As most mentioned... Unique under any bullet, ranged for whatever weight and velocity you want.
I've also found some other good alternates... like RedDot/Promo, and even something like TiteGroup will work, although because of how hot TG burns, I don't like it particularly for indoor shooting of cast bullets.
Given the sedate velocities you are looking for, I would not go any slower than Unique/Universal/AA#5, and the lighter the bullet, the faster my powder would get. Unique works well with 250-270grn bullets, but I'd pick something like RedDot for sub-225grn bullets.
