Has anyone had problems seating bullets, esp longer ones in 300BLK? About 6 out of 20 have folded at the shoulders like below. This was loading 220gr jword bullets (haven't decided on the mold yet to make proper boolits). It hasn't happened on the 150s so far. Using Hornady dies set to barely kiss it for a crimp. It occurs on both once fired 300BLK brass and on converted 5.56 brass. Am I missing something? If I were pushing for a lot of crimp, I could see it. I'll have a Lee factory crimp die in my grubby paws tomorrow, so I can see how that goes in comparison. Thanks for any insight.
