380 auto. Many good brands of ammo out there.
Yup.
Yes you can. .380 auto.
No. You won't even get it to chamber.
.380 auto is about .355 and 7.65mm is .308 .
Any standard .380 ACP ammo, yes.
.380 ACP, and nothing else. Right now, there's something of a shortage on .380 ammo, and it's not the easiest to find at the moment.
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.
380 ACP, 9mm Kurz
No. 7.65x17SR is .32 ACP.
no
I am not aware of any cartridge called a 380 Winchester Special. .32 Winchester Special is a rifle cartridge, .380 ACP (.380 auto) is an automatic pistol cartridge. Either should be available from a full service gun shop.
