I have a relative who has lost two good black bears on less than 50 yard shots with his 7 Rem. mag. and 150 Ballistic tips. Neither bear was lost for good. They both just ended up staying on their feet long enough to end up on somebody elses wall. I just got a Ruger 7 mag myself and bought some 175 Federals. If I don't start loading for it before Fall I figure these will do the job well at close range or farther out.
