![]() Martin started producing Drum and Bass in 1995 and his first signed release was credited under the now defunct Quadrophonic label owned by U2. He is a classically trained musician playing a variety of musical instruments eventually becoming a self-taught music producer. He originally started producing at a young age and has spent many years refining his sound. Good performance requires a concentric, straight bore that accurately centers the projectile within the barrel, in preference to a "tight" fit which can be achieved even with off-center, crooked bores that cause excessive friction, fouling and an out-of-balance, wobbling projectile in flight.įreebase Rate this definition: 0.0 / 0 votesĬalibre, birth name Dominick Martin, is a Drum and Bass, and Liquid Funk, music producer and DJ hailing from Belfast, Northern Ireland. Measurements "across the grooves" are used for maximum precision because rifling and the specific caliber so-measured is the result of final machining process which cuts grooves into the rough bore, leaving the "lands" behind. In a rifled barrel, the distance is measured between opposing lands or between opposing grooves groove measurements are common in cartridge designations originating in the United States, while land measurements are more common elsewhere in the world. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Barrel diameters can also be expressed using metric dimensions. For example, a "45 caliber" firearm has a barrel diameter of roughly 0.45 inches (11 mm). In the United States it is expressed in hundredths of an inch in the United Kingdom in thousandths and elsewhere in millimeters. It is measured in inches or in millimeters. ![]() In guns, particularly firearms, caliber (or calibre sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification.
