Yep, we've been trying to find primers for awhile. I got excited when I went to one gun store and they told me "Sure, they had primers".....one box of 100. (.223) That's it. And even if they had more, they were limiting people to 5 boxes.
DH even heard one of the salesmen at his favorite gun shop tell a customer that Dillon Press is waay behind on orders. Anyone just now planning to learn to reload isn't going to get their equipment from Dillon any time soon.
I would start with a good old RCBS Rock Chucker single-stage and learn how to reload before I got myself all tangled up with a progressive system. That's a good way to get into some serious trouble.
RCBS still makes the best single-stage press, but they don't have a clue how to make a progressive loader. That's why I covet a Big Blue.
The Rock Chuckers are still very much available - even on Amazon! :-)
