my guess would be seating die is too low... or just the seater itself too low in the die.

Yeah, the end of the case is running into the crimper shoulder. The case can't crimp into a cannelure, so it buckles the shoulder of the brass. Back the seater die off a half turn, maybe even a full turn, then re-adjust the seater to where you want the bullet seated.

Yep, too much crimp. Take seating stem out completely and take the die clear out of the press. Put a case in the shell holder and take it to the top position. Now screw the die down until you feel it hit the case. Now back the die off a full turn and tighten the lock ring. This method will give you NO CRIMP.
