Thanks, but back when it mattered and I cared, I could never get any respect in job interviews for all the information I included on my resume about my skills with basketball, darts, archery, guns, Frisbee, etc. They would always just read it and then give me a strange look. :-)
I have a feeling you were real good at ball in college. :-)
“Just like THE PLANET”. (???)
This didn’t age well…. LOL!!!
You don’t live on a “planet”, Mr. Hickock, and here’s hoping you don’t believe in the fictional ‘Coriolis effect’
@@toberrdrawforc We do live on a planet, but it's not a "planet", it's a planette, as in the circular piece of a flat plane that everybody has been made to believe is a ball flying through infinite space without ever hitting anything meanwhile we see the same stars in the sky every single night all year round. The english language is all about trickery in the wording
Balance a basketball on his finger, Another thing Hickok can do that I can't. Damn this guy makes me jealous! haha!

eat clean and healthy hickok. we want you around for a long time. god bless. thank you for your time
Amen

8 years later, still informative
9 years now, and nothing's changed.
@@BionicDeathclaw I do have to wonder if hickock45 is still as deadly with a frisbee as he was 9 years ago.
10 years, boiiii!!!!
10 years, the most simplest to understand after searching
Just wanted to let you know how much we all appreciate what you do for this community. You don't have to make these videos, you don't have to go to the hardware store to pick up examples for the people that didn't know about twist rate, but you did. You are great person for this community and we appreciate all that you do.
FACTS !!!
Hicock45 , I have a gut feeling that you're pretty good at horse shoes, darts, pool and poker. After seeing the basketball, frisbee and archery I believe you're probably just a natural when it comes to those things. Love the videos!
+Steve Johnson that is one of the best comments on his channel!!
this is one well rounded man
You said it perfectly.
One of the smartest, funniest and most educational videos I've ever watched. Thank you so much, hickok45! :)
I know you did this 8 years ago, but thank you for still having it up and available. I am trying to get into long range shooting and I build my own guns. This video was a huge help in my understanding of twist rate and what I will need for a barrel for my 6.5 Creedmoor build. Again, thank you.
Pretty much one and the same, though. My six degrees from M.I.T., Harvard, Yale, and Vanderbilt, lead me to the conclusion that a longer bullet of a specific diameter will probably be heavier. :-) I think people who shoot a great deal and handload tend to just think of bullets by weight rather than length.
Mr. Hickok45, these types of videos are my favorite.
HICKOK45 FOR PRESIDENT on guy thats got my 100% respect.
Agreed
There's something to be said for his aw-shucks humility that makes him a pleasure to watch every time.
Not to mention his level of knowledge is right where it needs to be.
dayum hickok45 is a baller.
Afternoon,Sir. Genius example of your teaching skills with the bolt threads. Im 58 years old and learned from this vid. But I generally learn a lot anytime I visit the compound. Thanks for all you do for our sport and hobby.
You’re my GO TO person for gun info - just fantastic! THANK YOU for creating all of this wonderful and timeless content!
Thank you. You're not talking down to people you're talking to people. I love how you explain things.
What?
That stabilizing effect is called angular momentum
Centrifugal force you mean?
Hickok45, thank you so much for the basics videos. Over the past wish years I have been a casual shooter, friends would let me use their firearms on their personal ranges and they would always talk about things you've touched on in all these videos and I cannot begin to explain how happy I was when I stumbled on your channel. I learned a ton and I just wanted to say, as a beginner level shooter, thank you for taking time to do these videos.
THANK YOU for making a video on this, People who are actually looking into this are DEPRIVED of such a straight forward, & Extremely informative style. Thank you Hickok.
Shooter, Collecter, Sniper, Basketball all-star. hickock is truly a renaissance man.
thanks for the overview. I chose a 1:8 for my AR because it was middle of the road according to everybody's opinions. Very happy with my PSA build, I upgraded very few things, it doesn't look like a "desert storm" piece of equipment but it goes BOOM and hits a dime at 100 yards that's all I wanted it to do.
Hickok45 is a great teacher, I'm glad for his students
Pretty cool side note: when a bullet is fired down a rifled barrel, the barrel leaves grooves on the slug. Very cool to see this if you're able to recover a whole bullet after it's been fired.
MixBernstein yeah that's how tracing a bullet works. Every fireman(aside from shotguns) leave their own unique Mark on the projectile, the police use forensics to trace the slug to your firearm. And GSR on your hands and the firearm will confirm it's been fired recently.
RBabik Ii that forensic evidence, or rather what can prove that evidence is connected to any given firearm, can be quickly destroyed by damaging the rifling.
