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:
“I do not know if you remember the tale of the girl who saves the ship under mutiny by sitting on the powder barrel with her lighted torch ... and all the time knowing that it is empty? This has seemed to me a charming image of the women of my time. There they were, keeping the world in order ... by sitting on the mystery of life, and knowing themselves that there was no mystery.”
—Isak Dinesen [Karen Blixen] (1885–1962)
“To find the length of an object, we have to perform certain
physical operations. The concept of length is therefore fixed when the operations by which length is measured are fixed: that is, the concept of length involves as much as and nothing more than the set of operations by which length is determined.”
—Percy W. Bridgman (1882–1961)
“We approached the Indian Island through the narrow strait called “Cook.” He said, “I ‘xpect we take in some water there, river so high,—never see it so high at this season. Very rough water there, but short; swamp steamboat once. Don’t paddle till I tell you, then you paddle right along.” It was a very short rapid. When we were in the midst of it he shouted “paddle,” and we shot through without taking in a drop.”
—Henry David Thoreau (1817–1862)
“All catches alight
At the spread of spring:
Birds crazed with flight
Branches that fling
Leaves up to the light”
—Philip Larkin (1922–1986)
