^^^This^^^^^Does the donor know if the powder in the cans is the one on the label?
If open, so long as it passes the visual and sniff tests, that would be my only concern.^^^This^^^^^
While possible, id think that would be stupid. But doing stupid things isnt impossible.Maybe I’m extra cautious, but I won’t use an opened powder from someone else, because they could’ve put a different powder in there.
^^^ ThisThe can on the right doesn't even count as " old " .
Give the other the visual and sniff test . If it passes those , load identical loads with each can's powder , and chrono back to back , to see if within the usual lot to lot variations .
So long as whomever was alive and could tell me its the right powder in there, good enough. Maybe I wouldn't accept powder from an enemy or disgruntled neighbor, or the dude whose wife I was banging.While possible, id think that would be stupid. But doing stupid things isnt impossible.
If for some reason they did...you'd think they would mark it as such. Usually powder isnt something I'd be swapping containers, since every powder has different load characteristics and burn rate.
And what if you don't have a chrono?The can on the right doesn't even count as " old " .

It was only in Dad's last years reloading that he had a chronograph - he had one of the old ones you had to shoot through.
I don't yet have one - I'm thinking about saving my pennies and investing in a Lab Radar chrono - those seem to do pretty well and they seem to be simpler than many other options.
I don't disagree - I'm not sure how I'd make use of the cheap Caldwell at AGC though, which is the main reason I have yet to invest in one.Starting at under $99 , there is no reason to not have one . They are too important not to .
Even the cheapest is more than accurate enough , and consistent with themselves .
What’s to risk? It’s IMR 3031 - the formulation has been unchanged since 1934. Unless the powder has an off smell or color, it’s good and will function just as it did when it was put in those cans.Over abundance of caution on my side, but unless I know for certain how it was stored, and what's exactly in the containers - I'm not going to risk it.
That's info I just learned, regarding IMR 3031.What’s to risk? It’s IMR 3031 - the formulation has been unchanged since 1934. Unless the powder has an off smell or color, it’s good and will function just as it did when it was put in those cans.
