32.20 revolver loads

[ed h]

I just aquired a Police Positive Special chambered for 32.20 WCF. The old gun has some wear but appears to be sound. Does anyone have load data for revolvers? I have found some rifle loads for 32.20 but can't find any handgun data.
Thanks,

From the Lyman #48 manual...

115 cast lead bullets

W231 3.1 - 3.8 (best powder); 900 fps

Unique 3.2 - 4.0; 835 fps

Personally, I'd stick to lead, but if you must shoot jacketed...

86 gr JHP

W231 3.2 - 4.7; 1022 fps

Unique 4.1 - 4.8; 967 fps

90 gr JHP

W231 3.4 - 4.5; 937 fps

Unique 3.6 - 4.8; 865 fps

With both jacketed bullets, the max load of Unique was rated best, while 231 worked best with cast. You could split the difference and use 3.5 of W231 with any of them.

Those loads are for Colt or S&W revolvers in good condition, btw.
