You can't- that's impossible!
No. Ammo designated as .38 or .38 special is different than ammo designated as .380. .380 is designed for semi-auto handguns and .38 ammo is for revolvers.More to the point, the .38 Special has a longer case, and a larger diameter projectile. The .38 special bullet measures .357" diameter, the .380 measures .355" diameter. The .38 special is a 'rimmed' cartridge, and the .380 is 'rimless'. Luckily, .38 Special ammo will not fit in a .380 magazine, otherwise the results could be disastrous, possibly turning your .380 handgun into a hand grenade.
It depends on a couple of factors, but in general, a 9mm is louder because it's a higher pressure cartridge than the .380.
It depends upon the firing angle, among other factors. For a 95 gr .380 ACP moving 955 fps, it will travel about 1423 yards (80% of a mile) when fired at an optimal elevation angle of about 30 degrees.

.380 ACP is 9x17mm, while the 9mm Parabellum/Luger is 9x19mm. Additionally, the 9x19 uses heavier projectiles, and also generates higher chamber pressure, necessitating a locked breech pistol, whereas most .380/9x17 pistols use an unlocked breech.
