That would be 38cal. ammo
NO
It depends on what you mean. A .38 revolver may be a .38 special, but there are other types of .38 besides just the special round.
No, you cannot. The .38 Special can be fired out of .357 Magnum revolver (but not automatics or lever action rifles), however.
Only if it's a .22 Long Rifle revolver. It's not compatible with the .22 Winchester Magnum Rimfire.
I'm not aware of a .45 Magnum. There is a .44 Magnum. The 44 magnum is typically a revolver round, very high power. The 45 ACP is typically used in semi-automatic pistols. The 45 ACP is not as powerful compared to the 44 magnum (mostly due to the amount of propellant in the 44 magnum compared to the 45 acp).
It's the round which makes the difference, not the pistol. A .45 automatic pistol is going to be more powerful than a .38 revolver, for example. There are revolvers chambered in cartridges such as the .454 Casull and .500 S&W Magnum, which aren't available in any automatic pistols, but it's still ultimately the round which matters, and not whether it's an automatic or revolver.
consider it`s a rimless round that`s going to want to drop deep in the chamber and won`t reliably fire in any case. If and when you do get a fire the bullet is smaller than expected in any .38 or .357 revolver so accuracy will be bad and the cases will split because they don`t fit properly, Besides super .38 Auto cartridges are more expensive
Yes
They are different cartridges based on dimensions; however, the 38 and 357 can be used interchangeably in a 357 revolver. This is good because of the 38's lesser kick and greater affordability for practice. IMPORTANT: You can use a 38 round in a 357 revolver because the frame's built to handle the 357's greater strength. Do NOT fire the stronger 357 round from a revolver built for the lesser 38.
No- it is a better handgun round.
no the magnum round is only for revolvers the correct round to use would be the .357 sig
It is the round with which the revolver was "proof fired" at the factory to test its functionality.
