I don't know how much experience you have roll crimping or what type of crimper you have.

Once fired shells rarely roll crimp well unless you can cut away the star crip or iron out the roll crimp to look new.

I use a BPI crimper and warm it up on some throw away hulls and lube it with just a smidgen/dab (yes that is a unit of measure) of anti-seize lube . Start the crimp slowly and you can feel when the crimp starts to roll then move the crimper down a little quicker.

I like to have block of loaded rounds ready so the crimper doesn't cool between rounds.

Star crimping be sure you have the correct crimp starter in (6 or 8 point) and your machine adjusted correctly. I use a regular MEC 600 16ga with a short shell kit in it. Star crimping once fired roll crimped shells rarely works well unless you ironed out the roll crimp to look new.

After the first shot the rest are just noise.
