Moly or other dry coated lead will smoke a good deal less than wax lubed cast.
Bear Creek is good, I got my last from
I have shot Billy Bullets. They don't smoke much but the coating comes off on your hands worse than other brands.
Precision no longer lists revolver bullets, nor does BBI.
I used to shoot a lot of Speer wadcutters but have no recollection of how smoky they were. The rate of fire in PPC is not fast enough for it to matter much.
