I've gone through 3,500 and 80% of them I loaded on my Dillon. They've been working fine. I did have teething problems.
When I first tried them I thought they were junk. I got 40% misfires. Like you, I thought they weren't fully seated. I used a Lee Ram Prime to seat them and they worked.
But then I tested them from the Dillon in other guns and it was just one gun that would misfire, even though with my usual Winchester SPP that gun fired fine. But the strain screw was backed out a bit. A little tightening made them go off.
So they might be a little "hard". But I'm good with them now.
