Rotherham Chantry Rifle Club, based in a former quarry at Hoyle Croft Lane in Braithwell, has been given the go-ahead to raise the height of walls on its site, called 'butts', which are put behind targets to stop shots.
Doncaster Council planning committee approved the change at its recent meeting after having deferred a decision last month.
Local businessman Arnold Pawson had raised fears that the application may allow an increase in the calibre of the guns, as well as concerns over disruption during construction, and the impact on wildlife.
He told councillors he had been an honorary member of the club for 40 years and lived close to the site
But club chairman Dave Boden-Hook said the club has been shooting at the quarry for the best part of 50 years, with Olympic quality shooting.
He told councillors the change, which will see the butts raised from 2.8m tall to 6.1m tall, was needed because of a different interpretation of the regulations by the MSRA's certification offcer.
He said: "We have no intention whatsoever of increasing the calibre of weapons on the range."
