In order to take all the personnal prejudice out of the discussion, these are two quotes from "Metallic Cartridge Reloading" 3rd edition:
10 mm page 307: " Useable case capacity ... is about 14.6 grains of water."
41 mag page 310: "Useable case capacity ... is about 20.8 grains of water."
There is no possible way the 10mm is the ballistic equivalent of the 41 mag. Actual chronographed velocities from a 4" ported Taurus Titanium Tracker:
Federal 250 grain factory Cast Core 1055 fps
maximum handload 250 grain WFLNGC Cast Performance 1265 fps.
Weight of Titanium Tracker with Hogue Monogrip 25 ounces. I replaced the factory Ribber grip because while "cushiony", they need an adapter behind the trigger guard and it beats the index finger of my right hand unmercifully. Taurus firearms have a deseved reputation for poor quality and their customer service is not poor it is non exsistent. I lucked out and got a revolver with no issues. It is not a S&W but no other manufacturer makes a 5 shot 41 mag on an L frame.
When discussing the 10mm vs.the 41 Mag they are not equal ballistically but the real question is do you need the extra power? Where I wander in the back of beyond I need the incremental increase.
