Sierra 10mm .400 165gr JHP Bullets /100

Sierra Sports Master 10mm .400 165gr JHP Bullets /100

These bullets are designed to meet even the most demanding shooter’s needs. This bullet was introduced in 1992. The International Practical Shooting Confederation needs only 1000 fps muzzle velocity with the 165 grain #8445 to make “major.” These power factors are easily attained with the heavier bullets in the 10mm Auto or 40 S&W. One also can use any of these bullets in an “old timer,” the 38-40 Winchester (38 WCF), made popular in both single-action revolvers and rifles for Cowboy Shooting. However, these bullets are not legal for competition. Special provisions may be required for crimping (since these bullets have no cannelure for roll crimping) and expanding ball size in reloading dies for the 38-40.

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.
