I'm sorry, but i can't answer this question without bringing up controversy. It all depends on the brand you buy from, what type of bullet your shooting, and what kind of target your shooting into.
In general, a .38 Special +P+ load can be more powerful than a mild .380.
380 - 357 = 23
No, the .380 has less power than the 9mm or the .45 .
It is: 380 minus 357 = 23
Yes
.380 is slightly larger in diamater than the .32, and in general, more powerful.
No.
No.
No. 38 = .357 projectiles; 380 = .355 projectiles from a shorter case
Oddly enough, both are about .35 Caliber, which is why one can fire a .38 Special round out of a .357 Magnum.the .38 Special has an actual diameter of .357 and the .380 has a diameter of .355. So the .38 special is larger and they are typically heavier than the .380 (110gr vs 90gr).
Bullet diameter on a 38 is .357; on a 380 it is .355 Case is longer on a 38.
10% of 380 is 38. 380 + 38 = 418 or 380 x 1.1 = 418
