.45 Colt mostly because it does the same thing as a .44 Magnum at less pressure, about 10kpsi less when both are loaded to the max.
One of the gun world's oft repeated old wives' tales. Newton's 3rd Law also has an issue with it.
Perhaps you don't understand Newton's third law. The 45 has 10% more area over which that pressure is acting, and hence at the same pressure as the 44, the 45 is going to have a greater reaction. Conversely, the 45 requires less pressure than the 44 to achieve the same velocity, a proper application of physics not some old wives tale.

I got banned on another web site for a debate that happened on this site. That's a first
