Bullet is likely too hard. If the gun is tight and in good shape, speed up the bullet in steps and see if that makes a difference in leading and accuracy. Shoot from a good rest at 25 yds.; closer will only tell you that most any load shoots good up close.
If things don't improve, try a couple of other powders. Unique, Bullseye, and 231 are good to start with, but there are others.
I've never loaded for an S&W .32-20, but with many of these old guns, proper bullet diameter may be all over the place, from .311"-.314". I tried several diameters in an old Colt Army Special revolver as well as a Winchester rifle.
Back to bullet hardness... I assume you're using commercial bullets. Try to find as soft a bullet as possible and maybe some different diameters if you have no luck with the increased charges and different powders. This will probably require some experimentation to get where you want to be, but it will be worth the trouble.
If the bullet you are using requires a little effort to push through the cylinder throats, the diameter is okay. If it falls through, it's too small. Good luck-
