I have a nice reloading setup for my .45 ACP and want to start reloading .223 for my new 12 LRPV. Most of my equipment is Redding and I really like their dies.

;D

Loading bottleneck cartridges is new territory for me, and I'm especially stymied over the decision to get a full-length sizing die or neck sizing die. Redding has a few bushing style sets that look pretty nice, but I am still stumped. One of their neck die sets also has a body die. So....if you have to size the neck AND the body, isn't that the same as full-length sizing?

This will be the only gun that shoots these rounds, and I was under the impression that I would only need to neck size? If that's the case (no pun intended) then why does Redding include a body die in their neck sizing set?

???

I'm sure the answer will make sense when its explained to me, but just looking at their product literature doesn't provide any answers.
