I have 2 dedicated .380 molds - the Lee .356-95 RF and the Lee .356-102 RN. Both of these work well enough but I can occasionally find that one odd project pistol that demands a different COL from all the others when using these molds. Then comes the Lee .358-105 SWC pattern. This is the mold I first used in my .380 handloading and found it to be completely reliable for feeding up with every pistol I have used it in. I load this boolit with just a thumb nail thickness of the forward shoulder out of the case and charge the rounds with appropriate powder levels for the weight of the boolit. Against all the odds, I size these at .358 and am still waiting to have a tie-up with the cartridge loading into any pistol. Lee offers this mold (as well as the others I mentioned) in the 6 cavity blocks. I suspect with the proper COL any of these mold patterns will work for you. As for me, I'll stay with the .358-105 SWC.
