According to my Ballistics program the flight time should be around 1.5 seconds, using BC 0.020 and muzzle velocity 280 mps (919fps). He would have to have a holdover of 20ft and the pellet would have 2.2ft-lbs when hitting the bottle.
And by the way speed of sound is 343mps(1129fps)
Im getting realy curious if it can be done though. 200m…
Doing the same calculation on a barracuda cal .25 at 1050 fps one would need a 10ft hold over and the pellet would hit with 12ft-lbs. Flight time would be 1 second and the pellet would travel 4.5ft over the sight line at its highest point.
I will have to test this
