This refers to specific information regarding the propelling charge (powder type and weight) used in cartridges for the 6.5×47 Lapua rifle, often provided by the bullet manufacturer Nosler. This data typically includes specifics like bullet type, weight, powder type, powder charge, overall cartridge length, and expected performance metrics such as muzzle velocity and pressure. An example would be a table outlining several different powder charges for a specific Nosler 140-grain bullet, showing the corresponding velocities and pressures for each load.
Accurate propellant charges are crucial for safe and effective rifle operation. Data from reputable sources like Nosler provides handloaders with a starting point for developing ammunition that performs optimally in their specific rifles while maintaining safe pressure levels. This information is valuable for precision shooting disciplines where consistency and accuracy are paramount. The 6.5×47 Lapua cartridge, known for its inherent accuracy and efficiency, has gained popularity amongst long-range target shooters and hunters. Reliable loading data enhances the inherent performance characteristics of this cartridge, leading to improved accuracy and consistency.
