Police found soft-nosed and hollow-point bullets when they raided a pub run by former British middleweight boxing champion Frank Grant, a court heard.
The 15 bullets, and several bullet adapters, were in a plastic bag inside a locked office at the Round Thorn pub in Girlington, Bradford.
Grant, 33, now of Bank Street, Wibsey, Bradford, pleaded guilty to two charges of possessing ammunition in contravention of the Firearms Act.
The city's magistrates ordered him to do 180 hours community service and pay £30 costs.
The court also directed that the bullets be forfeited and disposed of.
Jane Farrar, prosecuting, said Grant was arrested after police searched the pub in January.
During interview, he said his former wife had found the bullets in a bag which had been left in the doorway. He had put them in the office for safety and forgotten all about them.
Grant, now said to be working as a lorry driver, claimed he thought the .22 calibre bullets were blanks or ornamental.
Grant - who was known as the Terminator at the peak of his career - became British middleweight champion in 1992 when he beat Herol "Bomber" Graham.
He has one successful defence when he beat John Ashton at St George's Hall, Bradford, the following February before he lost the title later that year to Neville Brown in London.
After he retired from boxing Grant and his then wife Kate went into the pub trade. They ran the White Bear in Leeds Road, Bradford, before taking over the Round Thorn.
Following the break-up of their marriage Grant lost a legal battle to take over the running of the pub which had been licensed in his wife's name.
The city's licensing magistrates rejected his application in January after they were told that police objected to him being the licensee as he had been arrested three times for alleged assaults on customers.
