Hartcreek, that is exactly what I was saying, my roll crimps looked like that many years ago when I had first started reloading, and then I learned how to crimp.
But this type of issue was caused by crimping to far above the bottom of the canelure, increase the oal, adjust your crimp, and try again. And considering the OP didn't deform the bullet, when you are crimping in the right spot, you can indeed deform a bullet with too much crimp, plated, jacketed, or other wise.
