How Long Does Smokeless Powder Last
How Long Does Smokeless Powder Last. I have seen/heard many rumors and conjecture on powder shortages with hodgdon powder. When properly stored, an unopened container of smokeless powder has an indefinite shelf life, but once it is opened, the stabilizers it contains begin to slowly but surely weaken.
These deliver irrelevant smoke when let go, not at all like the dark that they supplanted. Modern smokeless powder is stable indefinitely when stored at ambient temperatures. If properly stored smokeless powder and primers will last a lifetime and beyond.
