I have an older Contender, with a .223 barrel, 6mm tcu barrel, .357 Max barrel,with a TC4pwr scope. I want to hunt deer, black bear, possibly elk. I don't know if I should get a 45/70 barrel for the Contender, as I don't know how much recoil, compared to a SRH .44 mag. Also, how good is this cartridge, at , say, 150 yards. Or should I get an Encore, with a 243 barrel. Also, what brand and power of scope? Appreciate any help. Thanks
