IMHO,,,,I would not consider the 5" .44 mag for ranges you described. The 10.5" scoped SBH with heavy cast will get enough energy to get the job done on elk and bear but, if you are comfortable with the .454 and longer barrels I would lean that way. All things considered I would have to chose a 14" contender if that is an option. Whatever you chose, good luck and good hunting
