You are certainly giving your buddy good advice if you suggest he uses the Nosler Partition or Barnes TSX. Both are outstanding bullets and will work well on a bear.
He needs to get some of each and see what his rifle prefers. I have been working up loads for a bunch of rifles with the Barnes TSX this year and have sure seen mixed results in regard to accuracy. Some rifles shoot them quite well with little load development while others will frustrate the hell out of you before you can get them to shoot.
