The math is essentially wrong. there needs to be:

first shot damage is X

enemy health is Y

2nd shot damage will be  (((Y-X)/Y) * 2 + 1) * X

3rd shot will be  (((Y-X -  (((Y-X)/Y) * 2 + 1) * X )/Y) * 2 + 1) * X

last shot will be  (((Y- X -  (((Y-X)/Y) * 2 + 1) * X ) -  (((Y-X -  (((Y-X)/Y) * 2 + 1) * X )/Y) * 2 + 1) * X /Y) * 2 + 1) * X * (2 + bonus crit chance)

so yeah, your ult will kill if

(((Y- X -  (((Y-X)/Y) * 2 + 1) * X ) -  (((Y-X -  (((Y-X)/Y) * 2 + 1) * X )/Y) * 2 + 1) * X /Y) * 2 + 1) * X * (2 + bonus crit chance) +  (((Y-X -  (((Y-X)/Y) * 2 + 1) * X )/Y) * 2 + 1) * X +  (((Y-X)/Y) * 2 + 1) * X = Y

That means, if you hit all bullets, check if your first brings the enemy from 100% - 87%. depending on regen, he will die. if you don't have IE.
