Another use for the tight chokes on Germanic drillings and combination guns was shooting "auerhahn," or "black game," or "capercaillie" (doubtful spellings...), a HUGE forest grouse that looks a little like a turkey crossed with a blue grouse. Not sure how they are hunted, but I believe it is somewhat like turkey hunting, hence the "turkey" chokes.

Anybody know the status of hunting these in Western Europe? Extinct in places? Protected? I know (from member's pix) that they are still hunted in Eastern Europe and Scandinavia.
