What is the difference between .41 magnum and .41 Remington magnum?
Can you shoot the .41 Remington Magnum ammo in a handgun chambered for .41 Magnum?
Remington is just maker brand.
There is no difference between the two. The .41 Remington Magnum is the same center fire firearms cartridge as the .41 magnum; Remington is just the name of the manufacturer. See en.wikipedia.org/wiki/.41_Remington_Magnum for details.
