April 2013 issue of The Handloader has a good article about bear hunting with a Ruger Blackhawk in 45 Colt. Black bear (cinnamon colored) was DRT at first shot, but kid emptied the revolver into him anyway. Penetration and wounds were impressive. The loading table has loads to 23,000 PSI, OK for a new N Frame S&W. I may try them in my Mountain Gun.
