My dealer just got in an order of 100,000 Federal Small Pistol Primers that he ordered last January. His distributor told him they're working through the orders and shipping what they can get, in the order they were placed. They're one year behind on orders, just because they weren't able to get the product.
All the primers in this order were pre-sold, and he has another order in for 200,000 SP primers that he placed last February. He did receive 100,000 Small Rifle primers a month ago, and those were also pre-sold. At least they're starting to show up.
Hope this helps.
Fred
