So based on a tensile strength of 100kg with a 3kg projectile, gives an approximate 33N moment. What sort of range do you get? Back of the envelope maths with the ball being released at around 2m altitude puts it a bit over 55m.
Range with a 2 litre milk bottle was around 50 - 60m. But for the best range the bottle was releasing at a greater height than 2m - more like 4m - like a howitser, the best range is with the release at 45 degrees.

Being about 1/4 scale , this would indicate a full scale machine would throw a 120kg missile around 240m - about right according to historical records.
