7.62x39 v. 7.62x51 short range wounding differences

[Bcwitt]

The OPs question specified " Human adversaries" who exactly is that?

Against rifle rate body armor neither 7.62 Nato, x39, or 5.56 is really going to make a difference. None are going to penetrate.

There are multiple scenarios where a US citizen could possibly need to defend themselves at extended distances. Especially if someone owns decent amounts of property.

Bad guys, ie, people shooting at me. Its an unlikely scenario, but not an impossible scenario.

I don't know what the OP is planning, and I regret contributing to this fanboy conversation. I wonder if a DA would look at posts to show intent. And the rest of us for aiding and abetting.

Right. Not impossible. Do not assume they are not well equiped.

Depends largely on what type of armor. Russian infantry armor cannot take 762x51.

Ballot has been on this forum for a long time. He posts discussion provoking hypotheticals pretty often. With the adoption/testing of the XM7 currently, discussions of the battle rifle vs the assault rifle are happening all over the internet.

I am not planning anything, and don't see there was a need for the accusation. I was asking about the terminal ballistics of 2 cartridges specifically at shorter ranges than are generally discussed for rifle cartridges. If this is an inappropriate topic, I am happy for a moderator to delete the thread. I wasn't trying to cause a ruckus.

I didn't really think you were but the though occurred to me that we don't know who we are helping and what they plan. I thought that point should be raised. Also I think your trolling because you and the fanboys clearly think the cartridges are equivalent. I suppose for your discussion the differences are minimized. The problem with imaginary scenarios, real life can be more complicated and have nasty surprises.

I hadn't noticed but thanks for the info.

I guess at this point a 300 WinMag is the same as 7.62x39 under 150 yards.

(4)7.62 x39 on 3/8 steel plate at 50 yards and one 308 nato thru and through. 44 mag divit..

I don’t think they are equivalent. My question is at what point does the difference become significant.

It's unfortunate that you've been accused of having a nefarious motive in asking the question(s) that you've asked when that's clearly not the case. I hope that you'll continue to pose interesting questions here in the future because they provide an opportunity to inform those who might not ask.

Well, cardboard is notorious for not stopping bullets. I suppose the OP poses the hypothetical however he chooses, but in the real world I don't think we can make a blanket assumption that the opponent will be unarmored in a world where ceramic/PE Level IV plates can often be had for a hundred bucks.

 

[d2wing]

Well, I am out of popcorn, LOL. DO you contemplate, civilian weapons and ammo, or military based and FMJ? Or are we done?

That’s not entirely true. Russian military contractors make composite armor now. Cardboard glued to pot metal. That way it is heavy enough. Contractors are paid by the pound and cardboard is too light to scam the defense ministry that much! Plus, when you’re outfitting a chain smoking, tuberculosis-ridden, serial arsonist fresh out of a prison, you don’t want him to be too mobile.
