Sizing die information

I recently cast up some some 410gr .410" bullets in my new Lyman mould, decided to run them through my Lee .410" sizing die to insure they were perfectly round as quite often bullets can come out of the mould slightly imperfect.
Turns out I have two Lee .410" sizing dies, one is marked Lee-410-B6, the other is marked Lee-410-A4, my question is just what is the difference between the two.
Mike.

So far I have only used the sizer marked 410-B6, my bullets come out of the mould at .410 dia and I  just run them through the die in the interests of obtaining uniformity bullet to bullet to remove any high spots if any.  Whether this makes much of a difference to results on the target I don't know, but it costs nothing to do and may help accuracy.
