Back boreing or over boreing is when you open up the barrel of the shotgun a few thousands of an inch to help reduce the friction of the wad and shot column in it's passage through the barrell. It helps create a better, tighter pattern in many cases. Many factory target shotguns are already backbored to a certain extent.
