I’ve got several thousand rounds of once fired, decapped and tumbled 9mm brass. A friend of mine wants to trade me some large rifle magnum primers (that I dearly need) but I don’t know what the “exchange” rate should be. I’m seeing processed 9mm brass from $42 per thousand up to $129 per thousand. I dont want to rip him off but I don’t want to have wasted my time processing either. What do y’all think is fair?
