I will say this, from my observations, I elect to use the .44 caliber Remington Semi-Jacketed Hollow Point bullet as my personal defense selection.
I have observed its effect on animate tissue loaded in the .44 Magnum. So, I elect to use it in my .44 Special. Until I'm proved wrong in actual practice, this will be my choice for daily carry.
If a fella takes a round designed to work well for the velocities of the 44 Magnum and loads them to the velocities of the 44 Spl. the bullet may not work as well or as intended. What will expand at 1300 fps likely will not expand at 900. It may be useful to experiment some.
