Better at wearing out bolts and barrels, sure. It has slightly better capacity to go through cover(but not enough to make it an AP round), and even worse ballistics than the M855. So in essence, they took what made M855 a shit round and made it even worse, good job DoD. Barrels and bolts wear out half again as fast with M855A1, thanks to near-proof chamber pressure. Oh yeah, and until they designed a special snowflake magazine just for M855A1, it was gouging up barrel extensions.
>seems to be more accurate
Accuracy specs are the exact same as M855, and real-world testing confirms that. The "more accurate" groups were done on AMU match-grade rifles, and compared to M855 shot out of bog-standard grunt M4s. But even though accuracy is the same, POI isn't, so after switching to M855A1 the whole unit has to re-zero. What fun!
It's a shit round. Just an expensive, slightly modernized version of M855 (which is also a shit round) designed to adhere to King Nigger-era training regulations with muh lead-free round.

They've got nine. Level 4 russian armor is made to stop 7N10 5.45x39mm armor piercing ammunition, fired from an AK-74. So the thread is still stupid since it's the armor is made to stop bullets with steel penetrators. I couldn't find the type of steel used for M855A1 though, other than it being "high strength steel".

Russian armor standards are weird. Class 1 can stop 9x18 makarov Steel penetrator so probably 9mm HP or even FMJ as well. Level 2 can stop 7.62x25 tokarev and so seems to be stronger than 3a that cannot. 2A can stop 12 gauge so it's probably worse than level 1. Level 3 stops AKM or AK74 steel cores so its basically lvl3 NIJ. Level 4 is like level 3 but stops new standard issued 5.45x39"high penetration" with hardened steel core. Beyond that they go with 7.62x54r, same but AP, 7.62x39AP/API etc. There are several different classes that are differentiated only by stopping API rounds and i dunno if one class includes another as lvl 6 stops x54r AP and lvl6A stops x54r API, which one is stronger who the fuck knows.
That's old classification, though.
The new one is a bit simpler but there's less info on that.
Basically:
Lvl 1 - steel core makarov, it's a bit higher than lvl I NIJ
Lvl 2 - 9x19 +p Russian load, FMJ, nearly lvl II NIJ, they probably copied that
Lvl 3 - stops 9x19 AP vodoo magic(albeit older one - 7N21, 7N31 will go through), it's your IIIA NIJ(that one can actually stop the 9mm AP too, surptisingly)
lvl 4 - 5.45/7.62x39mm AP, basically lvl III NIJ
lvl 5 - 7.62x54r AP(all types), basically lvl IV NIJ
lvl 6 - stops 12.7x108mm API(basically .50 BMG from warsaw pact), the only purpose is to show off, i suppose.
There seems to be a trend in Russian army to copy US designs and decisions, probably they don't want to fund their own research or whatever.

M885A1 is the best round design from terminal performance against humanoids point of view ever. It fragments down to at least 1900 FPS has no fleet yaw issues at all, starts fragmenting only after 1 of travel in flesh with 20+ of max penetration and has respectable for non tungsten AP intermediate caliber penetration penetration (goes through level UHMWPE and steel level III plates).

>M885A1 is the best round design from terminal performance against humanoids point of view ever
Every test done by someone who isn't an Army or DoD shill suggests otherwise. M855A1 does even worse on soft targets than M855, which already does pretty badly. The only advantage A1 has is more barrier penetration, but it's still not high enough to qualify as "armor piercing" so who gives a fuck. And the only reason it has that is because M855A1 is loaded to higher than chamber spec and wears out bolts and barrels really fucking fast. If you put that much powder behind a non-retarded bullet it would show similar performance to your overpriced memeround.

Well, the official version is that the round was designed for longer barrels and not very fitted for pistols, causing great muzzle flash, overpenetration and insufficient stopping power. The unofficial one and the one that i think is the main reason to change rounds at all regardless of choice is gun control - tokarev rounds were basically everywhere after the war, as well as guns for them so any population disarming attempt wouldn't work well. They could also choose 9x18 due to their calculated "stopping power" that might have been faked for aforementioned purpose or the need for a more compact police weapon for peaceful time, though the main reason would remain the same. Never trust leftist scum, never rely on their empty promises and never offer them help.

Making the barrel extension out of something like D2 tool steel like those high end AR15 bolts would make them hold up just fine. Hammer forged barrels are already work hardened due to the manufacturing process so they already will last, if they wanted to have an even harder barrel surface then they could make them out of more expensive materials like the barrel extension.
Guns are made by the lowest bidder from the cheapest material that is sufficient, paying more quickly gets you a vastly superior firearm.

