The issue is there are bears and then there are bears if you know what it mean. I've shot lot's of 150-250lbs bears and that load should work great. The. There are a couple of 500-600 lbs boars I've shot that I would not want to use that load on. 160 Nosler Partitions would probably be minimum on those.

I've shot most of my bears raiding my uncles corn field in early September and the shots are usually under 20 yards and as close as 7 yards. The big lads are almost a deifernt species, smarter, way tougher and they don't fear much. The little sub 250lbs bears are terrified of the big boys and they tend to run like rabbits at th first sound/smell of danger. 12g SxS with slugs or the big 10g with 3.5 inch OOO work pretty well. 35 Whelen and 356 Winchester are perfect.

I would look for a heavier and tougher bullet you never know when you will run across one of the big boys.
