55gr Taiwanese made Wolf Gold .223, which is actually M193 but is marked .223 due to Taiwan's laws. It works great for the citrus hordes of any stripe!
Having used the 55 grain ammo in Vietnam I can categorically say that the only time a target didn’t fall dead was when I missed. Not to say that someone else had a different experience, but that round did what it was supposed to in an M-16A1 in the Mekong Delta during monsoon season and with it covered in mud. Did have to keep it clean but mine worked every time I needed it to work

In my opinion algebra is harder. Calculus is more abstract and takes some open mindedness, but algebra is more calculation intense. Linear algebra gives me nightmares
DeffKanGrotling44 How bout that deadpan look when he fired that A1 in to the ground. I wished I had some corn popped right about then. I knew it was gonna be another good one.
IKR ... It's like his signature gesture It's like he is saying : "Waddaya think is gonna happen ... ?" I love the way he seems to cover all the bases, and treats them all as legitimate inquiries, even though some seem obvious to me. But then, after his little experiments, I've been surprised a few times, proving I don't know as much as I thought I did.
I am an engineer with one of my undergraduate degrees in physics. I have also been reloading and shooting for almost 50 years. This guy is pretty good at consistent testing procedures and uses the scientific method the way it was meant to be used. He is getting answers, not doing bogus testing to support the answer he thought up.

The 55 gr FMJ was not designed to tumble. Here’s the scoop... It’s essentially a non expanding varmint projectile. All such .22 centerfire projectiles have thin wall jackets, and the ones employed by the military for use in US semi & full auto rifles have a “cannelure” located on the side wall of the jacket. This cannelure, or rows of small grooved depressions ringing the copper jacket exist to enable the brass cartridge neck to ‘lock into’ and better grip the projectile during the crimping process at the ammunition factory. This is important due to the bidirectional recoil forces upon the cartridges when the gun is firing. Those projectiles sitting in their cartridges in the magazine without a cannelure would otherwise break-free from the case’s crimp during sustained fire resulting in them sliding back into the neck of the cartridge.case. This would result in feeding malfunctions and possibly excessive chamber pressure. Also, FMJ, spire point / spitzer-shape projectiles tend to rotate from their nose-on orientation to a 180 degree base-forward orientation when penetrating soft tissue. This is because most of their mass is in the lower half of the projectile and the resistance to penetration imparts a rotational force. However, once the projectile completes a 180 degree tail-to-nose reorientation, it remains oriented that way as it continues to penetrate. It however does not continue to tumble as some claim. Now here’s the kicker...It was discovered that when the 55 gr FMJ when fired from the 5.56 out of a 20” bbl, and with terminal ranges out to ~ 100 yards into human flesh...well the following phenomenon occurred: As the projectile was halfway through its tail-to-nose reorientation flipflop, the dynamic stress upon the projectile would cause it to fragment in to 4 pieces. The nose would come apart into 3 approx 7 gr.fragments, plus a 25 gr back half. This caused some nasty flesh wounds which enhanced the cartridge’s combat effectiveness. However, this was not an engineered feature of cartridge. The newer 62 gr “ green tip” projectiles however tend to penetrate in a nose-on orientation (when fired from barrels with suitably faster rifling twist rates). The green tips out-penetrate conventional FMJ projectiles, but they cause less tissue damage.
@Loonytoones85 - It is a Geneva Convention work-a-round, after a fashion. Eugene Stoner and his team were handed a very tough set of design criteria. Their new automatic rifle (assault rifle) had to be much lighter, and have lighter ammunition, than the M-1 Garand and M14 which came before it, yet wounding capability equivalent to or greater than the M-1 Carbine. Using full-metal jacket ammo, since the Geneva and Hague Conventions both prohibit the use of expanding or hollow-point ammunition in land warfare. Stoner is on record as stating that he took advantage of a peculiar characteristic of light projectiles fired at high muzzle velocity - their dynamic instability and tendency to yaw in comparison with heavier larger-caliber projectiles at similar velocities. When it was discovered that 55-grain FMJ fragmented at muzzle velocities above 2800 fps, a "crimping groove"or cannelure was added to the M193 design to make fragmentation/shattering more likely. It also had the added benefit of making the ammo safer to operate in rapid-firing automatic/select-fire weapons. The most-lethal envelope of M193 55-grain is at or above 2800 fps, the velocity necessary to provoke shattering/fragmentation, and thus the formation of a high-velocity blast cone of fragments at the intended target. M855 was designed for enhanced penetration of mild steel plate out to 500m, of the kind used in military helmets such as the Warsaw Pact helmet of the Cold War, but this capability was purchased at the cost of the fragmentation effect seen with 55-grain FMJ. This "ice-picking" effect was seen and well-documented at the Battle of the Black Sea (Battle of Mogadishu), the famed "Black Hawk Down"incident in the early 1990s - where elite Rangers and Delta Force personnel saw Somali militiamen absorb multiple center-mass hits with green-tip 62-grain M855, yet remain in the fight. The dramatically-inconsistent performance of M855 prompted a great deal more R&D into ammunition for use in AR platforms, which eventually bore fruit in the global war on terror.
