Thanks everyone. I'm going to tinker with this and share what I find.
Off the top:
- I'm using hornady custom die set. It doesn't say what type of crimp, but it does not look like rolled crimp to me. I will likely get the lee factory crimper later.
- I'm very certain the slight bulge is because of the bullet. Seems to match the length of the bullet. Seems tight enough so the bullet doesn't press in by hand.
I will take a few more measurements, compare o factory round I.e. clambering in a safe barrel, try to increase and decrease the crimp to see how things change, try a few different headstamps...
