Beven John Gleeson appeared in the Launceston Supreme Court on Monday for trial, but he changed his plea before a jury was empanelled.

Chief Justice Alan Blow told potential jurors the late change was because the state government was upgrading the Launceston Remand Centre which meant lawyers were unable to see their clients on weekends.

Gleeson, of Mayfield, lived at his dad's house on Herbert Street at the time of the shooting.

The court heard there were ongoing issues with Jake Talbot, whose mum and stepfather lived around the corner on Mayfield Street.

Talbot went to his mum's house with three friends after hearing Gleeson wanted to fight.

After parking outside his mum's house, Talbot yelled: "Bevo, where are you Bevo".

Gleeson, 30, walked down the street armed with the shotgun and said: "C'mon you dogs".

The four men scattered when they saw the gun, with Talbot seeking refuge in his mum's house and telling his stepdad to run.

Gleeson fired two shots; one at the front step and another into the front door, with pellets penetrating child's play equipment that was inside.

Defence lawyer Evan Hughes said the risk of injury from the gunshots were low because the men had scattered, the first shot was at a step, there was a pause before the second shot and that shot was aimed at the lower half of the door.

"A car load of people turned up and Mr Gleeson overreacted," Mr Hughes said.

The court heard members of the streets have since had a meeting and the feud has ended.

The court was told Gleeson will have a job when he is released, as well as ongoing support from his partner and family.

"Mr Gleeson now has something to work towards, something to lose," Mr Hughes said.

Gleeson pleaded guilty to two counts of recklessly discharging a firearm. Chief Justice Alan Blow remanded him to reappear on May 22.
