penetration

Here are some non-standard rounds taking-on body armor. This is for some fun viewing. Could be informative. I enjoyed these videos and thus wish to share. When I head to the range it is for sighting-in; then, I wish to have some fun. The second video ends with a small cannon taking-on body...

This may have been posted before, but I think it is interesting evidence for how much cover a normative commuter car may provide in the face of gunfire. Even non-gun owners may find this interesting. I know most on here already know these facts, especially military or police. But I think a lot...

Recently got ahold of a little Lorcin L25 which made me interested in doing some real world comparisons. The first is below. I have a lot of interesting material available to me at work as waste material, today I made up a small 4"x6" 30 layer UHMWPE armor panel. A very sloppy panel, but...

Thought this was the most understandable, fair and real world test I've seen and will surely start no controversy by settling that age old question once and for all time:

For non-central nervous system hits incapacitation is largely caused by a quick drop in blood pressure. Hitting the heart does that quickly. For other areas the blood pressure drop will take a bit of time. Exit wounds seem to be advantageous as it would make two paths for the blood to exit the...

At the risk of starting a 9mm vs. 40cal debate (which I'm really hoping to avoid), is there enough data to suggest that 40cal FMJ is a better defensive round than JHP? This can also be spun as an expansion vs. penetration question. FMJ has the penetration of 18+ inches, but lacks the...

Are there any gel tests out there that show how deep an unexpanded 9mm Hollow Point will go? Not like the "partially clogged" hollow points in denim tests, but either fully unexpanded (no expansion at all) or bare minimum expansion. I feel this would accurately depict what HP's might do once...

What makes the MacPherson/Schwartz formula so accurate? Also, I was curious if anyone could be a BIG help to me, by doing the MacPherson/Schwartz Penetration Formula for a 147 Grain FMJ @ 908 FPS (9mm American Eagle Flat Point FMJ-AE9FP). I've scoured the internet and just can't find it. Thanks.

Hi guys, I had a quick question. I was studying the FBI Protocol when it comes to the 10% Ballistic Gel penetration standards, and after digging through multiple websites, I noticed that certain aspects aren't talked about as much, like skin resistance. Do you all no how many inches of gel is...

I know that the FBI Standard for adequate self defense ammo 12-18" of penetration in properly prepared 10% ballistics gel. And from my research, the vast majority of JHP's fall into the 12-14.5" range. I also know that penetration in gel is not the same as in a body, being that I've read that...

Specifically the 38 caliber 140 grain penetrator. But I'd also like to hear any Lehigh info regarding game, such as animal, bullet, velocity, pentration, DRT, etc. I've hunted exclusively with 45 colt in Rugers and Smiths. Bullet weights from 255 to 335 grains. Bullet styles Keith, LBT and...

Over penetration might get you sued, but under penetration might get you killed.
