Oh, it's never really a case of NEED is it? : ) I have a marlin 95 in 45/70, and yeah, it's pretty brutal with heavy loads too.
I have been a member of a hunting lease in Texas the last few years, and the guy that is the head dog on the lease has one of the handguns in .500, thus the story I related above. I fired the handgun a couple of times, and can't for the life of me figure out why anyone would want one, but that's just me. I really would like the handi rifle though, just to say I have one if nothing else. I have a lot of firearms that I have no real NEED for. 90% of the time when I hunt somewhere out of state, I take a 30 06. Apparently I sometimes have too much time on my hands : )
