>Or it could be some chairborne fuddlore, there's a lot of that kicking around guns.ru forums.
True, but the Russian MIC isn't exactly transparent and it's feasible given the circumstances they would try to keep 7N37M a secret. Word of 7N37 spread like wildfire among Ukraine in 2014 - courtesy of cartridge collectors like wolfgangross and Ukrainian media. This ended up giving it a propaganda effect, so 7N37 itself has this sort of "legend" that I don't think any other AP load ever had - besides meme fuddlore like KTWs and the erroneous media scare around Black Talons. It's feasible plates rated to beat 7N37 do exist, after all it's been more than a decade, so if there's a killer beyond that level I'd keep it secret.
>Again, first time I'm hearing about it. Some proofs plz?
Sure thing, see pic related for a cutaway.
>Sadly, that's more foresight that I can credibly ascribe to Shoigu-era MoD
True, but it's an easy sell. I mean, if tungsten-core 9x19mm 7N31M is a thing, why not an improved 7N37?
>No, not really. Relaxed weight limits + multi-hit demand is a radically different set of constraints.
I was more referencing materials. The Israelis developed a technology called "LIBA" (Light Improved Ballistic Armor) that's basically ceramic pellets encased in a composite matrix with a PE backer. It comes in both Aluminum Oxide and SiC versions. It was first developed for body armor purposes in '98 but wound up armoring vehicles like US Strykers. Multi-hit capacity is extreme (15+ for a 10x12 Level IV) and weight isn't too punishing, but it has a slight "gap" problem between pellets in the OG versions.
>as is usual in solo plate tests. Pic related.
I see one plate ate quite a few 5.45x39 7N39 (your pic, upper left). I'm seeing a lot of plates actually handle that one just fine. You think it's a core mass problem or is it just not designed to handle BR5?

On dirt bikes or golf carts?

I agree completely. I think you can break rounds into four camps.
1. The garden variety, composed of everything from pistol ammo to M855 / M193, then M855A1 to M80A1, M61, B-32, M2AP. Rounds that can pierce certain varieties of armor but comfortably all fall within the proxy envelope of NIJ RF3 / Level IV.
2. The brute-forcers. Rounds that brute force their way through armor by virtue of just being fuckheug. .50 BMG and 12.7x108 / 14.5x114. Even in non-AP versions these rounds can produce excessive behind-armor-blunt-trauma and beat plates that aren't up to par.
3. The less-garden variety. Entry level tungsten core AP. M993, Swiss P AP, 5.56 M995 and AP4. These can be handled by a higher rung of plates, like either XSAPI or Colossus or LTC 28601, etc.
4. The next-gen, composed of the real nasty threats like 7N37, M1158, XM1184, SmKH, 7N37M, 7N51 (pic rel), then the harder .338 APs like AP529, API526, M1154 (M1158's big bro), M1214 mini-Raufoss, and the rumored 7N45. M948 falls kinda half into this camp, half into camp #2, but the Swedish SLAP (PTR 10 PRICK) is firmly camp #4.
You can have plates in camp #2 that lose to camp #3-4 threats. You can have plates in camps #3-4 that lose to camp #2 because of how the relationship between strike face and backer works with modern ceramics. The old Ceradyne .50 cal plates can handle .50 BMG M33 at a certain velocity, probably a lot better than a FORT ACP-M can, but I wouldn't trust those boron carbide / fiberglass Ceradynes to not amorphize against 7N37 and other WC-core penetrators. You need a stronger strike face to handle tougher cores, but you need more backer to control resulting fragments and minimize BFD / resulting BABT.
