Quick Answer
The 6x47 Lapua is generally effective up to 400 yards for varmint hunting due to its relatively flat trajectory and manageable bullet drop.
Ballistic Performance
The 6x47 Lapua cartridge is known for its flat trajectory and moderate velocity, making it suitable for varmint hunting at longer ranges. With a typical bullet weight of 80-100 grains, the cartridge’s ballistic coefficient (BC) ranges from 0.4 to 0.5, which is relatively good for a varmint cartridge. This results in a bullet drop of around 12-18 inches at 400 yards, depending on the specific load and rifle setup.
Hunting at Long Distances
When hunting varmints at longer distances, it’s essential to consider the bullet drop and wind drift. Aiming high and compensating for wind drift can help ensure a successful shot. For example, at 400 yards, a 10 mph crosswind can result in a 20-30 inch drift, so a precise aiming point is crucial. Aiming for 2-3 inches high above the target’s eye level can help compensate for bullet drop and ensure a clean kill.
Rifle Setup and Load Selection
To effectively hunt varmints at longer distances with the 6x47 Lapua, it’s essential to have a well-established rifle setup and load selection. This includes a rifle with a high-quality scope, a consistent trigger, and a well-balanced stock. A load with a BC of 0.45 or higher and a muzzle velocity of 3,000 ft/s or higher can provide the best balance of range and accuracy. Additionally, a good understanding of the ballistic tables and a precise aiming technique can help ensure a successful shot.
