I have not, but based on Red Dot and Bullseye recipes, I expect a target load can be made with cast bullets like the 145 Lee SWC molds that start at around 3.5 grains. Your main concern will be that a fast powder cannot be loaded to high velocities without creating excessive pressure. It will create less pressure with lighter bullets. So, Green Dots would be just for light paper target-type purposes. That can cause operating problems in some guns, necessitating a lighter recoil spring be installed. It is also not considered a good idea to use polygonal barrels with lead bullets as rapid lead build-up is sometimes observed in them that can create both accuracy and pressure problems.

With a jacketed bullet, like the 155 grain XTP seated to 1.125" COL, you could work up from 3.5 to 4.5 grains in small steps, watching for pressure signs. Again, a powder this fast will not give maximum velocities without exceeding pressure limits, but will give useful velocities.
