On Wednesday, the Supreme Court jury also heard a series of loud bangs in quick succession from further CCTV footage, the only clip with sound, recorded inside games shop Guf - also known as Good Games - looking out to York Street.

The Crown says passenger Sean Gregory Richardson, 25, fired seven shots across the car roof - all missing their two intended targets - as revenge for the earlier shooting in the leg of driver Damien Wesley Marshall, 31, in Lilydale Road.

Mr Richardson and Mr Marshall pleaded not guilty on Tuesday to two counts of aggravated assault against Robert Williams and Paul Axton, and not guilty to wounding stranger Isaak Heathcote, then 19, on July 29, 2013, about 10.15pm.

Crown prosecutor John Ransom called complainant Mr Heathcote, now 21, to give evidence and he said he had been sitting outside Guf in York Street with his friends. "I heard five to six loud bangs ... it felt like someone had hit me in the leg," he said. Mr Heathcote said he initially believed he had been struck with a rock or firecracker, but felt "excruciating pain" in his leg and was taken to hospital by ambulance. "There was blood coming out of it," he said of his wound.

Mr Heathcote described the "loud bangs" being two to three times as loud as a person clapping.

Earlier, medical administration registrar Zachary Scollard gave evidence for the Crown about Mr Heathcote's admission to the Launceston General Hospital emergency department on July 29, 2013, at 10.50pm.

Dr Scollard said Mr Heathcote had surgery to remove a metallic foreign body embedded in the lower part of his right leg, suspected to be a bullet.

Jurors also watched a compilation of CCTV footage, which the Crown argues shows the movements of the co-accused men and their use of a distinctive green Commodore before, during and after the Launceston shooting.

The trial, before Justice Helen Wood, continues.
