redhawk,
Generally, the 44-40 WCF is usually found in single action. However, S&W had a special run of these in their N frame size. Nothing special to do with the loading. Most all manuals have data. Being a bottleneck type cartridge you have to take a bit more care in the reloading process. Even then, you'll loose some brass when seating the bullet. No big deal though.
If you decide not to keep it let me know. I may be interested. Can trade or whatever.
