Vihtavouri Reloading Guide

The Vihtavuori Reloading Guide (often referred to as the Vihtavuori Reloader Handbook) is the official load data manual published by Vihtavuori, the Finnish powder manufacturer known for precision-oriented propellants. The handbook provides pressure-tested load data for a wide range of rifle, handgun, and selected shotgun cartridges using Vihtavuori powders from the N100, N300, N500, and specialty series. All data is developed according to CIP and SAAMI standards, offering starting and maximum loads along with corresponding velocities and cartridge overall length (C.O.L.) specifications.

The guide is structured by caliber and bullet weight, listing multiple powder options per cartridge where applicable. It also includes technical background information, such as powder characteristics, burn rate comparisons, safety guidelines, and general reloading procedures. Accuracy loads and compressed loads are clearly identified in the tables, helping reloaders understand performance nuances.

In addition to practical load data, the handbook emphasizes safe reloading practices and encourages users to begin with starting charges and work up carefully. Updated editions are released periodically to incorporate new powders, additional calibers, and revised testing results. Overall, the Vihtavuori Reloader Handbook serves as a comprehensive reference for reloaders seeking manufacturer-approved load data specifically tailored to Vihtavuori powders.
