Trade here
I've traded a couple times with people on this board. When at the range, I pick up everything, clean & sort it all and trade when I have good quantity of good brass I'm not using. I usually use the USPS flat rate boxes. So far all has gone well. At the moment I'm out of stock, but that situation won't last long. I de-prime and fully clean & head stamp sort my brass - but that isn't typical. Set expectations. Many will send you dirty range brass. Very few will sort anything except by caliber. I won't trade anything I wouldn't reload myself which means I've inspected, cleared & cleaned anything I ship. Again - that's not typical.
