Quick Answer
Barrel length has a minor impact on the velocity of 6x47 Lapua bullets, with optimal velocities typically achieved between 24-26 inches of barrel length. Beyond this range, performance may degrade.
Barrel Length and Velocity
The effects of barrel length on 6x47 Lapua velocity are most pronounced at shorter lengths. In a 16-inch barrel, velocities may be reduced by up to 50 fps compared to a 24-inch barrel. However, even at the shortest lengths, velocities remain relatively consistent, typically averaging around 2,700-2,800 fps.
Varmint Hunting Considerations
For varmint hunting, where rapid follow-up shots are often required, a shorter barrel length can be beneficial. A 20-inch barrel, for example, can reduce weight and improve handling while still delivering adequate velocity. However, this compromise may come at the cost of increased barrel wear and potential accuracy degradation.
Optimal Barrel Length for 6x47 Lapua
In practical terms, a barrel length of 24-26 inches appears to be the sweet spot for 6x47 Lapua performance. This length balances velocity, weight, and barrel durability, making it an ideal choice for varmint hunters. When choosing a barrel length, consider the specific requirements of your rifle and hunting application.
