I don't have any lists. I would imagine that the conversion from the warmaster stats would be almost exact. For warmaster each stand had a number of attacks and a number of shots.
For most shooting units it was 3/1. I'd imagine for non-fantasy humans it would be more like 2/1. So you get the 6/3 shots for Black Powder.
If I were going to do it, that is how I would convert it.
So Orcs would be 12/0 attacks 3 hits 6+ save.
Goblins would be 6/3 attacks, 3 hits short range, say 9" no save
Black orcs would be 12/0 4 hits 5+ save
Trolls 15/0 3 hits, 5+ save
Ogres 12/0 4 hits, 5+ save
Boar riders 12/0 3 hits, 5+ save
wolf riders 6/3, 3 hits, 6+ save short range shooting
wolf chariots 9/0, 3 hits, 6+ save
Giant 8/0, 8 hits, 5+ save can be wounded giant rules
And on and on. If you want arrer boyz they would be:
9/3, 3 hits, 6+ save normal shooting.
If you don't have a copy of warmaster it might be more difficult but this is how I would do it.
