I always ask. Not to poke with a sharp stick, just asking...….what got shot?
@Michael458 has killed many hundreds of living things. My Pal will drive you to distraction with field autopsy results. He then came home and over the period of a year finally devised a "trap" that gave him the Exact results he found in the field autopsies. Thin skinned to massively thick skinned animals with bone and muscle to deal with and then recheck the "trap".
The single thing Gelatin can do is give the same medium for all involved.
That said...Clint says 85% of all People shot with a handgun survive. 85% of all People shot with a rifle Die.....
That said my mentor Jeff Cooper had Nothing good to say about the .223. That's where we parted on this issue. My information was Irrefutable!!! 13 One shot kills from the trunk of an old Impala by a single teenager with basically No training in the DC area a few years back.
You start introducing any caliber projectile at 2,500 FPS to a human's chest area..assume he's gonna take it Bad.
