Hey Charlie,
Where do you get your powder in SE WI.? In Central WI I had no luck finding powder so I ended up ordering a case from powder inc.

Jay's in Menomonee Falls (I live in Milwaukee) generally has some (might call ahead); Gander Mountain is scared of the stuff, but they carry Pyrodex (cheaper than Jay's) and maybe Clean Shot (now American Pioneer Powder). You might also try that outfit in Lomira, the name escapes me at the moment, but it's BIG, and visible to the West of Highway US45, in a big metal barn-type building. Looks like you could store aircraft in there.
There are a couple of gunshops on the south side, but I don't know if they carry BP or not...one of them at least sells BP guns. You might check the Waukesha directory, and maybe the West Bend directory, too. Oshkosh PROBABLY has someplace, check with <<http://www.bradleycompanyofthefox.com>>...they're a rendezvous store, but they probably know who might sell it. Also, more on your area, <<http://www.tdcmfg.com>>...this is Tedd Cash, who makes all kinds of brass, copper, iron, and german silver accessories and inlays and stuff for BP guns...he's in Waunakee, I think.
Try going to local Rendezvoux, etc. There might be people there who can tell you about retailers.
