Yes, same velocity they went up with

Nope. As soon as it leaves the barrel it's slowing down, as, AFAIK,
bullets are supersonic, and I know of nothing that has a terminal speed
greater than the speed of sound, at least at this size! After it reaches
the apex, where its vertical speed is zero, it is now speeding up, and
will slowly (exponential decay style) approach terminal speed. Donno what
number that is, though.
