I've got a buddy who does a brass business and has contracts with a number of local ranges and also buys large lots of cartridge brass (usually in a 55-gal drum) and he separates all the small primer .45 out and doesn't sell any of it.
Part of it is supplying what people want and ensuring there is no small primer crap in there. The other part of it is that he's hoarding it until the day comes when all of those thoughtless makers start producing it in small primer exclusively. By that time, he'll have a major stash of it. Until the day comes when it's what everyone wants, he'll simply stockpile it.
I predict it will take 106 years before the lion's share of us agree with the mere existence of the stuff.
Willy, great to have ya back around!
