Description
Vihtavuori N568 is a slow-burning rifle powder engineered for large magnum cartridges where high performance is essential. Known for its consistent and stable burn rate, N568 is particularly suited to applications involving heavy bullets and long-range accuracy. It is a double-base, extruded powder with fine granules that facilitate smooth metering through powder measures, enhancing precision during the reloading process. As a slower burning propellant, N568 provides optimal pressure curves for larger case volumes, ensuring complete and efficient combustion. Celebrated for its exceptional temperature stability, N568 minimizes deviations in velocity across a wide range of environmental conditions, making it a reliable choice for competitive and precision shooting. Popular calibers for which N568 is often used include the .338 Lapua Magnum, .300 Norma Magnum, and similar high-capacity cartridges. For load development, handloaders will appreciate N568's forgiving nature, allowing fine-tuning of loads without sudden pressure spikes. Vihtavuori's reputation for clean-burning powders translates into reduced residue, maintaining firearm cleanliness and reducing barrel wear.
