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.
