## Main Question or Discussion Point

I've been having a discussion with some friends at a local Airsoft club for some time now and we are unable to agree on the flight distance's of identical objects that have different masses. I'll try to explain...

If a 6mm spherical object, weighing 0.2g, was fired on a horizontal path with a muzzle velocity of 350 feet per second (we've worked that out as 1.14joules?), given normal atmospheric pressure, gravity and let's say a muzzle height of 60 inches.

And then have a second identical object fired with the same statistics but it weighs 0.25g and fired with the same energy 1.14 joules (we worked out the FPS would be 313).

Now half believe the .25g would travel further than the .2g due to the momentum how ever half believe the .2 would travel further due to the higher velocity?? Can anyone help me with working out how far that object would travel before it hits the ground (resulting bounces are of no interest) or explain which one has the greatest travel distance and why? Many thanks in advance!
