This is about a style of gun handling and shooting.

The theory was that people can shoot well when they rapidly mounted the gun and "slapped" the trigger as soon as the butt was securely on the shoulder. This seems to me to be a melding of swing through with spot shooting as opposed to sustained lead. "Mr. Churchill" was a good salesman and shooting coach as this style and the guns that go with it gained a noticeable following.
The fly in the ointment is that shooting will frequently have longer shots that are better shot deliberately. Most shooters find it difficult to achieve a smooth swing with guns having low swing efforts. "Starts in a wink, stops in a wink, changes direction in a wink," is a pretty fair description of Churchill XXV handling.
A friend shoots "XXV" type guns way better than I shoot any description. Of course, he has the reflexes and muscle speed of an inspired cat.
