Vihtavuori Powder

Vihtavuori load data provides manufacturer-tested reloading tables for their powders, showing cartridge, bullet weight/type, recommended primer, test barrel length, and safe charge ranges (without repeating exact charges here). Load data is produced under controlled conditions and is the authoritative source for matching Vihtavuori powders to specific cartridges. To use it safely, select the exact cartridge and bullet listed, start at the manufacturer’s published starting entry, and work up incrementally while observing for pressure signs such as flattened primers or difficult extraction. Always use precise tools—digital scale, calipers, reliable press, and chronograph when possible—and keep detailed records of component lots and test results.
