Interesting thread on GT about bullet performance in actual shootings

[bkb0000]

Too many variables in crime related shootings. Ballistic data acquiered in such investigations are deemed invalid, due to the fact that the majority of those involved are involved in their first, and last, only shooting incident.

there's too many variables in all shootings to say that a person can shoot well enough to compensate for them. you can land multiple COM hit and still not stike anything vital. figuring in the fact that training needs to preceed experience, and that even well-trained combat veterans still aren't likely to land perfect COM hits on a majority of targets, due to all the variables and human flaw, this is even more so. more well-as-can-be-placed holes is better than bigger-but-fewer-well-as-can-be-placed holes, when we're talking about the likelihood of striking vitals.

A skilled and properly trained shooter that has reacted to actual combat, is much more efficient with all said calibers.

what's your point? and how do you support this statement?
