Description
Vihtavuori N150 is a medium-slow burning rifle powder known for its versatility in a variety of calibers. This extruded (stick-type) powder is designed specifically for larger rifles, making it a popular choice among handloaders working with calibers like .308 Winchester, 6.5x55 Swedish, and .30-06 Springfield. N150 possesses excellent metering properties despite its extruded form, ensuring consistent charge weights and reliable performance in precision applications. Renowned for its temperature stability, N150 maintains consistent velocities and pressures across a wide range of environmental conditions, reducing the variables involved in load development. This characteristic is particularly advantageous for shooters who demand accuracy and reliability in varying climates. During load development, handloaders will appreciate its forgiving nature when nearing maximum pressure limits, allowing experimentation within safe boundaries. Vihtavuori's reputation for manufacturing high-quality propellants gives handloaders confidence in N150's performance, providing a dependable option for those seeking precision and repeatability in their rifle loads.
