Ah, the 32/20 WCF. I own 4 of them, and between the examples their respective chambers are like Duesenberg classic cars--"No Two Are Alike!" I have about 35 years with this enigmatic cartridge, and there is a definite learning curve to achieve success with it--esp. in revolvers.
First order of business--LOSE the R-P and W-W brass ASAP, and replace it with Starline. THIS is the single-largest upgrade a reloader can make with this cartridge.
Second--LOSE the Lee dies in this caliber, and replace with true full-length sizing dies that set the shoulder back to SAAMI specs. Shoulder placement in my 4 arms is all over the place, varying almost .100". Yes, those shoulders getting blown out and sized back will cause case stretch and need for trimming, but Starline does that less than did R-P and W-W. Case life isn't long, 10-12 reloads is about as good as it gets.
Third--revolver and rifle throat dimensions vary with this caliber, mine run from .312" to .314". 32/20s like 115-120 grain bullets a whole lot more IME than they do 95-100 grain bullets.
Fourth--Slower burn-rate powders like SR-4756 and Herco do better work in 32/20 revolvers than do the Bullseye/231-speed fuels. Hotter primers do better work, too--CCI #500 or WSP at minimum, and you might try SPMs like the CCI #550 if you are getting wide variance in velocities between shots.
Lastly--If you have access to the late Ken Waters' Pet Loads from Wolfe Publishing, he has an article dealing with the weirdnesses of the 32/20 in a revolver that is worth a read. It was originally published in Handloader magazine in the early 1980s.