>>629107
>For example, it's not necessarily so that the steel having twice the tensile strength means that it actually will last twice as long.
The life expectancy of parts such as the bolt in an AR15 is effected by material strength and hardness. Part wear can be thought of as two different processes, one in which load cycling slowly causes the part to fail and the other where the metal is slowly worn away. Material strength effects the first one since the load cycling comes down to how close you get to the materials yield strength each time you load it, if your material is stronger then the yield point is higher and so less wear will occur each time you load cycle it. Material hardness is as the name implies how hard the surface of the material is and by extension its resistance to being scratched, if you have a part such as the feed ramps on a barrel extension being exposed to a hardened steel penetrator then the one made of the harder material will not wear down as easily (if the difference in hardness is enough it won't wear down at all) which is whats relevant to the thread.
In terms of verified reliability, standard AR15 bolts were designed and are built with a safety factor in mind but even after significant use the lugs can still crack and fall off, the infamous AR15 filthy 14 which was run for something like 30,000 rounds with minimal cleaning actually broke two bolt lugs at around 16,500 rounds.

M855A1 was specifically chosen because it is a POG and JSOC wet dream because it can go through steel WWII helmets at 1000 yards, is "green" (ie low lead) because only a west point graduate could think elemental lead was damaging to the environment, and is basically match grade which triples the price per round.
As to why they wanted it to penetrate a WWII helmet… See, Russians kept the same steel shell of a helmet from WWII, but they continued to add improvements inside the helmet which weren't visible from the outside observer. For example their 90s helmet had an aramid fiber liner that was light years ahead of Kevlar. But the superficial resemblance meant retarded Pentagon brats thought Russians were using pure steel helmets about 1/16th of an inch thick, which is why M855A1 had that requirement, and why 5.56 ball was rejected.
Unfortunately a steel bullet has less mass and less momentum than a lead bullet, which means it has less effect on soft target. It's also ridiculously expensive considering it can't penetrate the armor of any of Americas superstate rivals.

It isn't match grade, and it doesn't triple the price. It's a few cents more, if that, and seems to be doing just fine. In fact, for a while it was causing problems because it was going through the walls on shoot houses. Seems like a job well done to me.

Yaw is a myth, 55 grain ball killed because it fragmented. Not magical tumbling or minor yawing, because the fucking bullet fragmented so quickly, so violently it acted more like a soft point or hollow point than any FMJ, or any bullet meant for the Hague. Yaw was named as the culprit because some Hague Convention followers didn't like the idea of a bullet that fragmented in flesh and might violate the Convention. Also 55 grain ball sucked fucking dick for penetrating ANYTHING, much less armor of any type. Again, the helmet thing was another excuse, not the real reason. Fragmenting high velocity ball might damage a person, but the same fragile projectile that fragmented in people has a nasty tendency to fragment in pretty much everything else. In combat, barrier penetration is important, so at some point the military wanted a bullet that didn't blow up into a bajillion pieces when it hit any barrier instead of punching through and hitting the guy behind it.
Decrease lethality, yes. Increased barrier penetration, yes. It was a major tradeoff, but it satisfied the humanitarians as well as finding a bullet that could pierce more cover reliably. Green tip may ice pick (nothing to do with barrel twist, 55 grains didn't yaw and tumble they fragmented, 62 grainers stick together and don't fragment in flesh) but it also reaches out and touches.
>the new super projectiles are designed to pierce Eurasian hard armor on people
Bullshit. Like the helmet excuse for green tips, this is a misnomer, and excuse. The entire point of this new round is to keep the barrier penetration of the 62 green tips and hopefully magically add the fragmenting properties of 55 grainers somehow at the same time and get the best of both worlds. Wither they can pull it off as effectively as they claim is another issue entirely.
In overall, its one of that fatal flaws of 5.56/223 is that any bullet really good at tissue destruction will be very poor at barrier penetration, any bullet good at barrier penetration will be poor at tissue damage. This new bullet is trying to save 5.56/223's ass from yet another legitimate criticism's of its shortcomings. (The wonder kids got greedy and picked the smallest cartridge they thought they could get away with. The British were right all along with .270-280 and 224 is simply too small for universal ball applications)

Well known problem with armor piercing for a very long time is that increased velocity will often times decrease penetration. At some point the higher velocity causes the bullet to fail, too much stress and dynamics, the physics are all there to cause the bullet to simply shatter, fragment, fail. At some point many rounds have a perfect optimum velocity for penetration, maximum velocity without going over the brink.
This was the cap of standard anti tank high carbon steel armor piercing rounds back in the day. Hyper velocity anti tank rounds didn't come about until they could make tungsten or other hard core material that could withstand impacts at higher velocities without shattering like glass. This meant that standard steel projectiles basically had a velocity ceiling that limited the effectiveness of a caliber, either make a heavier projectile for caliber or build a bigger gun.
Without the right material and build, sometimes faster is worse.

Modern tank APFSDS are made from tungsten/DU alloya that have tensile strength and elongation than best steels. And they work differently, long rods are eroding penetrators and destroy themselves during penetration. Its just who ends first armor or rod.