Called "Ballistics" I believe
Hickok you are a national treasure, and beloved PATROIT thanks for all the tutorials, God bless America!
probably the simplest explantation of twist rate ive ever heard , yet another fine hickok45 video
You sir are the Bill Nye for Firearms.
except he doesn't think that people that don't agree with him should be sent to prison.
f*** Bill Nye
He's not the Bill Nye. Hickok knows what he's talking about and lives in reality and is safe to be viewed by children. Can't say the same for Bill Nye and his "gender spectrum" invented DNA and invented qualifications. Also, I like Hicock and hope to be more like him. Be great if he dressed like Bill Nye every now and then though haha
Thank you for explaining this, i keep hearing people talk about this and i had no idea what it mean before. You made it very simple for a novice like me to understand. Big thumbs up
Concrete anchor bolt
Thank You Hickok45, I am new to guns and had no idea about twist rate or why I had grooves in my barrel. Awesome!! Thank you for thinking about us who are new to guns!!
Best nontech explanation of twist yet, the visual aids were great.
Excellent channel. Wish there was a way for decent and competent people to have this hobby in my country.
10 years later and still solid info!
I was so confused about twist rate.. And when people talking about that I just pretend I understood and agreed... But now I'm truly understand! Thank you!
I learn something new every time I watch your vids. I knew what a twist was for but I didn't know that 1:8 or any other twist rate meant one revolution per how many inches. Thanks for the knowledge.
I've stumbled through trying to explain twist rate to friends before and never though of using bolts as an example. Thanks for posting because it will sure help the next time someone ask me about twist rate, if I happen to have some bolts handy at that moment. As usual your video earns another like from me.
This was very interesting and knowledable. You explained this better than most. Thank you and have a great day...
brother Greg, you are a man of many talents.
BTW, if no one has said it yet, big screw you bought is a post-installed screw anchor used in concrete and masonry. Used for applications where a pre-installed anchors (like when bolting a wall of a house to a foundation that has bolts embedded in the concrete) aren't present. Great vid guys.
I love your teaching videos. Your skill as a classroom instructor really shows in this video.
The 1/2 inch diameter bolt with the blue tip is a wedge-bolt(maybe even a Hillman Wedge-Bolt). It's best use is for bolting-down each corner of your gun-safe to the concrete slab in your bedroom-closet floor. Drill a 1/2 inch diameter hole for each bolt with a wedge-bit and use an impact-wrench or 1/2 inch ratchet to bolt that sucker to the floor.
Hickok is like the granpa who knows everything about guns for hundreds of thousands of people!
In other words, a 1:7 twist rate is MORE twist, than a 1:9 twist rate. Because it only takes 7" for the bullet to make one complete revolution, as apposed to 9".
basically a 1:7 is the best all around twist rate and its what the military uses. It will stabilize any grain 5.56/.223. 1/8 and 1/9 will not do so well over 69 grains.
@@VanguardXwhat's the lowest fps a .223 can be shot at and still be able to stabilize?
@@airgunsofidaho4886 2000ish
I always learn something new when I watch your videos.
Forget school. I'll take science class with hickok anytime.
You are correct. Most folks think it's the weight that is the determining factor. It's length. I learned this using Barnes bullets. They are copper and longer for a given weight than a lead bullet. They require more agressive twist rates than lead bullets of the same weight. Also seating depth is a factor, but I digress...
Thank you so much. This video is just what the doctor ordered! I am in the process of building a custom AR and I needed to pick out the twist rate.
Anyone else hear the James Bond theme song at 2:47?
lulz
Hahaha! I actually listened for it! DUH!
Brandon Campanile He definitely missed a opportunity there XD
Brandon Campanile beat me to the punch!
totally 007
you and a basketball......you never cease to amaze me. Impressive. American Hero.
Very well explained, i knew where you were going the second you pulled those bolts out. Who knew youtube had well thought out smart videos.
What?
oh hickok45 went to college in the 60's... that explains everything.... haha
Great personality and teacher. I have learned more from you than anyone else. The most important lesson was....trigger pull. Wow.....you really taught me how to hit the target well. Keep it up my man. Need more just like you.....thanks very much!!
I've got a .54 cal. flintlock with a 39'' barrel and the twist rate in my barrel is 1 in 65''.The barrel is made to shoot patched ball.It takes a much lower twist rate for the cloth to engage the riflings.
yes, that makes sense. there are slight differences in bullet weight and length, i mean incendiary, a/p and stuff like that, but more or less they are the same. thanks again.
Excellent synopsis of rifling and spin (gyroscopic) stabilization.
