I ended up using H110 for that cast bullet thing I did. I loaded 1000 subsonic rounds and it was fully functional with bolt hold open etc.

Cast bullets are a little (or a lot) different to load but I will definitely try to develop a load for the 190 FMJ with H110.

That stuff meters really well, is available everywhere, and runs clean.
