[QUOTE="Dean2, post: 1956263, member: 26077"] Blackpowder will keep for 300 years and fire exactly the same as the day it was made. I tested a can of FFFg over a 15 year period and there was zero change in velocity. BH 209 is NOT like Black Powder. Western claims indefinite shelf life. It truly will go bang for many many years but if you measure velocity when it is new and the same load 3, 5 and 7 years later from that same can, it is not going to be the same. All of the times I have tried this, velocity decreases the older the powder gets. So long way of saying, go ahead and use the old powder but use new stuff for final sight in and hunting. You can easily check velocity on your stored powder versus your new stuff, unopened cans do not seem to show the velocity drop near as fast or pronounced as an open can. All in however, it is still far and away the best of the BP substitutes and does not drop velocity at anywhere near the rate that some of the others do in storage, American Pioneer being among the worst. It has a shelf life of maybe a year. [/QUOTE]
