Thruxton is absolutely right in all he says about England. There is no such thing as public land to shoot over.
Driven Pheasant shooting this season is likely to cost about £50 or $80 PER BIRD and a normal bag size would be 200 birds, divided between eight Guns. Many game shooters like for shooting to remain expensive and therefore exclusive. A certain amount is funded by companies with deep pockets as corporate entertainment.
In France the laws are different and most villages have a shooting association run as a cooperative. There are some private fenced estates as well especially in the Sologne south of Paris. Germany is different again; others will know more about that than I.
