Many shooters reload their cartridge cases, but others merely collect it 
for sale.

There is a class of cartridge cases with a primer type that is unusual 
in the USA, called a Berdan primer.  These are typically considered 
non-reloadable on this side of the Pond. Often, you can obtain large 
quantities of Berdan-primed cartridge cases for next to nothing.

I can post WTB or ISO messages on reloading forums if enough people want 
cases.  Please PM me offline if you're interested.
