Dont know of any shops that buy brass, but it would probably sell on the EE here.
Reloading is as crazy priced as loaded ammo right now.... I saw primers for $12 per 100pk in a shop yesterday and $90 per 1K !!! I have still been buying powder and bullets reasonable but the primers are few and far between at a good cost factor.
I am going to load up the last few thousand rounds that I have components for and then wait and see, after that I will hit the ammo cache that has been built up for 15-20 years.... after that?
List the brass reasonably here in the classifieds and they will sell....
