A Lincoln man who had a stash of illegal ammunition has been given a suspended jail sentence at Lincoln Crown Court.
The 50 expanding bullets were found when Jonathan Charlton was being evicted from his rented home in Laceby Street.
Phil Howes, prosecuting, said that police were called as Charlton was removing his belongings and the bullets were discovered.
Mr Howes said: "These were bullets designed to expand on impact. He knew these items were there. He said he had no idea where they came from."
Charlton, 31, now of Walford Drive, Lincoln, admitted possession of prohibited ammunition on 15 August 2012. He was given a six-month jail sentence suspended for a year with 12 months supervision. He was given 150 hours of unpaid work and ordered to pay £340 prosecution costs.
Judge Michael Heath told him: "The circumstances of how you came into possession of these bullets remains something of a mystery. They could have found themselves in criminal hands. That is the seriousness of this case."
Andrew Kerrigan, defending, said Charlton discovered the bullets several months earlier following a party at his home. He believed one of the party goers may have left them on the premises or that the bullets were in the house before he moved in.
"He is not a man who has any interest in firearms. He accepts he made a grave error of judgement. On discovering the ammunition he should have contacted the police."
Mr Kerrigan said Charlton appeared to have been living "a student lifestyle" at the time and needed to grow up.
He said Charlton was being evicted for rent arrears but now has a new home and is working.
