Got the 4 5/8 Ruger Flat Top and want some load info using Unique and a 240 Gr Cast. Years ago I used the Skeeter Load of 7.5 Gr of Unique but at my age want a softer shooting load. Am looking for a much lighter load using Unique and a 240 Gr Cast. How low can I go for something around 800 FPS. Or should I be using another powder. Have Tite Group and HP-38. I want this for a fun load to roll tin cans and such. Not for hunting since I am just a shooter now a days.
