Barrel Length and Shot Spread
Shortening the length of a shotgun barrel does not significantly affect the pattern or spread of the pellets until it is decreased to under 50% of a typical barrel length. The pattern is primarily affected by the type of cartridge fired and the choke, or constriction normally found at the muzzle of a shotgun barrel. Cutting off the end of the barrel removes the choke, which generally only extends about two inches (about 5 cm) inward from the muzzle. This results in a cylinder bore, which causes the widest spread generally found in shotgun barrels. For an even wider pattern, special "spreader chokes" or "spreader loads" can be used, that are designed to spread the shot farther. (See choke for more information on the impact of chokes. See shotgun shell for information on spreader loads.) See details on shot patterning.

Famous quotes containing the words barrel, length, shot and/or spread:
“Peaches grow wild, and pigs can live in clover;
A barrel of salted herrings lasts a year;
The spring begins before the winter’s over.”
—Elinor Wylie (1885–1928)
“Punishment followed on a grand scale. For ten days, an unconscionable length of time, my father blessed the palms of his child’s outstretched, four-year-old hands with a sharp switch. Seven strokes a day on each hand; that makes one hundred forty strokes and then some. This put an end to the child’s innocence.”
—Christoph Meckel (20th century)
“I’d rather you shot at tin cans in the back yard, but I know you’ll go after birds. Shoot all the bluejays you want, if you can hit ‘em, but remember it’s a sin to kill a mockingbird.... Mockingbirds don’t do one thing but make music for us to enjoy. They don’t eat up people’s gardens, don’t nest in corncribs, they don’t do one thing but sing their hearts out for us. That’s why it’s a sin to kill a mockingbird.”
—Harper Lee (b. 1926)
“The philanthropist too often surrounds mankind with the remembrance of his own cast- off griefs as an atmosphere, and calls it sympathy. We should impart our courage, and not our despair, our health and ease, and not our disease, and take care that this does not spread by contagion.”
—Henry David Thoreau (1817–1862)
