ok. so i was looking threw a few of the ol reloading books. and i noticed that some of the 9mm and the 380 bullets share some of the same diameters. and i just got a box of hornady tsx's for my 9mm that are .355 and the wife has a 380 as a ccw and in the book it says to use .355 projectiles for her gun. so i was wondering if i could use them in her gun also? i know they call the .380 the 9mm short or 9mm corto. i was just wondering if the similarities are close enough to do this.
