I picked this up in my lot of stuff this week. Most of these containers are full. But I don't know how old they are. How can I tell if powder has gone bad? Should I use them or get rid of them?
Alliant did clean up Unique a bit over the old Hercules formula. For some forgotten reason (probably was cheaper), I shifted over to using Hodgdon Universal Clays for a few years because it was almost a grain-for-grain equivalent to Hercules Unique - and was delighted to find that it was noticeably cleaner-burning in the handgun cartridges and shotgun gauges I reloaded. When Alliant introduced their cleaner version of Unique, I shifted back. Alliant/Hercules is my all-time favorite line of gunpowders.carl418 said:xtm,
What about the 'dirtiness' of the old vs new?
I've yet to have to do that. If it ever comes to it, I'm not even sure I could.. it might be too traumatic for me! :lol: :lol:However, if I am "unsure" as to how it's been stored over it's life time, it becomes fertilizer.
I have to respectfully dissagree with this statement.Just use reloading data from back in those years. Do NOT use "new" reloading data for old powder, as the formulation may have changed and could result in undesirable pressure problems.
