Dave,
Powder selection for the .32 Spcl is identical to best powders for the .30-30. And yes, excellent 2000 fps accuracy can be expected from properly sized, gas-checked bullets. For your Marlin, using cast bullets will necessitate using .323" bullets for best accuracy and freedom from leading.
Best powders will probably prove to be H335, RL-7 and 3031. Too, try using a Lee Factory Crimp die.... it will dramatically improve group sizes in most instances with this cartridge.
The reputation of .32 Spcl. rifles losing accuracy when compared to .30-30's as they wear, is that the .32 Spcl was designed as a cartridge that could be reloaded using Black Powder.... way back when in was introduced, and as such the .32 Spcl has a 1-16" twist which was thought to better handle black powder fouling should the round be reloaded using black. In any case, when the rifling begins to wear, especially on the Marlin rifles which had somewhat oversize bores to begin with, usually accuracy does suffer when shooting traditional .321" jacketed bullets.
Hopefully this info will help you.
God Bless,
Marshall
