Any two markers set at the same velocity will have the same range. If at 290 fps, then in one second both balls will go 290 feet. Although the tippmann flatline puts backspin in the ball so it generates lift, but thats a different thing altogether. It depens on the spin of the ball. Foreward spin will make the ball pitch down, effectively reducing range, while backspin does the opposite. Markers all have the same range, a ball fired from an ir3 will fly no further than one from a stingray.
