OK, so here is a question for you 338 Fed owners. Not sure if this is the right place to ask it, but with such a big group of knowledgeable people in this thread I figured "what the heck".

I ordered both the RCBS full length die set and the separate RCBS neck sizer die, however I received the neck sizer set instead of just the neck sizer die.

So now I have two bullet seater dies (one from each set), but oddly, they are numbered differently. One of them is #14 (which came with the #14 full length sizer) and the other is #18 (which came with the #17 neck sizer).

Anyone know if there is any difference between the #14 and #18 bullet seaters ?
