Its probably more than you need most of the the time, but yesterday I spotted a bedded bear about 100 yards away, and went to get my buddy who was carrying a .308 150gr. After waiting about a 1/2 hr the bear stood up and gave him a shot. There were a couple small twigs that we could see, but possibly more that we couldn't. He had a steady rest at a sanding bear and never touched him. Could have been bear fever, as it was only his second time bear hunting, and the first bear he's ever seen in the woods, but I was thinking if I was shooting my .338 250gr the twigs wouldn't have been a concern. 250gr is even more overkill, but my cousin took his .338 w/250gr on a Alaskan moose hunt, so we figured we use the same ammo. Also, if you ever plan to go for larger game/ out west, the .338 shoots just as flat as a .300, but with more energy.
