Need help with first reloads.

I'm almost complete setting up my new Dillon XL650 but have a few questions.  I'll be loading .45 acp.  First, the Dillon manual states that there are different seating stems used inside the seating die depending on the bullet type; round nose, semi-wadcutter, etc.  I didn't notice any markings on the stem after disassembling the die.  How can you tell the difference?  Secondly, I purchased a small amount of the 200 gr. round nose and 185 gr. semi-wadcutter bullets to get started.  Both are copper plated.  I would like to use Unique powder at first because it apparently is a little safer to use.  However, I can't find any load info. for this combination.  I have a Lyman Reloading Handbook but it doesn't seem to be specific about what I'm trying to do.  Any suggestions?

Beeser,

It might be easier if you call me.  608-445-6816  I have answers for those questions.

Rob,
Enjoyed the conversation and appreciate the help.  I'll let everyone know how the first reloads work out.
