As .300 blk's number 1 fan, it was never meant for penetrating walls and stuff (which is why it's a good home defense round), it was made to hit hard and dump it's energy.
And do so from a short barrel while SUPPRESSED. Highly maneuverable, quiet, less likely to over-penetrate, and dumps a LOT of energy into the target. Wonderful round.
@1978garfield - I just looked it up. You are correct. Subbed to it also. "It's time to grind." 🤣🤣🤣 I remember, about a year ago, someone suggested that in a comment.
I've seen a lot of tests with both of these rounds both near and far range, there's no question the velocity of the 556 is great , the 300 blackout 9" can range out to 500 yards in 125 grain weight, the 110 vmax is absolutely devastating at 2400 fps , 300BLK is probably the most versatile with all of the different bullet weights both near and far. The true magic of the 300 blackout was in CQC close quarters combat in a subsonic 1000 fps. 190-220 configuration with a suppressor allowing soldiers more hearing protection while clearing building in villages across the desert in the Middle East such as Fallujah one of the most dangerous conflicts we've ever fought.
300 blk being a heavier round, slower round actually penetrates drywall pretty well. 5.56 being a lighter, faster round tends to dump its energy, fragment, or destabilize, compared to 300 blk. Food for thought.
i remember being a kid and these or preying mantis being like "aliens" to me! You only rarely saw a mantis and sticks were even more special to see! I think everyone has so damn much bug spray in their yard most of this sorta thing is just a memory. Kinda like lightning bugs. We see MAYBE a swarm...of 6. Being a kid in the 70s...hundreds.
The reason the velocity loss is so minimal between the two is that you chose heavy for cartridge 77gr for 5.56 and light for cartridge 115gr for 300bo. If you ran 55gr in 5.56 and 150gr in 300bo, you should see a much greater disparity in velocity loss.
@@allanhood4397 I can't afford anything. I don't currently own firearms. Haha. Just really interested in how the round stacks up in a fun video on ballistics since physics and ammo types are something I am super interested in.
@@_aiviator_ I seen a video with 8.6 bo testing barrel twist rate. And the barrel that had 1:3 twist rate was way more devastating on the gel test. Pretty interesting I thought!!
@HatsuneM1ku01 Interesting, but I've never even seen a 64 grain round for sale. And the 77 grain Black Hills round is pretty well proven in combat, so I'll probably stick with it.
Banana! A test of 5.56x45 vs .25-45 sharps would be awesome! I know you probably don't have an AR chambered in it, but the one and only thing you need is the barrel. Takes the same mags, buffer, BCG as a regular 5.56 AR. I would love to see the difference in performance.
You can get 9mm subsonic that's almost as heavy (185 grain), with a much smaller case, and that fits in a smaller, lighter, cheaper gun. But then with .300BLK you do have the option of running supers with a lot more energy when you don't need to be quiet.
@@AlitaGunm99 Sure, but those rounds will almost certainly cost as much as subsonic 300blk, be even slower, have a worse ballistic coefficient, and still have less mass. Looks like they're only in +P loads as well, so you'd be limited to using them in something rated for the higher pressures. Not to say that 9mm is a bad choice in most cases....I'd just stick with more normal rounds with slightly less energy if I was going to compromise anyways (especially if cost was a concern).
@@joshrandall3632since when do you get 1000+ ft lbs of energy from any length .45 acp firearm? Ooooh, look at that, someone else tried to do the thing of comparing the subsonic rounds to .45. Wow, of all the times that happened, that was another one. Nice try.
@@CrashRacknShoot 😂😂😂 You sound like one of those kids who's never shot anything bigger than a Nerf blaster. There aren't any subsonic BLK rounds that even come close to 1000 fpe. Keep trying and study hard and maybe daddy will let you shoot a real gun someday kiddo.
Compare energy loss, not velocity: Expansion volume matters (or more exactly expansion ratio) So, a larger caliber is able to extract more energy from a short barrel than a smaller caliber, running similar case volume at similar peak pressure.
I think the main reason the velocity loss is similar is that you're comparing one of the heaviest .223 to one of the lightest 300blk. Heavier rounds tend to lose less in shorter barrels on account of the higher dwell time and lower powder charge.
@@markhunter2342speed penetrates. That's not the test. Barrier penetration is only one small facet of firearms. Best to not much too much stock into this. Fun info to have, though.
@@CrashRacknShoot Yes it's a complex issue but weight also has a lot a baring on it and so does bullet construction, target construction etc. Look at big game rifles for example.
Every tool has its purpose, depending on the need of the operator. If you want range and penetration, 5.56. If you want high impact at close range, .300 blackout.
I think you just made the case for 300 blackout. It destroys what it hits without over penetrating. Effective cqb round in a super short barrel that can be near silent with sub sonic. I’ll take one for home/truck. Keep the 5.56 at 14.5” and add a comp or suppressor.
Good stuff, i was confident goin into this 5.56 would do aight lol. Its an amazing little cartridge, especially when youre someone like me that doesnt stress "TOO LONG" of a barrel. 😂 my shortest 5.56 rig is a 13.7 and also have a 20 inch and a 24 inch heavy barrel rig, that thing SHMACKS! 😂 ive put alot of meat in the freezer and put down alot of pests like beavers and coyotes with a 64 grain 223.
Great highly scientific video Double B. ❤ You are doing exceptionally well. Over 150k subs already! Congrats! 🎈🥳🎈 I think the 556 won ALL these tests. It hit the steel harder after the juice. But I'll submit to whatever Terry says. 😒
