I don't think any of them ever fed the last two primers. Maybe I just got a bad one this time, I don't know. Like I said, I have loaded honestly tens of thousands of rounds using my old ones but I cannot get the new ones to work well at all. Out of every 5 attempts I end up with one that feeds, two times that doesn't dispense a primer and a couple on the floor. I've tried everything I can think of and it's just a no go.
