A Melbourne go-kart racing club has rubbished claims a stray bullet from a nearby shooting range was found on the premises.
Police have shut down the Port Melbourne range temporarily after receiving several reports of gunshots in the area just after 12.30pm on Monday.
President of the neighbouring Go Kart Club of Victoria John Wall dismissed a media report a bullet was found on its grounds.
"I have no idea where this has come from," he told AAP on Tuesday.
Mr Wall said it would be "impossible" for a bullet to enter the track via the range, as it is protected by earthen barriers several metres high.
"The trajectory of a bullet fired over the abutment would mean the projectile would probably end up on the West Gate Freeway," he said.
Mr Wall said his club had never heard of a bullet straying from the adjacent range.
"Apart from the sounds of distance gunfire from heavy calibre weapons occasionally, we (don't) hear much at all from the gun club," he said.
"The Go Kart Club of Victoria has had an excellent relationship with the gun club for many, many years now and we cooperate with them regularly."
No one was injured in the incident and police are investigating.
