Why not load the 225 Gr bullets . Think they are better suited in the 358 and would do a lot better on the bears . they are a bit flatter shooting and carry enough engery for the bears . Serria and Accubonds are the hammers . I would use the rounds on deer through and including moose . Then also your going to learn where the "one" round is hitting at what range, with that gun, with some practice .
Nothin' builds more confidence- than working the range with one load, one rifle, and seeing one dead animal after the other, always knowing where that bullet is going to hit.
It stops the brain from working on what range ,with What bullet have I got ? thing- before taking the shot . Instead you will smile since "I got ya!"
Always works for me >
Happy
