Ok to start I'm loading 40s&w 180gr Berry's FN. I'm pushing it with W231. I'm trying to use up these 180. I researched this and it looks like Lyman 49th has the load at 5.0gr of 231 with a max of 5.6gr at a OAL= 1.115". the Hodgdon site has this load starting at 4.1gr and Max at 5.0gr. With a OAL=1.125". After much other research I started my loads at 4.1 and worked up to 4.6th with a OAL= 1.125 +- .001. What do you think? It's just odd there such a large difference. I'm looking to work up a load that's reliable and as soft as I can go with out changing springs. THANKS!!
