Long Range - 210 yards with Kalibr Cricket .25

[Dagwood]

Think the vid is in slow motion. They don't take that long to reach even those distances.
At 210 yard, if say the pellets were dropping approx 32 feet, that would mean the time taken for the pellet to reach the target
from leaving the barrel would be about 1 second as the speed of gravity is about 32 feet per second.

The video subtitles do state that slow motion is being used.
How has gravity got anything to do with the time it takes a pellet to travel 210yards? Surely it is the power of the rifle and the pellet used which affect the speed of the pellet to traverse the 210yards that are the relevant factors? If I look at Chairgun and plug in 12fpe using a .177 Bisley Long Range Gold pellet it takes 1.6 seconds to traverse 210yards on a level playing field. Where does the rate with which gravity affects a pellet come into that?
