hello, i have the lee .45 acp 190 gr swc mold, my question is, i am using winchester 231 with 5.2 gr. of powder. i have been having problem finding what is low and high grain to use. i don't think i am over charging it but would like your input. i have checked several data list and all are for 185 and 200 grain etc. none for the 190 gr. swc.
