guns and ammunition vary greatly in power . obviously if there are 2 objects same weight hitting a head the one going 3 times faster will be more lethal. the more energy put on the head the more likely to be deadly. this shows rifles have much more energy than handguns . there is one hand gun not shown that is powerful the .460 magnum smith and wesson. a professional pitcher pitching a baseball can kill someone hitting them in the head as the baseball can travel 90 mph. that is only 87 foot pounds a 9mm handgun shown below is 362 foot pounds so very likely if aimed right and don't flinch before shot. but i would like to go with the 3548 foot pounds of energy win mag why now 3548 vs 87 i think it's very high probability.
if you throw a hard object at a human dead it's the energy that will make it fatal. for example a baseball or a bullet travelling faster will hit the head with more energy and be more lethal. a pro pitcher can pitch a baseball around 90 mph and that can kill a human fracture skull if hit on the head. intuitively we see if the base ball were flunng slower speed the energy and lethality would be less. a baseball at 90 mph 144 kilometers per hour will expend 87 foot pounds of energy which can be lethal . one can acquire guns that can produce 2000 foot pounds so 87 vs 2000 yes the most powerful guns and ammo will be lethal if the aim is good and don't flinch before shot if i hit my head.
the average handguns can have around 400 foot pounds of energy with a contact shot as much self inflicted are.
the most powerful handguns
the most powerfull shotguns and slugs around 3000 foot pounds
rifles can vary from 2000 foot pounds to 4000 foot pounds .
in addition a contact shot will shoot hot gasses into the brain kiling it if the aim is good and the gun and head are held still no flinching before the shot only moving the trigger and trigger finger ( this can be perfected with enough daily correct practice dry firing).
