About the Manufacturer
For over 60 years Sierra Bullets in Sedalia Missouri has been dedicated to the manufacture of the most accurate bullets in the world. This commitment to performance has established a "Tradition of Precision" for which Sierra is known throughout the world.

Some of the most important quality control standards used are:
1. Weight Control of +/- 0.3 grain.
2. Jacket concentricity of .0000" to .0003" on target bullets and .0000" to .0006" on hunting bullets.
3. 100% final visual inspection for external defects. 4. Roving quality control inspectors perform other dimensional checks at the cupping, draw, trim and bullet assembly operations.

In order to accomplish accuracy firing tests, Sierra utilizes our 300- meter underground testing range daily. 200-yard accuracy evaluations are conducted on rifle bullets using a precision unrestricted machine rest. They also conduct daily 50-yard accuracy evaluations on our pistol bullets using a specially designed machine rest. If a group does not meet their high expectations, the production run is rejected.
