Re: Old powder
The best way I know to determine if the powder is unsafe is to smell it. if it smells like acid then it has gone bad.
If it is in the old paper cans it has probably gone bad and will show signs of rust on the lids.
Being old dose not make it bad only the method of storage and the amount of air aloud to inter
the container. (Number of times it was opened).
Cartridges can be over 100 years old and still work well because they were sealed well.
One of my best powders has been H4831 that was un-loaded 20mm rounds from WW2 that got Hodgdon started in the powder business.
With age it seems to mellow a bit until it starts to break down and turn corrosive (Hence the smell
So If it stills smells fresh and shows no signs of brake down It should be good to use. As always
with any new/old batch of powder, start low and work up.
