The rifle you are speaking of is only popular with a small number of airgunners in the US due to the extreme noise and power they produce.
The gun itself is on a blurred line between airguns and firearms, personally (dont take this the wrong way) I'd buy a rimfire instead, the ammo will be cheaper, the guns are equally as noisy, equaly powerful and you would need to buy lots of air, I doubt it gets more than 5 shots a fill before re-filling.
In many places it would be illegal to use for hunting, there are no shooting sports that allow that kind of power (at least in an airgun). So you are left with target shooting......5 shots a fill aint too handy with a PCP.
This is just my take of course, there are some big-bore airgun hunters that love these rifles, but you just need to find a place that allows it.
