This is a discussion on Another .380 bullet thread within the Reloading forums, part of the Defensive Ammunition & Ballistics category; I am new to reloading, and will be ordering .380 bullets. It appears that they are the same diameter as 9mm. Are they interchangeable? Thanks ...

What does your loading manual call for? I have some recipes for 115 and 124 fmj in 380 using hp38. They are in the 2007 printing of the Lee manual.

You are correct about the weight. I compared the components of one round using the 9mm bullet to a standard .380 round and the difference was about 25 grains. I will do more research before continuing. Thanks guys.
Yes they are the same diameter. The problem is that as you get into a heavier bullet, the length of it may budge the case of the .380 and take up a lot of the volume where the powder is. The heaviest load I have seen for 380 is 115 grain bullets. Average load is around 90 grain bullets.
