Accurizing is the process of improving the accuracy and precision of a gun (firearm or airgun). [1] For shooting sport, accuracy is the gun's ability to hit exactly what the shooter is aiming at, and precision is the ability to hit the same place over and over again in a
Increasing the barrel length will increase the swept volume linearly, while increasing the diameter will increase the swept volume as the square of the diameter. Since barrel length is limited by practical concerns to about arm's length for a rifle and much shorter for a handgun, increasing bore diameter is the normal way to increase the ...
Subsequently, the case was shortened to reduce powder capacity to a volume more suited to the shorter barrel of a pistol. The resulting cartridge, the .221 Fireball, produced factory-loaded velocities of over 825 m/s (2,700 ft/s) from the short barrel, and accuracy rivaling the parent .222 Remington, one of the most accurate cartridges made.

In this case they tested a wide variety of ammunition available in .38 and .357 magnum using a single revolver modified to have a long barrel (so that they could cut it down an inch at a time, as they did with the barrel length tests) and also modified to allow them to change the gap using a set of shims. In this way they were able to test with ...
The gun's barrel has a 7 groove right hand twist, and the proprietary integrated accessory rail only fits a Hi-Point LaserLyte laser sight or ¾ inch laser ring. Due to the fixed barrel, accuracy is well above average, on par with higher priced pistols [ 1 ] this weapon remains popular due to its low cost and lifetime, no questions asked ...
Length: 245 mm: Barrel length: 150 mm (6 Inch) Cartridge ... Margolin's raised plane of sight is a deliberate design feature that increased the accuracy of the pistol ...
The length of the barrel (especially for larger guns) is often quoted in multiples of the caliber, used, for example, in US naval rifles 3 in (76 mm) or larger. [2] The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a dimensionless quantity.
Three pistols went through a 30,000-round endurance test and maintained accuracy of 2.5 in (64 mm) at 25 meters; only the O-ring needed replacement after 20,000 rounds. The weapons worked in temperatures from -25 degrees Fahrenheit to 140 degrees Fahrenheit while exposed to mud, ice, and sand.
