A good way to use up those .32 Maxi's would be to melt them down and pour some round ball out of them. You would probably increase the number of shots from that exercise by about 1 1/2 times.
It is said that a poacher's favorite gun is a .22. But those are typically eye shots. If you feel "eye competent", I guess the .32 would work.
But in actuality, the .32 is more of a squirrel gun than a deer gun. Besides, it probably is not legal anywhere for deer.
