This is very complicated and depends mostly on the barrel lengths of the pistols and the specific loadings of ammunition which are being compared.
It is possible to buy or handload ammunition such that either of these are more powerful than the other or that they are the same. However, it is possible to load .38 special with heavier projectiles than a typical .380 auto load and stay within safe loading perameters.
Understand that total energy is a function of projectile weight and velocity. Lighter projectiles with the same charge of gunpowder will likely have much higher velocity than a heavier projectile.
Not really. The .38 usually refers to a rimmed revolver cartridge, such as .38 S&W, or .38 Special. The.380 is an automatic pistol cartridge, and much shorter.
No, i asume you dont have see .380 pistol and a revolver 38 spl, the .380 and 38 spl ammo share de same diameter boot no the longer, the 38 is for a 38 special revolver tipe and the .380 is for an automatic pistol tipe some people call 9mm short.
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.
One would think that .380 ACP and .38 Special would be the same size--namely 38-hundredths of an inch. But there can be some flexibility in stated caliber and actual caliber. Long story short, .380 ACP is the same diameter as a 9mm, roughly .355 caliber. .38 Special is basically .357 caliber.
There can easily be confusion between the names of three cartridges: .38 auto, .380 auto, and .38 special. .38 auto is an antique and obsolete cartridge replaced by the .380 auto. This is why there is an extra zero on the end of the name and it's called "three-eighty." Neither cartridges have a full rim and are intended for semiautomatic pistols. .38 special is a fully rimmed cartridge intended for revolvers.
No.
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).
The 38 special will be in a revolver and the 380 ACP most probably a semi-auto. However some of the energy of the bullet is used to eject and reload the 380 which dampens the recoil a bit. Also the .38 special is actually 0.357 " diam and the 380 is 0.355". The upshot of it all is that the .38 would have more recoil.
No. 38 = .357 projectiles; 380 = .355 projectiles from a shorter case
No.
In general, a .38 Special +P+ load can be more powerful than a mild .380.
Question is too broad to answer. In general, use ammunition that is the same as the caliber or gauge marked on the firearm. If it is marked .38 Special, use only .38 Special- NOT .38 S&W, NOT .380. NOT .38 Super.
