I have 5 guns chambered in 32WCF 2 Colts, a Winchester 73, a Marlin and a S&W Hand ejector.
Two of the 5 were made prior to the smokeless era, the 73 and a Colt...
These required me to reload in BP.
Added to the fact 32 WCF is seldom seen, even among the CAS shooters. reloading is my only real option.
I bought Starline brass, I don't recall the price, I think it was $32 a hundred count.
but Bullet Barn has it in stock The Bullet Barn - Unprimed Brass
as does Reloading Brass Shop
Starline Brass 32-20 WCF For Sale | Reloading Brass Store (reloadingbrassusa.com)
I have not purchased lately but it looks like $42 a hundred is ballpark.
