John,
I think you are right, but I haven't got one. With the shitty gun laws we have I cannot afford to waste a licence. I'm busy building a 416 Rigby.

One of the guys in the air rifle club shot a jackal with a high powered PCP and killed it. I will certainly never even think of trying to kill an jackal with a air rifle. It is like hunting a ele with a .22Lr. It can be done, but it is not the right thing to do.
