I use these in this order more or less...
Ruger 77-Hornet (50g Sierra SP at around 2500 fps)
Open sighted Marlin 1894C 357 magnum (125g SP at around 1400 fps)
870 20 gauge express magnum youth version fitted with adult stock (Federal 3" magnum #2 shot, or Win. supreme 3" #4 shot)
I've also hunted predators with my 357 Blackhawk, but my 32 magnum Single-Six is gonna likely replace it on future hunts
