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?

We were working out the time the pellet was in the air from the reported pellet drop i.e. Time = the square root of twice the distance of fall over g .

Fall reported as 32 feet. Therefore: twice 34 =64 divided by g (32ft/sec/sec) = 2 -> square root of 2 = 1.41seconds flight time - simples!

The error of course is the pellet was not fired at 0 degrees elevation... However given we did not know the power of the rifle a reasonable estimate.
