MTB, it is not uncommon for purpose built pigeon guns to have lower swing effort than their weight and barrel length would suggest. This is accomplished by using heavier actions with lighter barrels and stock. Where as purpose built target guns will often use heavier barrels and stock to create higher swing effort which will return as a stable swing and resistance to stopping. Clays, once launched will follow a predictable trajectory aside from air currents. Pigeons are quite capable of suddenly deciding to go somewhere else. The pigeon shooter needs to be able to change directions more quickly/with less effort than the clays shooter. At least in theory and on the average.
