What is the difference between a .380 .355 dia bullet and a 9mm .355dia bullet?

You will find with a little additional reading and exploration that the bullet diameters are the same. As I recall my initial research in loading manuals and catalog review lead me to the observation that 380 bullets will be under 105 grain and 9mm will be above 105 grain. There is some overlap in the middle, but you will most likely not find load data for a 147 grain used in a 380.
