Death Gatling (Infinite Ammo + Bottomless Clip) vs Black S (No merging)

Death Gatling starts at the top of the New Hero Association (where blast teleported FF and Saitama when dimension slash happened) and the Black S are all on the ground level climbing up through various means or splitting and stacking on top of eachother. (black S can no morph or grow his body, he must stay in the form that is pictured when splitting)

Does Black S get to Death Gatling before getting his cell stock wiped out?
