I use a lot of VV powder in 9mm and was surprised to see on their website that the shelf life is at least 10 years.
The estimated shelf-life of Vihtavuori gun powders is a minimum of 10 years, if stored and sealed in its original containers at a temperature of circa 20°C/ 68°F and a relative humidity of 55-65 %.
Hopefully that's an extremely conservative estimate on shelf life otherwise I might be losing powder in 4-5 years....
This was an interesting thread on VV N150 going bad. Had some nasty fumes coming from the jug.
Not something I'm going to lose sleep over but I guess it's something I'll have to keep an eye on.
