Does anyone have a fairly comprehensive source on this? Given the ammo shortages and the internet, a whole lot of us have acquired a lot of different brands, such as Sellier and Bellot, PPU, Fiocchi etc. (I name these in particular, since they happen to be what I have a good bit of).

Doing a little internet search, there's some suggestion that these European rounds are hotter than, say, WWB or Blazer.

I've found a couple sites on ballistics, but they're incomplete (one says S&B "coming soon" and PPU isn't listed; but it DOES have Fiocchi significantly higher than WWB and Blazer).
