You can use heavier bullets in .380, but you aren't going to get much velocity with standard pressure. They may not chamber all the way either. I use the Lee 356-102-2R for my .380's. Sized to .357 and loaded to .965 OAL they work great. Probably the easiest way to lube your bullets, especially pistol bullets, is to push them through the Lee sizer which mounts to your press then dip the shank in liquid alox and let dry. It is more messy and not as fast as a lube sizer machine but they shoot just fine in my experience.
