The barrel is cleaned and checked after every ten rounds or so, or when changing from one type grit to another. Pressure (Fire) Lapping can then be carried out in stages using the loaded cartridges by firing through the barrel a series of lapping bullets impregnated with coarse abrasive, followed in order by the lapping bullets with the medium, fine and polishiing grits. ![]() Using this procedure, it is possible to manufacture in quantity a series of lapping cartridges having coarse, medium, fine and polishing grits impregnated on the bullets. The abrasive-impregnated bullets can then be sized and lubricated and loaded into a cartridge containing gun powder and a wad positioned against the base of each bullet. The abrasive impregnated bullets can then be coated with a protective and lubricating finish, such as carnauba wax, if desired. The mixture is allowed to tumble for a period of time, typically about an hour, after which a sufficient quantity of the abrasive is firmly embedded on the surface of each bullet. The speed of rotation of the tumbler, and the shape of the tumbler are selected so that the bullet/abrasive/tumbling media mix folds on itself, thus providing an even impregnation of abrasive on the bullets and minimizing any deformation of the bullets. The present invention provides a process for simultaneously impregnating a quantity of lapping bullets with an abrasive, in which a quantity of unlubricated bullets are placed in a tumbler with steel balls and quantity of the desired abrasive. To which, Carbone said, "We have a duty to keep people safe.A method for lapping of gun barrels on fully assembied firearms is provided using cartridges fitted with lapping bullets impregnated with abrasive. One said he had a better understanding of why officers behave the way they do. They were taught that a skilled knife man can attack a cop before the officer has time to draw, even if that assailant is 21 feet away.Īt the end of the day, students said they had a new respect for police officers. "I had fun," she said.Īfter learning to handle the weapons, students were suited up and brought into a mock confrontation with a rubber-knife-wielding drunk, played by an officer. Sixteen-year-old freshman Tiffany Barnes said she would love to come back next year and do it again. After the second meeting I thought, `There's nothing better in the world.' " ![]() ![]() After the first meeting, I thought it was all right. "About two years ago, at the high school, (officers) were recruiting cadets (for Police Explorers). "I got the motorcycle guy!" he said, describing his shooting of a criminal in one of the scenarios. When the bad guy fired his weapon, the students shot back with paint bullets, hitting the screen.Īlex Reno, 17, a junior at PHS, said he was having a great time. In a dark room, students watched a simulated crime scene patterned after real ones that have occurred somewhere in the United States. Students got their heart rate up so they would feel what a cop feels when confronting a criminal or entering a dangerous situation, Carbone said. ![]()
