Gunner’s Journal has compared various .380 ACP rounds:
Sounds like the “magic bullet” thing doesn’t it? Nope! I don’t think the .380 can be made into a “stomper” caliber that can compete toe-to-toe with considerably more potent rounds, but I absolutely do believe that this load enhances its ballistic capability. To my layman mind, it appears that trying to use the “best” ammunition one can in a given caliber is a good thing, but rather than trying to make that caliber something it is not, accept its limitations, but learn to use it quickly and accurately.
