I use the same 63.0grs AR2209 as VG posts above with his 350gr and my 400gr bullets for the same accuracy results and have also tried VG's red dot plinking load with his 350gr cast bullets too and it is a pleasant accurate load to use.
My cast alloy is about Lyman #2 although at the moment have Winchester hard shot in ingots but it needs a bit more tin I think to cast properly.
