What is causing this and how do I fix it?
I'm using a Dillon 550. Seating die in station 3 only seats the bullet. I have a Lee Factory Crimp die in station 4. Everything is perfect until the 4th station where I feel the case buckle. I reseated the crimp die. I put a good round in there, raise a dummy round and screw in the die until it makes contact. Lower the dummy round and turn in 1/4 of a turn. I raise it up, no issue; very slight crimp but not enough to hold the bullet well (I'm able to push hard and lower the bullet). I screw in the crimp die 1/8 of a turn; and what you see below is what I get. I've tried several cases including new never fired cases.
I must have loaded several thousand rounds of 223 by now and this is the first I've seen this. I did not make any drastic changes. In fact, prior to this, I was had loaded about 20 perfect rounds.
