Editing Sling (weapon) (section)

==== "Whistling" bullets ====
Some bullets have been found with holes drilled in them. It was thought the holes were to contain poison. John Reid of the [[Trimontium (Newstead)|Trimontium]] Trust, finding holed Roman bullets excavated at the Burnswark [[Hillforts in Scotland|hillfort]], has proposed that the holes would cause the bullets to "whistle" in flight and the sound would intimidate opponents. The holed bullets were generally small and thus not particularly dangerous. Several could fit into a pouch and a single slinger could produce a terrorizing barrage. Experiments with modern copies demonstrate they produce a whooshing sound in flight.<ref>{{cite web|url=http://www.archaeology.co.uk/articles/features/burnswark.htm|website=Current Archeology|title=Bullets, ballistas, and Burnswark – A Roman assault on a hillfort in Scotland|date=1 June 2016}}</ref>
