Anyone done any Temp stability/velcoity testing with N160 or other vihtavouri powders?

Luke45,
Need to search for Dr. Denton Bramwell, don't a fair amount of honest scientific studies on the subject.
The bulk of his work on this would suggest that the whole Norton is over-plasyed to a large extent. Hot guns, with rounds cooking in the chamber mess with everything, no powder is immune. Search him out, he posts once in a blue moon on shooters forum and the campfire.
