In my experience, the following loads in 9mm Luger have worked well. By the way, what do you mean by "target loads", the following loads work in IPSC Competition (minor caliber)
5.2 Gr. Unique, 125 gr. RN Hard Cast Lead, sized .357" dia
5.9 Grains Accurate #5, same bullet. OAL with each load is approximately 1.165"
WORK UP TO THE ABOVE LOADS, FROM BELOW.
