I doubt that a hot loaded 7.62x25 from a submachine would do that. That load must be the excaliber of all .380 ammo.
Below is what they call their standard pressure .380 load penetrating gel plus packages of ribs that is not bad
That's my video. I put in the notes that the first shot actually bounced out between the rear blue jean/meat pack and the gel. You can see it if you watch for it. But, all three rounds impacted the rear pack, as you can see from the momentum from the video. The first round definitely damaged the rib in the back. It really doesn't detract from what the round did.
Prior to getting my hands on the gel block, I did two other prior tests, the first with water jugs and second with water jugs and meat packs.
In the water jug test, the round got went through 7 water jugs and got captured in the 8th. The round appears to have dropped low enough to skid along or bounce off the table and deflect back up.
In the mixed media test, the round went through a front meat pack but missed the bone. It exited the third jug and hit the meat pack on the rear. Because I already had shot that meat pack, I thought that the bullet had done no damage. But, after further inspection, I could see that it caused damage to the rear meat pack and bone.
I see no need to use a +P version of this ammo. The standard pressure version chronographs at 958 fps out of my gun with an extreme spread of 31 fps over 8 shots. I do keep this round in the gun when I am at the cabin. I occasionally slip it in my pocket when I go outside and don't feel like putting on a bigger gun. (On pavement I use 90 gr. (versus BB 100 gr.) standard pressure Lehigh Xtreme Penetrators at the same velocity, but that is another story.)
