Hi, I've got a dillon 550 on the way, and I 've got an opportunity to complete my order for some primers (they called me on my backorder, I'm assuming I'll have to pay more for the primers than when I ordered them). I was wondering if anyone had used the small pistol wolf primers with the Dillon priming system. I've heard some of those machines can be finicky about what brand of primers. Just let me know. Thanks.
