32 Win Special Mouse Fart loads

[keyholer]

This is a request for mouse fart loads in a 24 inch .321 barrel using an 80 grain plain base round nose bullet. The bullets can be sized either .321 or .323; I'm leaning toward .323. Powders on hand are Unique and Trail Boss, but I'll welcome suggestions for any load that might shoot well from the 32 Winchester Special without leading.

Follow the instructions for finding the load for trail boss.

It is a good powder for what you want to do and it had been shooting good in my rifles.

323 will be fine.
use a load for the 30-30 if necessary.
unique will be in the 6-7 gr range, and may benefit from a tick of Dacron to avoid vertical stringing.
I'd be inclined to try something like 4-5 grs of red-dot, clays, titegroup, 231, or bulls eye too.