@Loonytoones85 - A lot of nations did it. Britain engineered their Lee-Enfield .303 cartridge to have a lighter forward section by using aluminum filler. Some militaries/nations do the same thing to lighten the front by using an air pocket. The point being to get the projectile to "swap ends" and perhaps fragment during the terminal ballistics phase of flight. Even if the bullet remains intact, as it transitions to a nose-rearward attitude, it will widen the permanent wound channel. With so many nations/militaries looking to get around the Hague/Geneva Conventions, it sort of makes you wonder why they bother with them at all. It isn't as if there is a whole lot of logic in much of the reasoning anyway. HP bullets are forbidden, but napalm and FAE munitions are not? Expanding bullets are illegal, but not all sorts of mines? I don't get it.... As U.S. Civil War General Sherman said "War is cruelty and there is no reforming it."
@@GeorgiaBoy1961 I recall reading somewhere that the reason the Hague Convention outlawed expanding projectiles was not for humanitarian reasons. It was because militaries realized it was better to severely wound an enemy soldier rather than kill him outright, since the adversary would expend a great amount of resources caring for wounded soldiers, as opposed to none for the dead. Whether this story is accurate or merely cynical revisionism of an actual humane gesture, I don't know.
I have the hardest time watching just a portion of Paul's videos. I end up watching the whole thing, sometimes twice, then before I know it I'm in trouble with the wife for not getting anything done. When she hears me chortling to myself over some witticism or other, she knows I'm not getting anything done other than learning a lot. Nice work, Paul!
I've only recently started watching Paul's videos but I'm already thinking they're among the most useful and interesting everyday world videos that I've seen from anybody. I also enjoy his calm voice, easygoing manner and most of all, the absence of any tacticool pretense.
I knew there would be a difference, but I expected it to be significantly MORE difference. Next week we will film a comparison of AR's with 20" 16" and 10.5" barrels.
I think his a1 just has a slow barrel and or loose chamber. Lots of his velocities out of it are slower. I get 3170 fps out of a del ton 16 inch middy with m193 federal. My 20 inch a2 build was getting 3280 with m193 federal. Both have nato chambers fwiw.
Shasta should capitalize on this and change the way its containers are called. Introducing the '9mm' 12 oz. cans, , the '.44 mag' 1 L bottles, the 'single stack' 4-pks, the 'hi-cap' 6-pk, etc. Never mind: I just remembered about political correctness...
I have NEVER heard of his channel being "underrated" once. Even other RU-vid gun guys give Paul massive praise. I get your drift, I think you just chose the wrong word. Under appreciated would be more apt. This guy should have a sub from every gun owner who uses RU-vid.
@@valuedhumanoid6574 omfg fuck off...the guy was giving paul praise and credit. Just because someone just discovered his channel?...seriously. Some of us don't sit on ass and watch shit loads of youtube all day...
On the topic of 55gr bullet tumbling, it was discovered back in the 1920’s by what’s been dubbed “The pig board,” a study on bullet lethality conducted by a board of general officers on pig targets, that small caliber bullets had this tumbling property resulting in high lethality. At the time this was not pursued, but in 1954 some additional research as well as pushing from a General Wyman in army procurement lead to a draft set of characteristics being developed by the army which were brought to Stoner to develop his then recent AR-10 into a high velocity .22 caliber rifle meeting the requirements. The original specifications were for a 1:14 rifle twist, just barely meeting stabilization requirements for the bullet and designed to meet the power requirement of penetrating a steel helmet at 500 yards. The original .223 remington cartridge designed in parallel was very explicitly designed to capitalize on this stability dichotomy to maximize lethality. The later 5.56 standardization does not make any mention of it, and the twist rate was reduced to 1:12 due to cold weather stability concerns around the time the army insisted on adding a forward assist. I would recommend finding a copy of Col. Hallock’s report on the M-16 rifle program for an exhaustively well sourced discussion on the development and procurement.
