“Once they exit the barrel, bullets immediately start slowing down as gravity begins to exert an influence.”
Umm, gravity is NOT what slows the bullet down. It is aerodynamic drag that slows it down. At two hundred yards, the bullet will drop about 2 inches from the barrel elevation.
This would work. If captured the Taliban would have to figure out how it works as the sniper would be dead. Issue fewer bullets. They won’t need them.

If fired level. Scoped rifles aim bullets “above” the bore line. A rifle zeroed at 200 wards and fired level will have the bullet rising out to 100 yards or so, and dropping onto target.
Above line of sight. rather. It uoh know these things.
My understanding is that the time it takes for a bullet dropped from the height of the barrel, to hit the ground, is the time the bullet, fired from a level barrel, has to travel. The speed the bullet has no influence upon how long the bullet is in the air, just how far the bullet travels.
