No. They don't need to be terribly accurate. This is just to make the
non press fit end of alignment pins a little faster to start. They do
need to be pretty and smooth though.

I don't see a good reason to round the ends for that purpose. A
chamfered or conical end would be easier to cut with good finish
than a hemisphere, and probably better as an insertion aid.
