Sixgun Nut
Six of one, half a dozen of the other. Both peak with 355/360gr bullets but the .44Mag gets any bullet weight 50-100fps faster. Only if both are loaded to 50,000psi in custom five-shots or Redhawks/Super Redhawks does the .45 overtake the .44 by 100fps. Difference in meplat diameter is typically much less than the difference in bullet diameter. No critter will ever know the difference. It's purely personal preference. Less chance of odd chamber/throat dimensions in .44's.
