My go-to target load is 8.0 grains of Unique with any bullet...
7.0 grains of Winchester 231/HP38 works just about as well.
If one is getting unburned powder it is usually because there isn't enough bullet pull for the given load and the pressure drops before all the powder burns. I have gone to the Lee Carbide Factory Crimp die and put a very heavy roll crimp on all loads, target and heavy and never have unburned powder.
