I'd stick with the .357. I've found mine quite useful for everything from squirrels and rabbits to woodchucks and deer. My old Marlin 1894C was accurate enough that I could kill woodchucks regularly out to 150 yards and 200 wasn't uncommon. It worked very well on several deer inside 100 yards and I killed one at just over 200 with it. All were one shot kills and even the 200 yarder was a passthrough with 158 gr. soft point. I'd like to know why anybody would say the Williams receiver sights are a joke as I've killed more game with mine than you could fit in a boxcar over the past 40 odd years and have yet to have a problem with them.
