I've done this before now but I brought another Accurate molds 215 gr. mold(and yes, it's a SWC) and I've forgotten what was the powder weight I used. I'd like to use HP-38 (W-231). this mold was quite accurate in my model 28 S&W but it's been a long time since then. actually it pours out at 223 gr's.(a lot of lead in my lead pot. and yes, I"ll be using .38 special cases. the Lyman book and hodgdon book only go up to 170 gr.s. I"m thinking of about 3.5 gr.s of 231 max. loaad??? anyone!
