🔴 The Actual Difference Between 5.56 And 223

all right so what is the difference between five five six and two two three because you can check the outer diameter or dimensions and they're exactly the same i mean yes they will vary from manufacturer to manufacturers slightly like overall length trim length stuff like that but if i had a whole pile of 556 and a whole pile of 223 from a whole pile of different manufacturers and it wasn't stamped somewhere i would not be able to pick out which cartridges which cartridge just by specs and like i said you can go and try this yourself so okay well the specs are exactly the same on the outside well what about on the box well this is two two three it's a 55 grain full metal jacket boat tail it's flying at 3240 okay well here's m193 5.56 it's a 55 grain full metal jacket boat tail on a 16 inch barrel it's flying at 31.80 on a 20 inch barrel is flying at around 3240 3250 somewhere in there so the numbers on the box are exactly the same so why is one mark two two three and one is marked five point five six and some of this information i just recently found out so let's go over it now obviously again different manufacturers you'll get slightly different things but generally speaking when you're purchasing m193 or 5.56 what can you expect number one a crimp primer so on the 556 the primer i you probably won't be able to see it's all just rolling pictures there's a crimping holding the primer into the casing on the 223 there is not now again every manufacturer is going to do something different some 223 manufacturers are going to crimp the primer some 5.56 manufacturers are not going to crimp the primer but generally speaking you will get a crimp primer on 5.56 next one can allure so actually this particular 223 has a can of lure i know i got one without one one second here ah the second one right there that does not have a can of lure and that is marked as two two three again generally speaking with 5.56 you should get a can of lure what is a cantaloupe you may ask well i have a couple examples if you can't see it well don't worry i'll roll in some pictures so as you'll notice on this lower projectile right here there's a cut in the bullet that is so when you crimp it the brass will flow into there and the brass will hold the bullet tighter on this top one there is not a can of lure typically again we're talking about general terms generally speaking without a can of lure you'll get a little bit more accuracy with a 5.56 you should get a can of lure next one full metal jacket boat tail the recipe for 5.56 m193 is a full metal jacket boat tail projectile what is a boat tail obviously this in a 5.56 projectile it's a 338 future product future project as you see it tapers in the rear that is your boat tail it makes the projectile more aerodynamic so it can hold on to its velocity a little bit longer boat tails are the way to go for most applications uh some applications no it's better to have a flat base a different video topic we won't cover that today freebore again generally speaking and there was a guy that took a whole mess of barrels 5.56 to 5.56 wild chambering to 223 chambering and he measured all the three freebores and to be honest there were some two two threes with free boards longer than 5.56 like what the 5.563 board should actually be and some 5.563 boards that were actually shorter than 223 it all comes down to the manufacturer but 5.56 is supposed to have a longer freeboard that is to accommodate the m856 tracer round the m856 tracer round is a 64 grain projectile but the projectile is longer than an 80 grain serum match king projectile that's actually why your ar-15s or mil-spec ones will have a one-seven twist barrel because of the saw program when they were coming out with the m16a2 they wanted to be able to fire the same ammunition as a saw program the saw program shot the 856 tracer and that requires a 1 7 twist barrel because of it's a very unstable projectile because it's really really long and it's really really light so it has a tendency to double tumble so you have to spin it extremely fast to make it stabilize that is why your m16s a2s your m4s everything have a 1 7 twist barrel to be able to shoot that particular projectile when everyone knows that a 1 9 twist is the best barrel twist for 55 or 62 grain projectiles now where the real difference comes in with five point five six and two two three now i'm very new to this information the reason i'm new to this information is because i never purchased two two three when i first got into ar-15s i started looking at like 6.8 spc uh two two three seventy seven green two two three sixty nine grain open tip match and then i realized that oh my god none of these projectiles have advantages over the m193 or the m855 until you get to like 500 yards i'm not gonna shoot my ar-15 that far in my area about 300 yards that's the rule if you find a spot where you can shoot farther than 300 yards you know you're going into that spot so why in this [ __ ] would you take an ar-15 you'd carry something in like a 308 or something with a a projectile that actually does good work at those ranges so basically i run m193 exclusively unless i am running a military-grade sighting system or some sort of military-style sighting system because this is calibrated for the m855 which is the green tip if i'm running this kind of sighting system i throw an m855 so my my ballistics work yeah they