Sporting guns or Sporters are mainly designed for clay target shooting. They are nearly always fitted with interchangeable chokes, and have wider top ribs than Game guns – about 10mm. The Sporting discipline is one of the most demanding, and requires a heavier gun to minimise recoil and cope with prolonged use at the shooting range, but still retain some of the feel and pointability of the Game gun. It is not uncommon for sporting shotguns to be fitted with stocks with less drop than Game guns – usually only 10mm across the top of the comb. This is because of the varied targets, like battues and rabbits can result in the shooter placing their cheek in different positions on the stock. With less drop, the shooter is less likely to shoot above or below the target.
