I've been debating various Sci-Fi vs debates for a while now and I've decided to try and figure out how powerful the C-14 Gauss assault rifle from StarCraft needs to be in order to achieve the following feat:
A league is 5.556km, so halfway up a 20 league vortex would be 55.56km from the ground.
The standard issue C-14 Gauss rifle fires 8mm DU spikes with a fairly aerodynamic shape (narrow rounded tip and slightly rounded rear) that is either 5cm or 6.4cm long. It is neosteel tipped so I'd assume that's how it avoids getting vaporized by the friction, neosteel being a super hard future alloy. The projectile mass should be somewhere between 43 and 66 grams.
Assuming earthlike gravity and atmospheric pressure (it is an inhabited planet), ignoring the winds from the vortex and assuming the Marines were firing at a perfect 90 degrees angle, what would be the minimal muzzle velocity of a C-14 spike to reach 55.56km straight up?
"a complex mass of conflicting pressure systems and staggering
updrafts that have created what is, in simple terms, a stationary,
volatile vortex of immense size and unlimited life. It is four leagues
wide and over twenty high."

out of this predicament when suddenly the whole environment
darkened.
There wasn’t much light inside the funnel anyway,
but when the Wraith fighter and four dropships
appeared at the funnel’s top, it had the effect of eclipsing
what little light there was. Somo peered up and watched
the craft descend. Once they reached the funnel’s
halfway point, the turret came to life. The Wraith positioned
itself to take the entirety of the barrage of automatic
missile fire. Bright coronas erupted around the
fighter as several missiles struck the outer shields. There
were smaller impacts as well, and Somo realized that the
marines must have begun firing at the fighter . . . but at
least that meant the marines were distracted.
