through hundreds of pound of hog, a black bear shot in the front chest bullet going out the rear quarter 40 plus inches of penetration

Shooting through a bears skull isn't that hard.

Did you just make that up?
