10-15grs of blue dot works well with any of the pistol bullets. IIFC 125HP can only go about 2200fps before it becomes a .358 shotgun but is incredible to hit small furry things with and offers minimal recoil. The lightest I have gone is about 5grs with a 158 cast and that only offered about 850fps. I believe others have gone lighter with bulleye but you run the risk of sticking a jacketed bullet at those speeds.

Hunt hard, kill clean, waste nothing and offer no apologies.
