>Glad we cleared that up.
Likewise, otherwise that would have been a tremendous issue. Looks like RMA still takes the cake for the most cooked plates.
>Yeah, that looks like one hell of a slug.
I think it's an analogue to the "post-7N37" stuff the Ukrainian firm Stiletto Systems came up with years ago. They had a 14-gram 7.62x54R BS14 (216gr) long-core design. I don't think there's really too much 7N37-capable "XSAPI++" personal armor out there, I think it's more "kill ESAPI / Level IV and vic armor but with even more standoff than 7N37 can."
>9mm PBP exists specifically because PP2000 was a PDW project in the vein of P90 and MP7
True. 7N31M goes one step further though. Take the steel-core 7N31 (PBP) and give it a VK8 alloy tungsten core like 7N39 / 7N37. https://vpk.name/news/414241_tulskii_broneboinyi.html
It's likely capable of defeating NIJ Level III / RF1 plates made entirely out of UHMWPE even at handgun velocity.
>LIBA
The company that developed it in particular is a Mofet Etzion. The tech was licensed to Tencate and they were flipping "20-hit" M993 rated LIBA plates by 2000. GEN2 LIBA adds an Armox steel intermediate layer so M855 / 7N24 can't sneak between ceramic pellets, but that adds a huge weight penalty. They're tanks though and can withstand dozens of hits. The tech has a lot more utility for shields at that rate than body armor, because if you're eating that many hits to the plate you're eating a lot more elsewhere.
>Well, yeah, it's not really supposed to defeat Br5 or equivalent armor
Funny thing is that a few 5.56 AP loads hype themselves on being able to defeat NIJ Level IV or ESAPI (latter is easier if it's pre-REV. G due to the boron carbide amorphization problem - M995 @ 3,350ft/s is a known ESAPI A-F killer).
>similarly enlarging the penetrator
I liken 7N39 to being the 5.45 equivalent to Nammo AP4 or DM31 5.56 AP. There is room for an AP45 counterpart.

What's your take on .338 7N45?
