Lots of info there, there are many videos so eveyrone can look at them, maybe even find "their" ammo and draw their own conclusion. The 4" bbl of the luger will yield even lower velocity than the 4.5 to 5.1" bbls noted in that video
There are at least two PPU videos, check them both out. One uses an 7.8" bbl.
If you looked at the post, you know what is in it. I did a post with nato info; please do post a link to it so we can all find it again!
As you say the info is there, one just has to look.
