Shadow, it's in my original post. I'm using the newer flattened ball powder. :)

Thanks Nick, I know I had to have read that either here or on GT, just getting a head of myself sometimes!  8)

So....any reported appreciable differences in the two versions? I've got a pound of AA9 I've never used. Had for awhile so it's the older type.

EdMc, you can look at the two pictures and ten look at your's and you should clearly be able to verify which one you have.

They are supposed to be the same by weight, I think the "older microbeads" occupy more space and don't compress as much.  ???

Thanks Wade. I was mostly asking if there had been any mention of velocity/pressure differences between the new and older configurations at the same loadings. I don't regularly frequent as many gun forums as others.
