The A-10 is a much heavier aircraft than the Hunter - roughly twice the mass (11,000kg vs 23,000kg). Also the 20mm rounds of the Vulcan cannon are considerably lighter (about 100g) than the Aden's (270g). The muzzle velocity is greater (1000m/s vs 800 or so) and the rate of fire is slightly higher (6000rpm vs 5200 rpm), but these aren't enough of a factor to make the A-10's reaction to firing the gun anything like that of the Hunter!
As a young "space cadet" we were at the Holbeach range and watching an A10 doing repeated passes firing that gun and visibly slowing on each occasion. I've never seen a Hunter firing.
BTW - if you were in the RAF aroudn the time of the Hunter, it's very possible you could have bumped into my dad at some point. There are photos for example of him sitting on the wing of a Hunter in Oman. He did about 27 years in all, leaving as a Chief Tech at Brize Norton on MSS
