>3153FPS with 62gr loadingOvermatch against carbine barrel lengths
Damn 14.5'' is fucking pathetic huh
>>64610970Well the graph only shows from 2800 to 3200 but yesIf anything 14.5 still mogs 10, 11 and 12.5
>what the full graph would look likewow. such overmatch
>>64612535>except energy doesn't scale linearly with velocity
>>64612913>Chasing 200 FPS when you're already supersonic
>>64612918>Said 200fps being the difference between 200m of fragmentation range
>>64609561I was just thinking if theyre loading the xm7 caliber to pissin hot bubba levels to pierce armor at range why dont they just make 5.56 pissin hot too?
>>64613573You dont even need pissing hot, you just need a few simple drop in mods to the m4 to handle slightly higher pressures and then use the rest of the r&d on material sciences for the bullet design
>>64613474So now it's linear? You were just arguing it isn't linear
>>64609561>>64613474the whole premise of the thread is stupidone side isn't going to go>haha we're getting shot at 600m but it isn't fragmenting. fight on!people fight until they get shot and then they stop fighting. there's no "fragmentation overmatch". pure keyboard general nonsense
>>64614152Flatter trajectory increases the soldiers effective range with magnified optics.
>>64614036That post didn't argue it was linear.
>>64609561why do burgers measure velocity in frames per secondmy cars going 60 fps vsync just kicked in yo
>>64614369my badthe bullet is traveling 2149 mph
>>64614348wow such flat>>64612535
>>64614492millipicohours would be a unit of timenot velocityyou triple baka
200fps is angels dancing on the head of a pin when the low end is already 2900.It's a fast bullet, if it hits something it's going to hurt.I'd challenge contrarians to go outside and try to shoot 400+ yds and hit a man sized silhouette with 5.56 before worrying about what the impact on the target will be like.
insane that consensus is still heavy profile short barrels vs pencil 20"s
>>64615497>>64614152You can get literally +100m extra range at the same kinetic energy for free.For a fragmentation dependent cartridge that might be a 30% increase to your effective range depending on various conditions.And that's not even considering loadings optimized for longer barrels.
>>64616008>For freeWeight at the end of your gun isn't free, infantry marksmanship via better optics also matters more, the Acog made more of a difference for killing enemies than 20 inch barrels.
>>64616022The AR platform is already incredibly light. Just lift weights. Lethality with 20" and magnified optics increases just like 14.5" and magnified optics.
>>64609561Trying to squeeze blood from the 5.56 stone might be why we just adopted a whole new cartridge.
>>64616022>7 pounds unloaded including ACOG>too heavyok
Fragmentation literally doesn't matter is not desirable.>b-butAll you're doing is limiting penetration. Projectiles moving that fast do NOT require fragmentation to expand the wound channel.As everyone with eyes saw, Rittenhouse turned commie retard's arm into pink mist. This is significant because that is how rifle calibers work. There is nowhere near enough time, especially with anemic .223, to fragment in a bicep. No bone was struck to force fragmentation either. Projectiles moving that fast cause vast wound channels and exceed the elasticity of human flesh.
>>64618128Rittenhouses case is the PERFECT example of why you need more velocity, ie. 20''
>>64618135...Why?Instead it demonstrated that already seriously gimped .223 that is severely underloaded, fired out of a 16" barrel, causes massive wound tracts without fragmentation.Your 200 extra FPS doesn't matter. It never did. It never will.
>>64618141>already seriously gimped .223 that is severely underloaded, fired out of a 16" barrel, causes massive wound tracts without fragmentationAt a distance of zero meters...With a 20'' barrel you can achieve the same horrific wounding out to 100m and decent wounding out of 200m and acceptable out to 300m
>>64618144And the same goes for actual 5.56 out of a 14.5". That's the part you're glossing over.With a 20" barrel you get the same results and zero benefit. That is why nobody uses them anymore.
>>64618148As you can see here>>64616008A 20'' barrel will produce rittenhouse level damage out to 100 meters whereas 14.5'' will have already degraded in performance. You can cope with "still good enough" all you want but 20'' simply has a 100 meter range advantage.
>>64616008Nah you make a good point anon, longer barrels do have a significant advantage here.However I still believe most anons are talking from their asses until they try to shoot a target at 400yds.
>>6461822714.5" and 20" to the chest or head have the same effectiveness
>>64616443>>64618112Way to not read. I never called it too heavy, but it is heavier than a 14.5 and anyone who shoots knows lighter is always easier to manage. If you wanna be tryhards post your 20" builds.
Twig arm 20" barrel PUSSIES will never experience 5.56's TRVE potential

>>64619042>7.62x39Quit pulling my dick, but nice regardless.
>>64619052That's 70 extra fps buddy. That translates to an extra 20 yards of effective range, effectively turning me into a long range sniper build, easily laying waste to entire squads before they can even return fire
>>64619086Kekkkkkk
>>64618649They don'tEspecially at 100-200m
