Crimped Primer Pockets - Ream or Swage

[mattiooo]

I found that some of the .223 ammo I bought had crimped primer pockets. I don't do any significant volume at the moment. Starting loading for a bolt gun. I do have an AR and may load for that as well, eventually.

I was researching options. I can't use the die ones, since my press is a Dillon 550B. So I can get one of the stand-alone swagers, or I can use the small and large reamer that came with my Lyman case prep center.

What I'm not clear on is the pros/cons on swaging versus reaming. Can anyone educate me?
