My whole thing about caliber and bullet size is this:
Assuming everything is the same, including velocity
And also that factors such as accuracy, recoil, and the like are removed
That a larger bullet (for example, the 6.8mm over the 5.56mm) would have more energy and thus correlate to...
Ah yes, many interesting points. It makes sense to say that a lot of things besides energy impact how a bullet damages the target - but correct me if I'm wrong, certain philosophies revolving around larger bullets (due to increased size and thus increased impact) exist in the militaries of...
Oh, haha! I didn't even notice that. In retrospect, a .308 is about 160g and carries a force of 2600 joules so yes, a 200g .45 ACP does sound a bit odd.
However, this does change things significantly - the armor could fully absorb a .45 ACP. This isn't anything huge, as modern body armors are...
Thanks for the reply! I did realize though, that just because it doesn't absorb the impact doesn't mean the wearer isn't going to be protected. Absorption would help weaken the punch of the bullet, but with an excess of 6500 joules in this example, my guess is that it would punch through...
Okay so I was poking around the wiki for the video game Fallout 3 the other day when I came across this page:
http://fallout.wikia.com/wiki/T-51b_Power_Armor
It has specs on the armor (keep in mind this is mostly the type of stuff the game designers make up for interesting backstory, so...
