I just got some 358 dia. SWC gas checked bullets with an adverage weight of 175 grains. With it I got a lot of ww 571 and ww 540 which is th e same as HS7 and HS6 in that order. Also some CCI SPM primers. I would like a moderate to light load with each powder if anyone knows any . Thanks!!!

From the Hodgdon website:

158 GR. CAST LSWC Hodgdon HS-6 .358" 1.610" 6.0 990 12,900 CUP 7.0 1106 15,500 CUP

170 GR. SIE JHC Hodgdon HS-6 .357" 1.580" 8.0 1181 30,900 CUP 9.2 1321 42,900 CUP

So with HS-6 it looks like 6.0gr-7.0gr would be just about right to start with maybe going up to 8.0gr. This is just my rough estimate. 8) 8)
