Is brass quality crucial for reloading 6x47 Lapua effectively?

Brass Selection Criteria

When selecting brass for 6x47 Lapua, look for manufacturers that offer high-quality, precision-made cases. These cases should be made from a high-strength, high-tensile alloy that can withstand the high pressures generated by this cartridge. For example, Lapua’s own brass is an excellent choice, but other reputable manufacturers like Norma and Hornady also offer high-quality options.

Reloading Considerations

To get the most out of your 6x47 Lapua, it’s essential to follow proper reloading techniques. This includes measuring and sorting your brass to ensure consistency, using a reliable and accurate powder charge, and seating the bullet to the correct depth. For this cartridge, a minimum of 2.7" (68.58 mm) of case length is recommended to achieve optimal performance. A precise case fill with 42-43 grains of H4350 or H1000 powder is also crucial for achieving the desired velocity and accuracy.

Inspecting and Preparing Brass

Before reloading 6x47 Lapua, inspect your brass for any signs of damage or excessive wear. Check for dents, scratches, or other imperfections that could compromise the case’s integrity. If you find any damaged brass, set it aside for other uses or discard it altogether. For optimal results, use a case trimmer to trim your brass to the recommended length, and then deburr the case mouth to prevent any potential issues during reloading.