When I bought my 556\223 bolt action rifle with an 18" barrel I was worried that it was too short and I'd be giving up too much velocity. I feel a lot better after watching this. Thanks Mr Harrell
That was the most impressive part of the video to me, I can barely read the microwave clock across the kitchen not that it is ever set to the correct time.
My thoughts exactly! I was thinking: Wait, has he memorized the results and is faking this, or can he actually read digits at that distance? Man, I need to make an appointment with my ophthalmologist first thing in the morning!
Could you read the time off an illuminated alarm clock 7 yards away? If so its not so amazing. If not you may need glasses. Not saying Paul isn't amazing, but this isn't why.

Even though it was 18 minutes long it didn't seem that long, and good thing I watched this I was heading out to the hardware store to buy up some tile body armor
Watching this 4yrs after it was posted, I still laugh hysterically when you demonstrate how an A1 will definitely fire M855. Blahahahahahaha the face while firing into the ground lol.
Another great video. Paul is quickly becoming my go-to source for real, level-headed information. The M855 was designed for the M249 and the M16A2, both of which have 20 inch barrels with a 1:7 twist designed to stabilize the M855 and the even longer tracer round. The round will penetrate a 1980s era Soviet helmet at 550 yards. This is better than the M193 or even the M80 ball round for the 7.62x51. However, as mentioned, the steel tip makes the bullet more complicated and leads to inconsistent performance, especially from the shorter barrel of the M4 carbine. The accuracy issue can be easily overplayed for a combat round. Generations of Devil Dogs have qualified with this round out to 500 yards. I used an old A2 that was probably almost as old as I was and only dropped 5 shots from the black at the 500 yard range, including qual and all of the week practicing. The round wasn't designed for jack rabbits and is accurate enough for the vast majority of combat use. Finally, all spitzer (pointed) bullets will tumble because their center of mass is located near the base, so the rounds will naturally flip in a medium that is denser than air. That is why the bullets are spun by the rifling to begin with, rotational inertia gives them stability. The green tip round will tumble reliably but requires a higher velocity threshold (around 2700 fps) than the M193 to fragment, and again, because of its relatively complexity, the M855 will be less consistent.
Removing the green paint on M855 with some witch-hazel will help increase accuracy a little bit.... but if you really want accuracy out of 5.56 you should use 77gr smk otm. M855 is not a sniper round and is capable of the 4moa the military specifies
Green tip is good for anti vehicle threats and punching through doors and thin plate steel. Not to mention it's fun to play "what will this bullet go through"
Msw 96 never under estimate 55gr, though. One of my friends made a target out of some 3/8” mild steel plate. Lead core 55gr out of a 20” barrel punched nice clean holes through it.
@@CountArtha I keep some green tips around just in case I need to shoot through a vehicle or soft body armor. My go to home defense rifle is an ak in 7.62×39 with Tula 158 grain soft points. I'm sure most home defense situations can be handled with my 9mm but it's nice to have options.
@@CountArtha yes it does less damage, and over penetrates . M193 will kill the bad guy and not even penetrate the back of his shirt hardly. M855 will wound the bad guy and kill your neighbor
Thank you Paul! i purchased a DPMS 20 inch AR15 about 5 years ago and right away bought a slew of ammo for it. When i got to the range i found the difference exactly what you reported here. i was a bit confused but am now enjoying the confidence that knowledge gives. i worked as a contractor most of my life and knowing the potentials and limitations of your tools is the key to using them to maximum effect.
@TheMetalGuy852 Incorrect. 20/10 is the correct term. You're seeing detail at 20 feet what someone with normal vision would need to be 10 feet to see. 10/20 would be worse than 20/20 because you're seeing detail at 10 feet what someone with normal vision could see at 20 feet. It helps to know what you're commenting about before you make the comment :)
best content on RU-vid! and for some weird reason he always has a video on exactly what I'm wondering about haha. thanks Paul. your the hero we dont deserve
The meat target is much more effective as a tool in ballistic performance over Ballistic Gel. I don't know what you have to spend on making one for your videos, However, it's worth every penny. when I shot High Power service rifle my common bullet was the 55 gr for the 200 Yard standing and sitting strings. 300 yard I would use the same bullet that I used at 600 yards. saved me a little money on bullets and the 55 grain shot just fine at 200. As always. Good video Paul. Dave.
