32 WCF, is 32 Winchester Center Fire or 32-20. Be careful about the ammunition you fire through these old timers original factory stuff cleared the barrel with only 20 grains of black powder. Winchester Western and Remington still manufacture ammo, best prices are from "Cheaper than Dirt". That stuff is moving around 1200fps and is a 100grn lead bullet, that should be considered the maximum and only in a pistol with a clean bore. I haven't reloaded for my newly aquired 4th model but plan on using 115grn SWC and starting out around 1000fps, there are also jacketed hollow points available from Hornady in 85 and 100grn. An 85grn JHP at 1000fps would also be a good start at least from my perspective.
