Bought a new Ballisti Cast Mark II and have only used it three times. The valves constantly leak and I'm stuggling to have a successful casting session. Only used virgin (clean) 92-6-2 lead in the machine so it is very clean. When I first used the machine it leaked from the first day. Once running the leak would subside a little and it was possible to cast good bullets. Then at no particular interval it would begin leaking quite badly and cover rotating moulds. Asking the manufacturer I was told to rotate the valves in the orifices with an allen head tool to a different position in the orifices but this rarely rectified the problem.
The leak begins as soon as the lead melts to approximately 550 degrees F or when it virtually liquefies. On occasion one valve will leak, then both then sometimes the other one only. Very frustrating. The machine works well otherwise although I'm new to casting and need to get some experience time up with lead temps, mould temps and pour durations. This is proving elusive while the leaking valve issue persists.
