I bought this as a Lee Collet Rem 223 die set a while back and have never used it. It was sold to me as a used full case sizing set, but I now understand that Collet is neck sizing only. Now the confusing part. This is my first rifle die set. From what I have found online, Lee Collet sets only have two dies. Can any of you experiencedreloaders tell me what I have and which each of these dies do? I have only reloaded 38 special, 44 special and 44 mag to this point.
