A 5lb cannon ball WOULD go as far as a 10lb cannon ball if they had the same initial velocity and size. The only force acting on each object on the 'x-axis' is air resistance. Both balls, being the same size, would travel the same distance given the same initial velocity (only the 10lb ball would take more energy to reach that velocity than the 5lb ball). Refer to Galileo's experiment at the leaning tower of pisa

If just4kickz is referring to a "controlled environment" as a vacuum (ie. no air), he is correct--a rock and a feather will fall at the same speed.
