I run 225's out of my 338wm for elk and moose(no brown bear here or hunts to in my future). Started with AB's in this rifle, shot good but didn't really like the results on a moose shot a few years ago. I switched to barnes TSX which I've had great results on the likes of the biggest deer in NA and never looked back. Groups amazing and performance is stellar as usual. I wouldn't hesitate to use a 225gr tsx on any bear...including a brown!
