Quick Answer
Yes, you can mix different bullet weights in a 6x47 Lapua mag, but it's essential to consider the ballistic coefficients, sectional density, and intended use of the load.
Choosing the Right Bullets
When selecting bullets for the 6x47 Lapua, it’s crucial to balance ballistic performance, weight, and cost. For varmint hunting, you can mix 55-90 grain bullets. The 55-grain bullets are ideal for high-velocity, long-range shots, while 80-90 grain bullets provide better expansion and penetration at closer ranges.
Load Development and Safety Considerations
When mixing bullet weights, it’s necessary to develop separate loads for each weight to ensure optimal performance and safety. Start with a base load case of a single bullet weight and then adjust the powder charge as needed to achieve the desired velocity. Always use a chronograph to measure the velocity of each load, and never exceed the maximum safe powder charge. For the 6x47 Lapua, a maximum safe charge can be around 33-35 grains of Varget.
Practical Tips for Field Use
When hunting varmints with a 6x47 Lapua, it’s essential to practice shooting with different bullet weights in various conditions to develop muscle memory and confidence. Consider using a scope with a ballistic reticle to help compensate for wind drift and bullet drop. Always carry spare ammunition, and make sure to check the conditions and adjust your shot accordingly.
