I am not sure why outlawing moonflighting or other of the established and historical wildfowling practices legitimately allowed in the UK (i.e. puntgunning, use of 8 bores and larger) would necessarily make life better for other "sportsmen" given that

- most wildfowling clubs here are struggling to find members (new entrants are tough to find)
- there are probably less than half a dozen regular punt gunners in the UK in total
- moonflighting is wholly dependant on conditions; remember that there are are only 5/6 full moons in a season, most of which won't be suitable.

Most people who I have shot with have little or no experience of wildfowling, tending to shot driven game or rough shoot inland. Therefore, the impact of wildfowling on bird populations, disturbance etc generally continues to be very low level and is likely to continue to be so.
