I have found that 4.0 grs of WST works great , accurate and very clean . My fiance shoots 4.5 grs of Ramshot Zip , accurate and low recoil . Both loads use a 158 gr cast bullet . I'm sure swaged will shoot fine also with the above loads .
The 5.0 grs of Unique has been a favorite of many a shooter . Skeeter Skelton said it was a " good working mans load " . Also using a 158 gr lead bullet . I loaded up some 125 gr lead bullet loads using tite group , very low recoil and seemed accurate . They were being shot out of J frame airweights .
