omfg the shill retard thinks all the 7.62x51 arguments are by people who think it's better and not using it as a snapshot of all the downsides of a full powered cartridge and why they still apply to .277

Where the actual fuck are you seeing this being argued? Is English your first language? The 25 round 7.62x51 mags are being used to show how impractical they are and by extension the 6.8 ones will be.

You are profoundly stupid and your (lack of) vocabulary demostrates it. The word "sidegrade" might be the zoomie gaymer equivalent of SJWs saying "problematic". A meaningless sentence decorator that they think is some profound zinger.

If you are already invested in 7.62x51 as several anons appear to be it is indeed a hard argument to make to switch to 6.8, but the context here was the US military.

Where did you hear that it was a mix? That would make machining the tungsten easier though if it is just the blunt forward projectile.

Yeah it stops .50 BMG M2AP with 40mm BFD, which is a pass under NIJ requirements. Granted, out of a Barrett and not an M2HB. Also it's 9.25lb and 1.488" thick.
EDUN on Taobao sells an 8.8lb / 1.44" thick plate good for 1x 12.07x108mm B-32 API at 50 meters standoff, but that's an inferior round. You CAN actually buy it unlike the Colossus Heavy for $1,020 a pair. I'd use it as a "threat level unknown" plate for emergencies because of the strike face thickness.

It won't do 2,900ft/s, which is implied. Buff is told what to shoot in advance. He pretends he doesn't but he does.
>>20787
The regular Colossus is $1,280/pair, since this is mostly beefed up strike face and they use cheap PE, I'd reckon $1,700/pair.

If those plates reliably stop fiddy AP at close range, then it seems to me that developing infantry rifles GPMGs for any further armor penetration is pretty much a lost race.

Yeah that's more M2 velocity. The plate is single strike so if you're getting engaged by an M2 it's tough fucking shit anyways.
I would like to know why Adept hasn't commercially released that plate. They could use their new Ivoryguard trauma foam to get that 40mm BFD down some.
Remember, it's not just BFD depth, but also velocity of the deformation and width. VPAM is a better standard than NIJ for all of those, but there's no way Adept is doing a 3-shot PM-13 plate for less than maybe 10.6lb.

Those Colossus plates could be defeated by .270 or M855A1? It doesn't seem likely to me.
Not that wearing one of those makes it an appealing proposition to get shot at by either, there's lots else of your body it doesn't cover.

No, we're joking about 9lb steel plates. M193 at 3,250 will fuck them up except for the newer harder steels and the steel-titanium alloy plates like AR500's really overpriced A4 which still loses to M855A1.

They are over 9lb dude. Upcoming GEN-IV XSAPI is 5.5lb standalone and that's still considered heavyweight emergency armor by US military standards.

Yes, but if you can make a 9lbs plate which stops .50BMG AP from a Barrett at close range, then you could most probably make a much lighter plate which no-sells whatever NGSW shenanigans one could come up with.

Certainly. Take the Colossus and beef the strike face up until it's 7.7lb, same weight as a Hesco 4403.
You now have a $1,500-$1.6k a pair plate that is too heavy for mainline infantry use but is acceptable for emergencies and counter-sniper.

Replacing .308 with .277 is actually a good idea. You get a better round in every metric including being more compact. Much like how 30-06 to .308 was a direct upgrade.
My annoyance with the M7 NGSW program is the lack of GPMG/SAW. The M7 is a BAR, which was a suoerweapon for WW1, excellent for WW2, and still relevant in Korea. The BAR is why the M1 Garand turned into the M14. The NGSW is accurately compared to the M14. Adequate in all aspects, but an obsolete battle rifle and not an assault rifle.
The sad part is the .277 GPMG of a rechambered or scaled M240 is literally the easiest thing you could do.
