Quick Answer
To achieve optimal performance when handloading the 6x47 Lapua for varmint hunting, use a 43-44 grain bullet, a case capacity of 43-45 grains of water, and loads with a maximum pressure of 52,000-54,000 psi. This will provide a balance of expansion and penetration. Use a consistent charge weight and carefully monitor case fill to ensure optimal results.
Optimal Bullet Selection
When selecting a bullet for the 6x47 Lapua, consider a 43-44 grain weight with a BC of 0.55-0.60. This weight range will provide sufficient expansion and penetration for small varmints, while the BC will ensure a flat trajectory. Examples of suitable bullets include the Hornady 43 grain V-Max and the Sierra 43 grain Tipped MatchKing.
Load Development and Case Capacity
To achieve optimal performance, ensure a case capacity of 43-45 grains of water. This will provide a sufficient margin for expansion and prevent over-expansion, which can lead to unreliable results. When developing a load, start with a minimum charge and gradually increase the powder charge in 0.1-0.2 grain increments, monitoring pressure and case fill to identify the optimal load.
Load Management and Pressure Control
To ensure consistent results and prevent over-pressure, use a consistent charge weight and carefully monitor case fill. A maximum pressure of 52,000-54,000 psi is recommended for the 6x47 Lapua. Regularly inspect cases for signs of over-pressure and adjust the load as needed to maintain a safe and optimal performance level.
