Cases expanded to 0.4260" / 0.4260", primers slightly to moderately flattened, cases look good, one some stress.

Kinda looks like Ramshot Silhouette (including considering the charge weight) or something else similar looking to me.  Aren't those flakes a little big for AA#5, or does AA#5 really look like that?  I have AA#7 and AA#9, but no AA#5 to compare, so I'm not sure.

Well that is much different than what they put in their Magnums.

Is PPU a Serbian company?  Do they load it in the USA?  If not, it really could be hard to guess what powder it is if loaded in Serbia.

Even if it wasn't loaded from a bottle that reads AA#5 it still likely is.  Lots of powders we see on the shelf here in the US are actually made in Europe then retail packaged here.

Wow.  You'd probably have to get out and push their .40's.
