All reloadable brass is worth money!
Store it and after you get an ammount (100 or so) advertise it for sale on here!
I really don't know what it is now, but it used to be figured that about 60% of the retail price paid for loaded (factory) ammo was for the brass itself and the other 40% was for the primer, powder and bullet!
Check in a Cabela's, Midsouth, Midway or other supply catalog to see what brass goes for these days!
