I was loading 9mm lead with TG. My oal was 1.136. The bullet shot good and all was fine. Now I wanna switch powders to WSF. The only data I find is on Hodgdon for a 124gr .355 lead bullet. Mine is 125gr..356 RN bullet. The data says start at 4.0 grs and max at 4.7 grs. With a OAL of 1.169". Is the .001 dif in dia. a big deal. And the oal it gives is pretty long it's actually at the lube line. I like the 1.136 OAL for my gun. I know that seating deeper will cuz more pressure. Is that start charge good for that bullet dia?
