It's sort of a love/hate thing. The price is great, but you cannot get them again.
I used Lapua 55 gr S538s for years in my 222s and, more recently, my 223s. Apparently, they're no longer made. I got a great price on 1000 - $199 - but like they say on TV, after they're gone, they're gone!
I also got some CCI small rifle primers. Prices seem normal. These were $60/1000.
