I try not to load too many 380 rounds, I use the Berry bullets for the 380 I load. Seems like the little bullets would be a pain to cast and then run threw the lube/sizer.
But I do see the new Lyman cast bullet book gives several loads for the Lyman 356242 in 120grain RN for 9MM and 380 ACP. Pretty heavy bullet for the little gun but you could use one mold for both guns.
