savageT,
The best source for most the more uncommon brass that was made made in this country at one time or another (.358, 32-20,etc.), but dropped for reasons unknown, is Graff & Sons, Inc. Just checked their web site and they had all the brass you listed either in Remington or Winchester.
Other companies I order from include: Midway and Cabelas. In any case, between Graff & Sons, Midway, and Cabela's you should find what you are looking for. It seems to me that Graff & Sons always has the widest selection of reloading brass --and a good supply of it.
I have good luck with both Winchester and Remington Brass in bulk from all these companies. However I only reload the '06, 338 and .458 rifle cartridge cases. Hope this helps......Balto
