I assume that the "nickel in the wound" refers to the cupronickel alloy formerly commonly used for auto pistol bullet jackets. Is this alloy STILL used?
It seems to me that our references to bullet jackets are pretty sloppy as to alloy names--I've seen current jacketed auto pistol bullets described as both "copper jacketed" and "brass jacketed." Can't be both at the same time. And of course we still don't know when or where those crime scene bullets were manufactured....
I've seen .32 ACP/7.65 Browning ammo that had bullet jackets of steel, too, but SUSPECT it had at least some nickel content.
It seems that "burning up the evidence," a common tactic of criminal morons, may have at least muddied up this case for the defense a little. Not sure what "reasonable doubt" means in Chile, tho.
Interesting post, for sure.
