i realize that i can kill ducks with smaller rounds then 3 1/2s but i only use those for those big norther canada's. I usualy shoot 3 inch 4 at ducks so i am not really throwing magnums out there all the time. i also have some shoulder problemsthat on a heavy shooting day reallymakes it flare up. i would just like something that takes some recoil out and i have always wanted an auto loader anyway.
