Oh, I just found scientifical testing informatics over here
https://www.luckygunner.com/labs/self-defense-ammo-ballistic-tests/at least it gives one "bannanas to bannanas" comparison data
and re overpenetration, yes it is a fact:
From the early ?90s adoption of 16-shot 9mm pistols (Glock 19, SIG-SAUER P226 DAO, and Smith & Wesson Model 5946) through 1999, NYPD issued a full metal jacket ?hardball? round, comprising a round-nose 115 grain bullet in the mid-1100 fps velocity range.
The New York Times exposed the following facts in its startling report on the matter:
?According to statistics released by the department, 15 innocent bystanders were struck by police officers using full metal jacket bullets during 1995 and 1996, the police said. Eight were hit directly, five were hit by bullets that had passed through other people and two were hit by bullets that had passed through objects,? stated the Times.
In other words, in rough numbers, 53 percent of these tragic occurrences were apparently missed shots, while 33 percent were ?shoot-throughs? of violent felony suspects.
Counting bullets that went through objects to hit presumably unseen innocent victims (13 percent), that tells us that roughly 46 percent of these innocent bystanders were shot by over-penetrating bullets that ?pierced their backstops.?
The Times continued, ?In that same period, 44 police officers were struck by gunfire using the old ammunition: 21 were hit directly, 2 were struck by bullets that ricocheted and 17 were struck by bullets that passed through other people.?
hope this helps
or is at least entettaining