would be pretty close with 5.56 m193 but i might as well just run the projectile that it's calibrated for why would i not so if i'm running like an acog with a bdc for m855 or i'm running some sort of a2 sighting system yes then i'm going with m855 but say for example i didn't have this military sight on here and i was just running like a red dot no this would be 5.56 m193 because it's a faster projectile and it has more advantages over the m855 again with the caveat that i'm not running some sort of military sighting system with this particular rifle yes this is an a2 sighting system but it's a national match configuration so it doesn't have the bdc on the wheel so i got my range card with how many clicks i need to turn for different ranges and then i just run m193 out of this because m193 is the better performing 5.56 projectile again like let me rehash here so i run m193 exclusively unless it has a military sighting system which is calibrated for m855 that's the only time i run that because like i said your 77s or 69s all that they don't have any advantages until you get way farther than i'm going to shoot my ar-15s with one catch and that would be 45 grain 223 because this has very unique armor penetration capabilities i've tested this you can go check out my old videos this slides through armor where those two do not so i didn't know that the velocities on the box were for different length barrels so your m193 or your 5.56 the velocity on the box will be for a 16 inch or 20 inch this particular velocity is for a 16 inch barrel and that's cruising for a 16 inch out of a 20 inch barrel it shoots much faster the velocity on this particular box is for a 24 inch barrel and this velocity is still pretty generous because when you use the velocity chart you should only be seeing like maybe a 200 foot pound uh 200 feet per de 200 feet per second difference from like a 20 inch barrel to a 24 inch barrel and this is saying 3240 and when i chrono this this was at 2800 feet per second and i'll i'll play all my chronograph footage right now all right let's start off with remington 55 grain claiming 3250 on the box now gold three rounds of browning 3240 on the box fiocchi 3240 on the box i think i missed one so i'm gonna shoot one more fioke [Applause] i can't remember if the lights got to be blue or orange anyway pmc on the case 3240 winchester m193 okay you too 3205 3182 and just for comparison here's a winchester223 so yeah definitely a difference between 5.56 to get the performance you're looking for out of your 20-inch barrel 5.56 you got to run m193 so that's the real ultimate like noticeable difference your 5.56 this velocity on the box is for a 16 or a 20 inch barrel and it has a specific velocity window it's aiming for your two two three velocity this can be for a 22 inch barrel a 24 inch barrel hell it could even be for a 26 or 28 inch barrel it doesn't have a specific velocity window it's trying to hit they probably worked up this load with their test barrel found the most accurate velocity and that's what they're going with with your 5.56 this is supposed to be a specific recipe this particular brand is it does hit that window and the velocity is what's key because that will push you at 2100 feet per second at 300 yards temporary wound cavity as we expand and recover from is different when projectiles hit at greater than 2200 feet a second at that point it appears we have surpassed the elasticity capability of human tissue and that temporary wound cavity begins tearing at its limits and margins and becomes the permanent wound cavity which also is the conclusion why people who are center-punched with rifle projectiles typically succumb much quicker than people who are hit with handgun projectiles the byproduct of that also seems that when a rifle projectile at those velocities bypasses an organ you will still have organic damage whereas a handgun projectile needs to directly hit a vital organ to do organic damage basically you want to be at 2100 feet per second and whatever range you plan on shooting at i mean obviously once you get to like three and 500 yards no projectiles will do that anymore well there will be some but not very many so then you start looking more at kinetic energy but when you're talking about this kind of rifle with this size of cartridge 2200 is extremely important once you drop below that that cartridge just doesn't have the power that it does with it so to recap the real big difference between 5.56 and 223 is where the velocity is taken from this velocity on 5.56 will be on what size barrels you're going to use which will be like a 16 20 inch 14.5 something like that your 2 to 3 you don't know it could be for any barrel length but the 5.56 is hitting a specific velocity number and that's what we want so should you buy ammunition for your ar-15 make sure it's 5.56 i would go with m193 or m855 depending on if you have a military site if you have some of the military site the bdc is calibrated for m855 so then you want to run m855 if you don't have some sort of bdc military calibrated site and you can set your site for whatever like for example on this or on that particular red dot you want to go m193 because you get the faster velocity and it performs better than the m855 anyway i appreciate you watching my channel if you like the support channel got my patreon right there i also have affiliate links in the description down below even if you don't
