WS2, the slowest I have gone is Unique/Power Pistol/Universal. Very light loads that just barely cycle the gun show less flow, standard velocity loads show a little more.
45 Vet, I picked up a 15 pound can of Bullseye cheap so I have been using that for most loads. Loads are nearly the same as you listed, with the same result.
If I wanted anything more than factory type velocities I would switch to small rifle primers.