I thought the velocity loss for the blackout would be an unfair comparison since the lower numbers would be bigger relative percentages. But a KE comparison has the same results. A 77gr going from 2619 to 2365 has a Ft-Lb loss of 1173 to 956, and has 81% of the 16” energy. A 115gr going from 2345 to 2146 has a Ft-Lb loss of 1404 to 1176, and has 83% of the 16” energy
should try loading the 123 grain penetrating steel core rounds that came in russian surplus 7.62x31 ammo, 150 grain fmj BT or the 208 grain ELD loaded into the 300 blackout, you can also load the 62 grain green tip into a sabot and fire it out of 300 blackout.
300 blackout is not designed for maximum penetration. In fact, it is designed to not over penetrate. Your results showed it doing exactly what it was created to do.
@@HatsuneM1ku01 I saw that video, but it was out of 16" barrels. I'd like to see the results out of 12" or shorter barrels 7.5" in particular. For SCIENCE....
Imagine being a cricket, minding your own business, some hairless ape pokes you with sandpaper rock shards, you hide in a crack to get away from him, and suddenly you are living the gunpowder barrel trap scene from Sherlock Homes.
The cool thing about 300 blackout is just how much it can do with a stumpy little barrel. No, it’s not the greatest round ever, but it may be the greatest round ever for an SBR.
300 Blk seems superior for defense. Put a supressor on and use sub-sonics. The 300Blk will shine, especially with the heavy subsonic monoliths available. The 5.56 will deafen everyone in the room. Two different uses. 300 BLK really works well as a quiet subsonic pistol, while smaller 5.56 needs that supersonic energy to stay useful with a short barrel.
Would love to have some text on the video for the different calibers. I'm taking a stroll in the video, not cruising sorry, and I'd love to be able to see the difference at first glance. Great content anyway, keep it coming !
I dont really mind enjoying content on this subject in particular, however i think thay its somewhat misguided because the rounds have 2 entirely different purposes; and often times we find creators score the bo low on the fact that it doesnt perform well past 100 yards. Okay, and microwaves are horrible at deep fat frying turkey; because its not designed to. I love how KB gets right down to the type of comparisons that matter.
People really underestimate the ppwer of many rounds even out out tiny barrels, and really overestimate just how much more power medium and long barrels give said rounds. For example, the difference between a 14.5 inch barrel and a 20 inch one is just 100-150 fps, which in terms of them both going about 3000 fps, is really miniscule. Someone said that, at least in 5.56 you can expect a loss of about 20 fps per every inch of barrel you lose, ehich is again, pretty miniscule. The drop is probably a bit more dramatic when you get to way shorter barrels, but it's still probably not going under 2200~ fps if there's at least a couple inches left.. That's just a 25~% drop in velocity, or 40-50% drop in power over a very long barrel at most. Thats in a very tiny barrel, in a 5-6 inch barrel, its going about 2500, aka, about half the lost velocity, and just 20-30% less energy. Just off the top of my head, dont have the ass to do proper calculations. And since penetration is more or less linerar, you're looking at only about the same 20-30% penetration loss, which yeah, is indeed way less intuitively dramatic considering youre comparing a 5 inch vs 20-24 inch and would probably expect a drop of the same 75-80% instead, but eh, physics is kinda weird unless your intuition was formed with it in mind, which for most it wasn't
If you want to perforate steel FMJ IS the way to go. That or Barnes X solids. Keep in mind. That 556 can be deflected by branches and other obstacles between you and your objective. Not so with.30 caliber blackout...
77gr 5.56 SD 0.221-ish 115gr .308SD 0.160-ish Sectional density is the highest predictor of penetration. My numbers should be close but makers have their own actual numbers.
To be fair, after going through that much wood, I really don't need (nor want) enough remaining energy to put big dents in the steel behind it - that's just energy that go wasted on the landscape *behind* the target, rather than contributing to damage *to* the target. After all, when Im looking at 7-10" barreled AR15s, I'm not planning on using it for bear or elk, so I don't need tremedous pemetration. Nor am I terribly worried about shooting a guy hiding behind a USPS blue mailbox on the street corner. So, .300BLK demonstrates performance more matching my intended use cases. Also, from a short barrel like that, .300BLK has a lower uncorking preasure when the bullet leaves rhe muzzle, and is less detrimental to your situational awareness if you aren't shooting with a suppressor.
You better not shoulder that short barrel rifle. The ATF is all knowing, all seeing, and everywhere present.

After all, when Im looking at 7-10" barreled AR15s, I'm not planning on using it for bear or elk, so I don't need tremedous pemetration. Nor am I terribly worried about shooting a guy hiding behind a USPS blue mailbox on the street corner.
So, .300BLK demonstrates performance more matching my intended use cases.
Also, from a short barrel like that, .300BLK has a lower uncorking preasure when the bullet leaves rhe muzzle, and is less detrimental to your situational awareness if you aren't shooting with a suppressor.
2:45 story of my life a pin hole going in but still blowing out the back
Tungten shots vs lead and steel? It would be interesting.
5.56nato from short barrel- 22 mag
.300blk from short barrel- .300 blk
You think that 300 blkout 115 acc round would be good for deer out of a 16 inch barrel?
VERY EXCITING🎉

Never in a million years did I think I'd see a Max Keeble reference in this comment section.

Why no brace? 0:35
Can we get 300 BLK vs 7.62 x 39?
This would give you an excuse to get an AK pistol if you don't have one.
