1. Cut away most of the crimp with a countersink or the small blade of my pocket knife.
2. Finish up with a Lyman hand reamer, cutting away the remainder .
3. Complete the job with Lyman Primer Pocket Uniforming Tool.
Notice each step involves cutting the crimp away....the reason is when a swag tool is used the brass has some spring back and usually doesn't do a complete and proper job.
With my method every pocket will be properly sized for new primers .
50 years ago all our 30-06, 45 acp and even 38 special were military surplus , dirt cheap and crimped ....so you learned how to deal with those pesky crimps .
