AA5 has been made in South Africa, Israel & the Czech Republic that I know of (and have had cans so marked) and the data, while fine if loaded by weight, can get crazy if you are using a volume measure & have to change while in the middle of a run. Densities vary by as much as 40% !!
Had this happen while loading 9mm on a Lee press w/Lee measure.
Fortunately, the powder looked different enough in color that it caught my attention.
I had gotten 5 or 6, 1# cans from the SAME SUPPLIER IN THE SAME ORDER. From the 3 different countries mentioned !
I made a vow after that....I no longer use ANY powder from AA !
Just another good reason that I use Vhit powders in most everything now.
Note to WiskyT....
They even BRAG about Unique being "New & Improved" as far as being cleaner. They must have changed something in it.
But I have to agree, a lot of the new data seems to have been written by corporate liars....er... lawyers.
All the more reason to own a good chrono !
Yes, they changed the base material (linters?) of Unique from one type of fiber to another so it burns cleaner. I think it is an ancillary benefit of the change to a different production facility rather than a deliberate attempt to make a cleaner burning product based on what I read at the time. Regardless, they went to a lot of trouble to make sure it performed the same as it always had since it would be irresponsible to do otherwise.
