Hello from Scotland

I believe this has been covered not that long ago, so "sorry " to cover the same ground but ive looked back and cant find it.

How fast do modern smokeless powders degrade once a tub is opened ? If im given a tub that has been part used then left on a self for 10 years or more does it still have the same properties ? will it still burn at the same speed ?

Would be interested to know ?

regards Englander

Hi, Englander:
   Here's the link.
http://beartoothbullets.com/cgi-bin....2;t=166

   According to VihtaVuori, the burning rate increases if the powder dries out. New powder has about 1% moisture. They dried a sample to 0.5%.  Pressure went from 46500 psi to 51500 psi and velocity incresed from 2530 fps tp 2590 fps.

Bye
Jack
