Hope this is the right place for this, and I'm sure the vast majority of posters here don't need to be told, but after seeing some truly shocking idiocy on youtube I think it's worth saying:

1. Wild animals are not there for target practice.
2. Never shoot anything that's not: a recognised health hazard (e.g. rats, feral pigeons); an agricultural pest (e.g. woodies, crows); known to be excellent with red wine (e.g. rabbits, woodies ).
3. Small game only.
4. If you're not killing consistently with one shot, stop hunting and go back to target practice until you improve.
