Cartridge chamber insert (Laser bore, light, projectile) for adjusting optics or sights.
Caliber: 7x57R
USE: Store the gun in a firing bench, or similar stable aid. Engage the laser cartridge and insert it into the latest position of the empty chamber of the weapon corresponding to the caliber. If possible, do not close the slide of the weapon - this will prevent damage to the cartridge by the extractor. You may aim at any distance at which the laser will be visible under the conditions (at least 25 yards)
Align the center of the sight crosshairs with the point indicated by the laser. This will give you a rough shot that should "get you on paper". Be sure to remove the laser priming round before loading live ammunition. Store the discharged priming charge in a cool, dry environment. Keep in mind that the laser cartridge provides only a rough loading and you need to fine tune the weapon by target shooting.
