Vihtavuori N550 Powder Overview

Vihtavuori N550 rifle powder was originally developed for .30-06 Springfield and .308 Winchester calibers and is ideal for many 30 caliber magnums. It’s as versatile as a powder in that it is good for various shooting disciplines and bore sizes. It’s also great for more powerful hunting loads and heavier bullets. This is a medium-burning, high-energy powder.

The N550 is a tubular powder type with symmetrical grain dimensions of 1,0 mm length and 1,0 mm diameter. As with all of our N500 series powders, nitroglycerine has been added to the traditional single-base powder to get better energy content. The burning rate of N550 is similar to that of the N150 rifle powder, and it’s on the medium scale of our high-energy powders. Higher velocity is acquired with equal pressure compared to the N100 series, without increased wear on the rifle!
