I was just experimenting tonight with my Lee 358-158 RF boolit. Just for the heck of it, I seated it in a 9mm case so that the boolit was just touching the lands. My COL turned out to be 1.100". I put this dummy round in the magazine and it fed just fine in my Sig P228. Anyone have any idea what kind of charge to start with using titegroup or w231? These boolits will be sized to .358 (barel slugged at .3565"). I figured on reducing the 147 grn lead bullet data by 20% and working up from there. Any advice wold definately be appreciated. Thanks!
