If not going to reload them again I'd use the cutter.
This is just crazy.
I've reloaded a bunch of military 5.56 and .308 brass, and use a crimp reamer exclusively. They are just as fast as a Dillon, considerably cheaper, and require no setup or adjustment when using different head stamps. I set mine up in an RCBS trim center, and alternate the reamer with a primer pocket uniforming tool...never had an issue.
eta: I've done thousands upon thousands this way, and will never go back to swaging.
