If the subject brass is .38 Special then by all means, your best avenue for value is to find someone selling used brass.
.38 Special may very well be the most durable, long lasting, load-the-stuff-until-you-die brass there ever was. It doesn't get lost, because it doesn't get flung from an auto-chucker. And the loads are not hot & heavy, they run a mild pressure and don't need a gorilla crimp on them.
.38 Special brass doesn't wear out easily. Buy some used range brass or "once fired" or whatever they call it... it's your best deal by far.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
