Greetings;
A friend who has been reloading for many years recently gave me a good deal of vintage powder (@30lbs) - rectangular metal 1lb cans, unopened. I queried Hodgdon today and was told that the powder was in all likelihood good to use (when I do open it examine physically and of course be on the look out for acidic smells etc.). They did caution me though that the formulation and hence pressure information *may* have changed from when DuPont manufactured the stuff I have (@30yrs ago) and so should not rely on current load books.
So my question to the group is does anyone have any data for: IMR4831, IMR 3031 and IMR4064 manufactured by DuPont @30+ years ago that they might be willing to share?
I expect to load the powder for a M38 6.5x55Swede, 140gr projectile but any data for 30-06, .308 etc would be appreciated.
Thanks,
