It has been brought to my attention by one of my customers that the government is making the powder now that has a shelf life of about 5 years and after that the powder is no good. Can any one shed some light on this subject. My understanding about powder is as long as you keep it cool and dry it never goes bad. I think it is a way for them to keep us from stock piling our ammo. Has anyone heard anything about this. It is bringing concern from my customers.
