Calculate the amount of shot surface area that is in contact with flesh as it travels through the target. That's what causes damage. The contact area times the penetration depth.
8 .36 cal balls provide 1.62 square inches of area contacting (damaging) flesh.
16 .30 cal balls (#1 Buck) provide 2.26 si. That's 28% more area (if I did the math right) damaging tissue as it passes through the target. One third more pellet area, 32%, over 00 Buck.
00 Buck typically penetrates 20-23 inches in ballistic gel. 000 Buck would be much worse (more penetration than 00B - bad). Any penetration beyond the target is wasted and in fact increases your liability by threatening other objects/people beyond your intended target. #1B hits the FBI recommended (>12" - <17") sweet spot at about 14.5-15". The added recoil of 00/000B doesn't aid in quick followup shots either (in case of multiple a/o armored targets).
#4B sometimes makes 12" and sometimes does not while providing only a marginal area improvement of 7-8% over #1B. Any load that does not consistently provide enough penetration should not be considered for serious defensive use.