Paul: i’ve been watching your videos for quite a while now but have never taken the opportunity to say thank you for your effort in bringing commonsense to the field of defensive firearms use. I know that you too have been involved in a conflict resulting in the lethal use of force and personally appreciate the commonsense approach that you bring to this aspect of firearms use for the legal preservation of innocent life.
The green tips are more expensive at the store I usually shop at but I realize the green tips do serve a purpose. I think based on this test I'll stick with the 55gr. Thanks Paul!
Pretty interesting. Thanks for this video.... Also, someone should “loop” the section of video where you fire the 62grainers into the dirt and turn it into techno dance hit... just saying.
Dude your channel is the shit. Every time I'm wondering something about a specific type of gun, or defensive situation, or type of ammunition, etc. you have a video on it covering it in meticulous detail. Woefully underrated but definitely one of the best firearms channels on youtube.
I do truly enjoy your videos Mr. Harrell. Shatner-esc pauses with just the right amount of dry humour. Compiled on directly informative data. Truly an enjoyment to watch.
The 55 grain M193 has the best all around when it comes to accuracy, light recoil ,lethality, and cost.It would be my choice to stock up on.A proven manstopper.
This is probably my favorite Paul Harrell video, as I reload for both 55 grain and 62 grain bullets shown here. Some years ago, I purchased 5,000 pulled SS109 bullets and reloaded them to 3,000 FPS with H335. I use the same powder for 55 grain loads as well. They both serve a purpose and do well.
Now this is why i like your channel so much. I just got out of the Army myself after 12 years, and i’ve never asked myself this really basic question between the two kinds of ammo we used. Thanks!
Mr. Paul does the most in depth analysis/experimentation on firearms and their ammo on RU-vid without spending a fortune doing it. And he gets the point across well. I’ve learned so much more from this channel than most others.
All good information, not just to compare the two bullets but to bring to light the effect of rifling/rate-of-twist and composition differences between the two...
This channel is full of the absolute best firearms videos I have ever seen, and this one is top five easily. Thank you Sir for your service and for making these outstanding videos.
Hello Paul Harrell. Thank you for another excellent video. Folks like you, Chris Bartocci and a few others are my go to sources for firearms and ballistics info in the real world. I look forward to your well done reviews and commentary. All the best to you from Florida's west coast. Take care.
Loved the 100 yard shots. The sound of those bullets flying past the camera reminded me of days once spent pulling targets in the "butts" on the KD range during qualifications. Thanks.
Those were some of the higher chrono readings that I've seen for the 55g, out of the 16". Nice! 5.56 55g is always moving a little faster, than the .223 55g. Looks like I need to switch to 5.56. I buy .223 because I have a bolt action in .223. And I don't wanna hear how it's ok to shoot 5.56 in a .223 chambered firearm. IT ISN'T!!!! If you are one of those people that think it's ok... Look up throat, lead, bullet jump, rifling, chamber...things of THAT nature. You have a lot to learn. The 5.56 cartridge has virtually NO bullet jump, before it engages the rifling in a .223 chambered weapon. Rifling instantly slows velocity, which in turn, increases the pressure of an "already" higher pressured cartridge. Too many RU-vid experts saying that it's ok. My face is ugly enough, without doing something that stupid.
@@jamiesloan5902 Why Have a throat Reamer Both 5.56 marked barrels had burrs the old SP-1 marked 223 passed 5.56 chamber gauge on first try. AR-180 had a little bur that took One twist to remove. so all mine will feed both safely.
Most if not all AR's on the market have both .223 & 5.56mm. stamped on them to let the buyer/owner know that both can be fired in the AR. As far as a bolt action .223 I would have to check with the maker of the bolt rifle to see if it will safely fire the higher pressure 5.56mm. rounds.
Very eye-opening! I worked at a gun shop during my college years in the early 80s. There was still a lot if talk about the tumbling rounds from an AR15 and even though I could have bought one at our employee discount, I never considered it. Why would I want such an inaccurate firearm? It wasn't until 1996 or 1997 that I learned of the whole rate of twist being the reason for the tumbling round and I finally bought my first AR. It's a Colt Sporter A2 with a 1/7 rate of twist. Sweet! This is the first video I've seen that shows the difference in steel core versus lead core. Thanks for sharing, Paul.
