Iowahunter,
Nice find and at a good price too! The UMC 32-20 HV cases were fired with mercuric priming, which will weaken the brass, making it brittle. If it is reloaded, there is the strong possibility that the cases might fracture, allowing gas to escape out of the action. Been there, done that.
The WRA Co 32WCF, Peters 32-20, Rem-Umc 32-20Win, Rem-Umc 32 WCF, Western 32-20 Win and Dominion 32-20 would all be suspect as well.
Depending on when they were manufactured, they may or may not have been fired with mercuric primers. Best not to take a chance.
The Super X 32-20 and WRA 32-20 would be ok.
Stay safe,
