I reload for a buddy with 210gr TSX FB and watched him punch three of them lengthwise through the biggest Kodiak bear I have ever been around. The first shot was broadside and it hit plenty of bone and left like the three end-on bullets.
He also shoots a big bull moose every year and usually a caribou, too with the same bullet. He likes it a lot.
I have yet to see any Accubond go through a brown bear. Every one has been caught, 338, 358, and 375 calibers... Not a lot of them, but enough to know it would not come close to making my list.
