Yes. The 44 magnum can fire 44 special ammo in the same way a .357 magnum can use .38 Special.
A 44 magnum is just the new and improved version of the 44 special which the special is a 44 caliber. Magnum just means bigger so the 44 magnum is pretty much in between 44 and 45 cal. However, if you mean size, .45 is slightly larger in diamater than .44.
No. The 44 Magnum cartridge is too long to fit a .44 Special firearm- and it is loaded much hotter than the .44 Special- unsafe to attempt. .44 Special CAN be safely fired from a .44 Magnum firearm, but not vice versa.
In a .44 Magnum revolver, yes. In a semi-automatic .44 Magnum (such as the Desert Eagle), no.
It can use either 44 magnum or 44 special
The 44 Magnum case is a little longer.
Projectile diameter.
Bullet diameter, case length.
38 special is only a revolver caliber. that's like saying a 44 magnum revolver or a 500 special revolver. a revolver is a revolver
44 magnum and 44 special.
44 special and 44 magnum only
None of my references show a .44 Special Blackhawk- 44 Magnum yes, 44 Special, no. The .44 Magnum Blackhawk is about $450-550, depending on condition. The FLATOP version is worth significantly more.
