The heaviest bullet in my reloading manuals for the .380 is a 120 grain cast bullet.
It depends on the bullet weights. The 9 mm (AKA 9x19 mm, 9 mm Luger, or 9 mm Parabellum) is faster than the .380 ACP (AKA 9 mm Kurz) except when you compare the lightest .380 bullets to the heaviest 9 mm bullets. If you compare the same bullet weights in each, the 9 mm is always faster.
the most common weights are 90 and 95 grains, but they are available in other grains. I think 105 is the heaviest available.
how far does 380 bullet travel
380 and 9mm ammunition IS NOT INTERCHANGEABLE.
.355
No, the bullet will not seat.
360 mph
.355 inches.
9x17mm, otherwise known as the .380 ACP.
No. A .32 bullet is about 7.65mm, and a .380 is 9mm. It is too big to chamber.
The .380 is a 9mm bullet. But, going with the assuming that you're comparing the .380 ACP (9x17mm) against the 9mm Luger/9mm Parabellum (9x19mm), the answer would be no.
