I've gotten Brass from Brassman in the past. Been happy with it. As others have said, scrounging can get you there, if you have patience. If you are in a hurry, buy a batch. It will grow after that.
Same here at the range people are happy to give em to youSeveral have PM'd me on the brass. I have not been well enough to dig through it lately. Getting set up for my new chemo journey. Only one trip to the range in three weeks, so ...
But I wanted to say, on some of the "i own it" comments - my range costs much less per day than any other in the area cost per hour, and the right to pick up your own, if you request that when you arrive, and no crossing the firing line (range is never cold) all contribute to the policies. The brass recycling contributes to reducing the operating costs. Since I read the policies, and follow them, I'm agreeable to it. I've seen the arguments between RO and some reloaders (who get to leave) who demand the range be called cold so they can recover some special bit of brass, after they've read the rules.
