A rabbit-shooter in Essex had a shock when a rifle cartridge went off in his pocket.
Gareth Jones from South Norfolk was shooting rabbits at night on a golf course when the spare battery for his night vision short-circuited through a .17HMR round, and set it off. It gave him a minor burn on his stomach.
