British military training with live ammo in country parks?
Those of us who metal detect will of course be familiar with the blank rounds which litter the countryside from British army training in the 80s. However, recently I have found fired bullets (not casings) around various spots in Hong Kong, near or on major hiking routes like the MacLehose trail, sometimes smack dab in the center of the path where hundreds of thousands of hikers have likely trodden.
