My guess is they must have had 'em backordered about forever and are at the front of the line?
The "usual sources" I use online, and local shops, are still dry... so this looks like a windfall. Kinda like my client who works for a water district said the other night: "Just cuz we got six inches of rain in one week this year doesn't mean the drought's over!"
Hope primers DO start to flow thru the all the pipelines... soon!
I'm still waiting for primers to come in so I can get going with my first batch of handloads. I've had the press for about 3-4 weeks, all my brass is sized, inspected, and measured. I just need some primers!
