THERE has been a reported shooting every two weeks in Launceston since March 30.
A ensemble of usual suspects are behind most but not all of them, police say.
Detectives have made several arrests but remain frustrated by silence and an unwillingness to co-operate with authorities.
Police said the people involved were all known to them.
According to statistics provided by Tasmania Police, eight reported shootings occurred in Northern Tasmania in 2012-13 compared with just two in 2011-12.
Six of the shootings occurred in one month in Launceston.
Most are part of a running feud police said was possibly linked to drugs.
Tensions between the two groups surfaced in May.
Two targeted shootings on the morning of May 7 appear to have started things off in earnest.
The first shots were fired in Kay Street, Kings Meadows.
This was quickly followed by a second shooting in Willow Lane at Prospect Vale.
Three days later somebody fired two shots into a home on Viewbank Road, Newnham. Two women were home at the time but nobody was injured.
Police believe the shots were fired by a person or persons on foot who then made off in a getaway car.
On May 15, two gunmen walked into a housing estate in Ravenwood's Warring Street and sprayed bullets through a bedroom window.
The shooting was described as "disturbing" by Launceston Detective Senior Sergeant Johnathan Higgins not least because the woman had been wrongly targeted.
He said the woman was lucky not to be standing by the window at the time.
A man has been charged in relation to the incident but police do not allege he fired a weapon.
Shortly after this local police stepped up their efforts to put a stop to the gun crime as community concern increased.
This included increased search and seizure of firearms, more uniform patrols and the introduction of CCTV cameras at Ravenswood, police said.
On May 28 the violence escalated when a man was shot in the knee at a home in Rocherlea.
In what police believe was a retaliation shooting, two men were shot at as they walked along York Street in the Launceston CBD on July 29.
The targets escaped injury, however, a stray bullet allegedly struck a teenager in the leg standing about 80 metres away with friends.
The man underwent surgery to have the bullet removed.
A 22-year-old Newnham man has pleaded not guilty to wounding over the incident.
Then last weekend a quiet suburban street in Mowbray became the scene of another drive-by shooting.
Police said the shooting occurred about 11pm on Saturday with witnesses reporting a dark coloured four- wheel drive or ute speeding away after several shots were fired.
Police found two shotgun cartridges in the street, and minor damage was caused to the home and carport. There were three adults and a 10-year-old in the house.
In what police say is an unrelated shooting, but possibly linked to drugs, a Ravenswood home was fired upon this week.
The third shooting in less than three weeks happened in Tonga Place, Ravenswood, about 11.45pm on Wednesday. The occupant was home but was not injured when somebody fired a 12 gauge shotgun into his bedroom window.
In another shooting not connected to the feud, a man was shot in the lower back on March 30 as he was walking at Invermay.
Detectives were shocked by the senselessness of the act, which left the innocent bystander permanently disabled.
Shots were also fired in an alleged domestic situation in Binney Street, Ravenswood, in May. A 24-year-old Ravenswood man has pleaded not guilty to related charges.
Launceston CIB has said it is throwing all available resources at getting those responsible off the streets.
"We are working with businesses and the community to implement a number of pro-active strategies to reduce these crimes," Assistant Commissioner of Tasmania Police Donna Adams said this month.
