A .380 caliber bullet can potentially penetrate a turtle shell, depending on factors such as the distance, the type of ammunition used, and the thickness of the shell. Turtle shells are made of bone and keratin, which can provide some protection, but they are not impenetrable. While a .380 is not the most powerful round available, it can still cause significant damage if it hits a turtle. However, shooting at animals is often illegal and unethical, and it's important to treat wildlife with respect.
Yup.
No. Shoot only the caliber printed on the barrel.
Do not attempt this!

No firearm exists that can shoot both 380 and 9mm. Unlike, say, the 357 magnum which can shoot 38 specials. Revolver rounds use the case rim to assure proper head space so they are more interchangeable. The 9mm and 380 are made for auto-loaders and they use the case length, rather than a rim, to determine proper head space. Because of that you can't shoot a 380 through a 9mm.
No.
No, you cannot.
Many makers offer firearms that shoot the 380 ACP.
Not recommended.
No.
NEVER SHOOT AMMUNITION IN A WEAPON NOT CHAMBERED FOR IT!!!!! Do not attempt this.
Can I shoot 380acp caliber out of my 32 pistol?
