Hello again,
The Pietta .36 cal. pepper box loaded with thirty ( 30 ) grains of 3f powder and a double patched .350 ball would be terrible medicine on any would be mugger.
It would also outclass any .44 ball, as far as damage.

I would still like to see this quantified.
From what little ballistics gel testing we have shows a ball from a belt revolver barely produces a caliber sized hole. It's slightly better than what we see with today's FMJ bullets. And this is with a standard length barrel.
According to my 2nd edition Lyman Handbook is shows a .36 Navy with a .375" ball over 30 grns of Pyrodex P (the most energetic powder tested) it achieves 942 fps with 156 ft/lbs of energy. A .44 cal revolver with a .451" ball and 35 grns (not exactly a full chamber) of P achieves 979 fps and 294 ft/lbs.
The Pietta pepperbox cylinder, according to DGW, is but 3" long with about 1/3 of it hanging beyond what was the cylinder of a standard Navy sized cylinder. 1" of barrel isn't sufficient to get much velocity and wouldn't even completely burn up a typical full charge (~30 grns of 3F).

Excluding a CNS shot the .44 ball would be more effective producing a larger permanent wound cavity. Of course an excellent shot, such as the one placed through Tutt, is quite effective and likely would have been even were it a .31 (but a good bit closer). A lung shot may or may not take a man eventually. And then again maybe not as I have had a pneumothorax (collapsed lung) twice and flabbergasted the doctors by my ability to behave normally (walk and talk) with most people requiring a wheelchair and barely whispering.
Of course all of this is dependent on the determination of the attacker, as well as their understanding and feeling from being shot.
Outside of a HP bullet there's not much else known to be as devastating as a wide meplat such as this:
That's a .457" cast ball with my 195 grn WFN bullet that's .460" long so as not to eat up precious powder capacity as well as assuming my Pietta NMA was coming with a slow 1:30" twist. On the right is my 170 grn version that's .400" long. My NMA loves both of these and shoots them equally as well as the ball with ~33 grns (weighed) 3F Olde E producing .45 ACP performance according to similar test results. This is its most accurate charge tested from 25 grns up.
The far left bullet is a modified version weighing 285 grns that I had Accurate Molds create for my ROA knowing it could easily accept the additional pressures created by the weight and longer bearing surfaces and is the infamous bullet Richard Eames enjoys bringing up as someone I sent bullets to decided to try it in his Walker over 52 grns of Pyrodex P which blew the chamber wide open.
