Bullet JacketsAll Sierra Match jackets are made from special gilding metal copper alloycomposed of 95% copper and 5% zinc. In order to match our differentbullet requirements and meet stringent quality objectives, we buy nineteen different sizes of gilding metal and require three times more dimensional and quality control than is considered standard in the copper manufacturing industry.
Special tooling made in our own tool and die shop assures that the jacketis drawn evenly and that uniform wall thickness is maintained for accuracy.Jackets which have been drawn using Sierra's progressive multi-step draw process to the proper wall construction are then trimmed to a length with a tolerance of +/- 0.002". This insures consistent weight and proper forming when the bullet is assembled.
After each step, the bullet jackets are washed and rinsed using a special cleaning process developed by Sierra. During each phase of production, roving quality control inspectors check specifications to ensure that the only part to move on is a perfect one. Reports on the quality of parts being manufactured are maintained in every department and are periodically reviewed by shift supervisors.
