People talk about how the US fricked NATO over with the 7.62x51mm cartridge, but nobody ever talks about the utter mediocrity that is the Belgian SS109 (M855) load of 5.56x45mm, and the compatibility issues it introduced to NATO countries which were already standardized on 5.56mm rifles designed for the perfectly good M193 load.
Frick M855.
>SS109 effective range: 900 meters (more than 7.62 real fricking NATO M80)
>M193 effective range: 450 meters
Any questions?
effective against what?
People, if it hits one. But it has to be fired out of a long barrel weapon and the projectile is so light any wind will blow it well off course.
We are taught that its effective out to those longer ranges at section level, aka everyone is shooting at the same target so hit probability goes up. But that's still only out to 600m
>only out to 600m
Are you volunteering to take a hit to demonstrate the ineffectiveness at 601?
Did you read the fricking post?
It will kill you at those ranges, it just gets so much harder to hit what you're aiming at so its not classed as effective.
Against an unspecified imitator of a steel helmet nobody uses that army picked.
Prairie dogs probably.
You wouldn't usually engage targets directly at those ranges with most 5.56mm weapons, and with 7.62mm you're either suppressing with a support weapon, or you're engaging as a designated marksman, in which case you might use something like Mk.316 Mod 1 instead. If you were looking to engage more than a few targets at that kind of distance with 5.56mm, you'd want Mk.262 Mod 1 instead of greentip.
Sure, but going from M193 to M855 was in the very best of circumstances a sidegrade.
I mean as a military standard, not civilian life uses. If you're just plinking you can shoot some shitass ammo and mayve even get some practice clearing malfunctions, if it's something really bad. Don't go TOO cheap though, it gets dangerous.
>they would have to update for NATO magazines
That wasn't enforced as a standard, hence why the FAMAS, G36, AUG, and others got to stick with their own patterns of mags, for better or worse. Updating the rifles is fine, but it should have been for a good load instead.
>Mk.262
Which is gr8 I r8 8/8, but it's not what every grunt gets issued.
Shame, but M855 isn't that bad so long as it's manufactured correctly
M193 was built for the 1:12" twist
Doesn't make a shit, 1:9 stabilizes it perfectly well. Nobody uses or even makes anything in 1:12 at all anymore. You'd have to go back like 50 years to see a 1:12 twist rifle.
Brownells sold BRN-16 uppers with 1:12" twists
Only because they're making replicas of ancient shit.
>Verification not required.
PSA literally sells 1/12 m16s

>effective range: 900 meters
>a wild skinny appears
>no effective range at all
M855 is an underperformer, but that shit is a myth. Also one of the people involved in that incident is a convicted child molester, doesn't have anything to really do with M855, just mentioning it.
Both kill just fine. Buy which ever is cheaper.
>utter mediocrity
>goes bang
>good for blasting ammo
What's the problem? Is it personal?
>the compatibility issues it introduced to NATO countries
Even if SS109 was never adopted, they would have to update for NATO magazines
>utter mediocrity
Paved the way for Mk 262, meh
>perfectly good M193 load
Still in use, never went away
M855A1, Mk262, Mk318.
>According to US DoD sources, the Mk 262 round is capable of making kills at 700 meters. Ballistics tests found that the round caused "consistent initial yaw in soft tissue" between 3 and 4 in at ranges from 15 feet to 300 meters. Apparently it is superior to the standard M855 round when fired from an M4 or M16 rifle, increasing accuracy from 3–5 minutes of angle to 2 minute of angle. It possesses superior stopping power, and can allow for engagements to be extended to up to 700 meters when fired from an 18-inch barrel. It appears that this round can drastically improve the performance of any AR-15 weapon chambered to .223/5.56 mm. Superior accuracy, wounding capacity, stopping power and range have made this the preferred round of many special forces operators, and highly desirable as a replacement for the older, Belgian-designed 5.56×45mm SS109/M855 NATO round. In one engagement, a two-man special forces team reported 75 kills with 77 rounds.
Yes, Mk.262 is sick stuff. We should just develop a version of that as the standard 5.56mm load instead of the NGSW homosexualry. It would be cheaper, faster, and actually produce a useful and tangible result.
Except it’s loaded so fricking hot it’s blowing out gas rings and barrels

You mean M855A1?
I remember reading somewhere that mk318 was originally supposed to be 70+ grain weight, but it was changed to 62gr for bdc compatibility in acogs.
>In one engagement, a two-man special forces team reported 75 kills with 77 rounds.
Fricking aimbotters.
>mfw my main home defense rifle is an AUG
>1/9 twist
>only use 55gr M193
I'm here for basketball size exit holes my dudes.
Meant to specify it's a 20in barrel. M193 loves a full 20in barrel.
Unfathomably fricking based, make shit look like a Paul Verhoeven movie.
Holy cringe. Come back when you are 18.
Actual adults use a suppressed 7.5"-10" 300 blackout
I'm not a zoomer who grew up on Colladoody, I'm perfectly good with exploding home invader eardrums and making meteor impact craters in their heads and chests.
>I'm perfectly good with exploding my own eardrums and making meteor impact craters in my sleeping dog in the other room.
>not engaging home invaders with a welding mask and electronic earpro
>5.56 SBR
Better of with a 10/22 at that point
>5.56mm means shooting randomly like a moron
>electronic earpro, 5.56mm suppressors, or linear comps, do NOT exist
Even out of a 10.5" barrel, even with M855, 5.56mm will shit all over 5.7mm at HD distances (and beyond). I'm comfortable with not having icepick wounds.
>not going with a 5.56 SBR with a linear comp, binary trigger, and 10.5" barrel
>not engaging home invaders with a welding mask and electronic earpro
The US can frick over whoever it wants... without them NATO would be toothless
If you could read, you'd see that I'm actually complaining about the fricking Belgians.
