Oh....

Are you saying that you built a round of handloaded "9mm" but you constructed this in a .380 Auto cartridge case?

That would be -FAR- more dangerous simply because you are putting the components designed around the 9mm in to a smaller case with a smaller space for combustion. All else being equal, you RAISED pressures in this situation, if you actually succeeded in doing this.

How much? Couldn't tell you. Someone with the Quickload software could make a mathematical estimate.

Best way to find out if your tooling would have pulled off this reckless stunt is to attempt to repeat the construction of the round willfully.
