Description
Vihtavuori N565 is a slow-burning rifle propellant specifically designed for long-range precision shooting and heavy bullet loads. Its slow burn rate is ideal for magnum-sized cartridges, making it a preferred choice for calibers such as 7mm Remington Magnum, .300 PRC, and .338 Lapua Magnum. The powder is extruded in form, but its granule size is engineered for smooth metering through powder measures, ensuring consistent charge weights during the loading process. N565 distinguishes itself with remarkable temperature stability, maintaining consistent pressures and velocities across a broad range of environmental conditions, which is critical for long-range accuracy. For reloaders, load development with N565 may require careful consideration of compressed loads due to its optimal performance with full case capacities. This powder is lauded for its ability to achieve high velocities while maintaining precision, making it a reliable choice for handloaders who demand repeatable results and exceptional ballistic consistency. Vihtavuori's reputation for quality and consistency is well-regarded in the reloading community, providing confidence in every load.
