You will need a crimp removal tool of some kind. Because even if you don't buy ammo with crimps, sooner or later you're going to find a big pile of crimped brass... and you just don't walk away from free brass.
The dillon super swager is really popular, but I never liked it. I sold mine. The hornady hand tool is what I use. It's like $20 at midwayusa.com, and the bit can be chucked in a drill for large batches.
