PMC and IMI 62gr M855 is probably the closest you can get.
Ruag as an ammo maker also makes 55gr M193, 62gr M855/SS109 and 63gr GP90.
Places in the US were advertising the Ruag M193 last year and I was pretty jealous.
It was on the PE90 stripper clips no less.
I actually bought a thousand round case of GP90 from either P&D or Wolverine more than six years ago.
They had it on sale for some kind of one day special at either $300 or $350.
It was a crazy clear the floor kind of price and I wish now, that I spent my life savings on it then.
