I'm shooting the Barnes 225gr TSX bullets out of the 35 Whelen, it crushes black bear. I can only imagine what that bullet would be like out of the .358 Norma mag!!! I'll be trying the Hammer 223gr Shock Hammers this year out of the Whelen. I had a .358 Norma mag, one of the most accurate rifles I ever owned. I've even tried to track that rifle down, however have not had any luck finding it. The rifle was built by an old time barrel maker who worked at a local shot called Johnson Automatics in Wyoming, Rhode Island. Good luck with your new rifle. Post some photos when you get the rifle.
