Sean Murphy, 38, from Doncaster, had seen his GP repeatedly about the problem and also tried a variety of traditional ointments and creams.
But when the persistent wart refused to disappear, he opted for the firepower of a 12-bore Beretta he claimed he had found under a hedge a few months earlier.
Heavy-handed: Sean Murphy pictured after the accident in which the middle finger of his left hand was blown off by a shotgun
His technique successfully removed the wart - along with most of the middle finger of his left hand.
And the solution also landed Murphy in court this week for illegal possession of a firearm.
After leaving Doncaster Magistrates' Court with a suspended 16-week prison sentence, Murphy said: 'I'm happy with that.
'I know I could have gone to jail for up to 15 years for a firearms offence. My solicitor did a very good job. The best thing is that the wart has gone. It was giving me lot of trouble.'

Murphy was employed as a security officer at Markham Grange Nurseries in Doncaster at the time of the incident in March, but has since lost his job.
He had suffered with the irritating wart on the joint closest to the tip of his middle finger for more than five years.
He said he drank several pints of beer to build up his courage before carrying out the operation outside the caravan where he was living at the time.
He stretched out his left hand, pointing the end of the barrel at an angle to the offending wart, and used his other hand to hold the stock steady and pull the trigger.