KEP development was short term, in a matter of mere years all the major powers had KEP for their front-line armor during the Second World War, keeping a near parallel pace with RHA development. Tungsten has been a strategic resource since before World War One, primarily in mining and high-heat applications, but it's used in KEP development began with the Germans in their Anti-Air shell development, and was swiftly adopted into use in armor by the Brits (APCR) and US (HVAP), with development of the APDS by the Brits debuting in 1943.
>>629441
Well, for APFSDS is a bit more complicated. Long rod are more recent development and armor thickness has it limitations (in reference to RHA), which is why development in ERA and APS is on the rise, but with that comes segmented long rod penetrators. What makes armors like Dorchester and Chobham so special is their similar function to SAPI carbide based composite plates, as they plates are struck, the composite shatters, causing it to become denser and denser, making penetration a near impossibility as the shatter composite simply absorbs the kinetic energy of the penetrator, cause it to stick in the armor like an arrow.

It's using a different powder and while chamber pressures are higher, they are not as high as has been claimed ITT and others. Yes, it's a longer bullet, seated deeper in the case.

Everyone and their mother knows rounds under 80 grain tend to have trouble penetrating brush without going off target, the Russians are learning that to their detriment with 5.45. Dickheads reduced 5.56 to 60 grains, and then even made the bullet less dense and had to make unreasonable chamber pressures to get it to remain at 60 grains.
BUT AT LEAST IT CAN GO THROUGH STEEL HELMETS NO ONE USES

AP designation in ammo doesn't mean that it's meant to defeat all armor. It means that it generally has an increased effect on armored targets, and is enough to compromise the armor itself. I get it, you don't actually know anything about weapons, and have probably never even held one, but this is how things are designated. 7.62 has its ball, target, and AP counterparts as well, those also do not pierce Level IV body armor.

His laughter was probably implying that -on real world scenarios- the "AP" label on 5.56 is almost like an oxymoron. A more extreme example would AP .22 short.
I don't fully agree, an AP 5.56 will penetrate some armor more reliably, it could be useful in some scenarios (ie: SBR on urban condition where your targets might have different armor levels).

Or really any kind of round that can deal any kind of damage out to 1000m. It's a must have for asymmetric warfare, because the enemy always pushes the asymmetry.
If all your troops guns are good to 500m, the enemy will simply sell all his assault rifles and buy machine guns that can hurt you from 1000m. Then he gets on faster or more agile transport like a motorcycle, and engages you from mountain goat paths. If you rush him, he has 500m safety zone in which to decide to break off the engagement. As long as he stays in that sweet spot he can kite you and there's fuck-all you can do because you failed to equip your troops to deal with the threat.
The only counter the average US fireteam has is to dig in, get thoroughly pinned down, and then hope a the Humvee with the M2 arrives before the enemys shitty mortar and rocket artillery lands in the wrong place.
Although its true the Greeks are more concerned with piercing at least some armor. There's a reason Greeks adopted the battle rifle as a standard rifle everywhere except the mainland. This is to slow the progress of any invasion force by shooting amphibious vehicles and landing craft approaching one of thousands of Greek islands with amphibious craft. They can engage boats to 1000m and will penetrate most steel plate or hulls at 600m. The fact that sea is flat means engagement ranges stretch out into infinity, giving every troop a .50 cal sniper might even make sense.

I think it's about a 1/3rd with rough calculations based on numbers I'm vaguely recalling.
Taliban don't have a whole series of weapons, delivery systems, strategies, tactics and techniques to pick from - they have two or three. Find the troops killed by bombing (either suicide or IEDs) and subtract it from the total (~10,000) dead, you'll get the troops killed by this >>631119 tactic.
Almost ALL of their effective gunfighting is that tactic, the only other gunfights they do are actual terror raids on civilians and desperation zerg rushes by fanatics, but those aren't effective.
Although "NATO dead" is kind of a weird measure because a soldier shot in the head with an incendiary round can be shipped to a first class trauma center in Germany within a couple of hours and easily survive. Plus a bunch of things hide real DIA stats, by pigeon holing the term "action" and actually excluding some patrols or soldiers caught off duty as "died in ACTION", not to mention the guy who gets shipped to Germany and dies didn't really die on the front lines now did he? And also excluding a lot of support personnel, allied personnel and mercenaries from DIA stats. It's basically statistics turned to propaganda.

The Taliban stopped bothering engaging US forces in protracted gun battles within 300 yards/meters. They realized it was an exercise in futility and stupidity because at the range, the 5.56 is more than good enough for American drills to crush them and lock them down.
So Dshk's and PKMs, alongside RPGs and Recoilless Rifles are the primary attack vectors that aren't IEDs. You should see a pattern, its weapons that can deliver lethal force at around a kilometer or greater, excepting the RPG rounds which autodetonate at certain distances. So against American forces, what has been happening is short, intense engagements with light artillery alongside burst of machine gun fire for the suppressing and disrupting effect.
After 10 minutes or less, the Taliban breaks. And during these engagements, the Taliban have gotten very good at trading for favorable casualty ratios. If it wasnt for the ease of Medivac, they'd come out ahead more than not.

The true question is, dollar-by-dollar who's winning? It's more than expected that a warmachine of the scale and technological level of NATO, with its completely pussified policies regarding human loss, to have much less human casualties than sandy goatfuckers in cave but how much does a human casualty costs NATO in monetary value when there are thousands if not millions of dollars on the soldier's back for his training, equipment and even air-support?
