There were cases of 10,000 going in the January Holts auctions
One of my shooting groups bought one of the 10k lots (they were all Fiocchi), and everyone had 1 or 2k from the batch. Unfortunately, it turned out that about 1% or so split upon firing - so some gas fouling on the bolt. Presumably thats why they were all in the auction in the first place - faulty stock.
Thus the buyer gathered them all back off everyone and sent them back to Holts for a refund.
Later on, we started hearing the bad news from the importers that there were to be no more primers for a year or even longer, and it was already dues-out at most of the suppliers.
Hence our buyer went running back to Holts to ask if we could have all the primers back again! Faulty primers are better than no primers.
