I really enjoy this 556 vs 308 comparison. These are my two favorite rounds. It would have been interesting to see the barrel length and twist for my information.

OA. Good and interesting video. Thanks for all of your work. Great shooting and thanks for sharing. Take care.

I’ve used that opening on one of my vids too

it was more like 10 & a 1/3 revolutions.

Barrel length?

Crazy results though. Thank you for the video

Surprised you didnt also test 5.56 m855 ball. Feel like that would have been a better match to the m80 ball.

I didn't think the 556 would be more devastating at 300 uds than 308

Good show 223 is not a 556 interesting,would of liked seeing the pieces of frags thanks

Exactly as designed, 5.56 kills at 300 yards in devastating fashion, while the 308 and 7.62 are designed for 1,000 yard kills.

what is it ? ohh hyperstatic shock ouch

The silver tip of make an awesome deer or antelope load

Age of the plastics makes a difference.

Speed is the killer take a TNT varmint grenade bullet maxed powder load over 4k fps if i remember correctly 32 or 35 grain solid copper bullet

Another excellent video, thanks for making and sharing these.

That was an excellent demo! thanks for putting this all together and sharing it.

Manufacturers rate .223 velocity out of a standardized 24" barrel.

A 5.56 fmj would've been a nice comparison.

Good video!!!!! You made leary fun......

I thought 7.62x51 was the same as .308

Animal flesh is thicker than water. I've seen many videos that "prove " the same thing for 17hmr. Sometime I will do the Paul Harrell meat test and find out the real answers. Just one example, 17hmr will go through a treated 6x6 but the 22wmr will not. Animals are not made of wood but they're not made of water or jello either.

.566 is a lot of bang for your buck.

Should try a 53 gr Hornady Vmax @3400 fps in the 5.56.

Nice video - Thanks!

with everyone's opinion What would be the best Zero for a 5.56 77grn otm 16" Barrel ?

Should have compared with 6.5 Creedmoor as 3rd rd..

556 is not better than 308 lol . 308 just punched right through

Good comparison using similar barrel lengths. I don't think you can expect the same expansion from live tissue as you'd get from clay, but it does give a good comparative sense of the cartridges effect.

I have a 300 sm that will hit that red circle at 300 yds

those jugs are really tough plastic ...

Would love to see a comparison to a .308 110 grain or 125 grain hp or soft point. I used to load 125 gr .30 cal to about 3000 to 3100 fps - DEVASTATING! Thanks for a great video!!!

What is the most reliable ammo Loretta 30x

The more i learn about 5.56 the more amazed i am. Such a tiny little thing. Cookin.

Shot placement anywhere in the orange circle is great shooting , and anyone who doesnt think so has never done any long distance shooting .... 😊

All in all , great video work 😊

but the 168 carried through and hit bank behind and you could hear a ricochet cool video

Your videos not only help in deciding what ammo to use , but also the type of weapon and barrel length and twist ... yes better shot placement would also help

Next time I hope you compare bullet damage with same barrel length. And hallow point on all bullets

Kel-Tec, while I admire your ventures in innovation, you need to stop doing risky and goofy stuff and go back to making good light small .32's.

Fun times!

Good video but next time please show rifle type & barrel length. Everyone likes to make comparative measures to their own rifles.

Kind of funny seeing "slow motion" replays on rounds exceeding 4k fps - it'd take a camera more expensive than my Subaru to get a slow-mo on those rounds! The more videos I watch about the 204 vs 22-250, the more the 22-250 seems to be the wise choice. Not because of its more destructive bullet weights, but the cost of & scarcity of 204 ammo. Regarding the barrel life of a 22-250 vs something like, say, the .243 or even the .223, I'd still opt for the laser accuracy & incredible velocities of the 22-250, especially for fast-moving animals like coyotes or foxes. I've read on some channels that people have even taken moose with 22-250 due to the tack-driving accuracy of headshots - something this beginner doesn't dare try.

Yeah, there's definitely something wrong with the ejection on your Glock. That's not normal.

I don't see a need to get a 6mm Creedmoor, because I already have a 243 which already has a larger case capacity.

Very surprised impressed with the 5.56 results.

I would like t see that same experiment, using the same calibers. out to 500 or 600yds. being I am a huge fan of 5.56, and 7.62/308. I was very impressed with the hydrostatic shock of the 5.56 at 300yds. I would however, like to see other popular 5.56, and 223 ammo at that 300yd range

finally someone shows effect of the most popular calibers, at typical a combative range. as a suggestion maybe use food coloring for visual effect.

Wow! I am pleased to see the piwer of the 5.56!

The biggest advantage I noticed as a Brit going from a 7.62x51 SLR to the 5.56x45 L85A1 was a lot quicker and easier to train recruits to shoot accurately with it at typical combat ranges, it didn't require the same level of consistency in hold and position, its 'easy mode' shooting compared to the SLR - all the power in the world is not much good if you cant land it where it needs to go..

Was fun to watch