Needed rifling twist is determined by caliber-to-bullet length & bullet center-of-gravity. For example, a 2-caliber long .357 bullet will stabilize best with a 1:27" twist, while a 3-caliber long .357 bullet will need a 1:18" twist. A 2-caliber long .45 cal bullet will only need a 1:34" twist.
A nose-heavy, hollow-based bullet, such as a 58 Minie, will shoot very accurately in a slow round-ball twist of only 1:72".
Thank You "hickok45"! This is the best layman version of clarifying twist rate ever! Simple and to the "Point" clearly! I now understand what twist rate is all about. I didn't realize you are or at least once were such a good basketball player in your younger days, :-).
Oh Yeah, Life is Good!
The only problem with your demo of showing off the lands and grooves comes in if someone looks at a barrel with polygonal rifling!
Another great video Hickok. Thanks again.
Hickok is nothing only a sniper on the range but makes it absolutely rain on the courts.
*WELL SAID MR. HICKOK 45!!* *AND HEAVER BULLETS NEED MORE TWIST RATES TO KEEP IT IN STABLE IN FLIGHT AND CAN HELP IN DISTANCE, SOME WHAT.*
Now I can explain to my brother why the 1x7 twist is better than our 1x9 twist ar-15 barrels. Thanks for the info sir.
thank you. never to old to learn.
THE Best explanation of twist rate. Perfect ! Thank you
Another good example is the fast pitch and knuckle ball in baseball. The fast pitch is known for the accuracy and speed while pitching to the batter where as the knuckle ball is thrown to try and throw the batter off. But your examples were also very helpful!
The twist rate, like he said, depends on the weight if the bullet. A lighter bullet however will have a lack of inertia so when it reaches a certain distance it will have slowed down to the point where the rotation takes over and it will curve off, sightly at first, gradually more. I hoped this helped someone.
Some newer shotguns have rifled barrels as well, but those are designed to primarily shoot slugs and certain specialized shotgun ammunition.
I know its not perfect but you know what's really impressive is the time between cut frames, you know your stuff so well you can pretty much improvise things. You're a gun nut!
Well done hickok45, I think you answered a lot of question's for a great many new shooters and spelled out a few things some of us seasoned shooters didn't know as well. Thanks for a video, that I don't think has been done before on youtube.....
Wow, A Hickok45 video with no shooting! Sir, you make the most useful and interesting firearms videos on the tube.
My brother and I were out shooting one day and he put close to 1000 rounds through his Walther P22 in a very short period of time (the barrel was so hot that lead was dripping out the muzzle). His grouping on a paper target went from tiny little .22lr "holes" to elongated "tears" because the .22lr ammo began "tumbling" caused by the loss of rifling in the barrel as lead built up in the grooves (accuracy dropped way down too).
@StaticPulse83
Good question. Actually 5.56 is your bullet. Ideal Twist rate for a bullet depends on the weight and shape of the bullet. Not whether or not if it is a .308 or 5.56.
1:9 is a a little over the middle twist rate for a 5.56.
The more middle would be a 1:8 twist rate. This twist rate works well with any weight (in grains) of 5.56mm
Like Hickok said, the heavier and more pointed the bullet such as rifle rounds the more twist you need.
The lighter and more rounded the bullet such as p
Of course I would search this and find good ol' hickock45. What a legend.
This video reminded me of that troll that tried to explain to you guns were called guns because they were smooth bore and we called them rifles because of the rifleing in the barrels. Thanks for the video.
I think most of us knew the effect of twist rate, but that said great examples and nicely produced. Excellent video for the young and inexperienced just coming into the shooting sports Hickok!
You must be an awesome teacher. Wish I had at least one cool teacher back in grade school.
In Europe we call this dynamic feature "angular momentum" as force per dimension, weight and angular speed (not twist, but spin), given by objects that rotate and more heavier they are (plus aerodynamics, and so on), will tend to keep liniar trajectory as so. Now we go in high balistic science. Never forget Newton's first law. As more mass, more power is needed to change dynamic status. Nice presentation, Mr. Hickok, anyway. Sorry my English.
The bullet spins, the rifling has twist, that's why we use twist, because the barrel is the platform.
a fast twist rate accelerates barrel wear and can also lead to overstabilization where the projectile tends to maintain the orientation it held when it left the barrel instead of pointing in the direction of travel as it follows it's ballistic trajectory (in other words, too high a twist rate can cause it to tumble or keyhole at long distances).
Hickok with sick crossover!
No doubt!!!
Very well put into layman's terms unlike most of the benchrester lingo and jargon out there. Thanks for informing the masses Hickok!
Hickok45 is an awesome teacher.
Sir, it's weird watching a video of yours without seeing a gun being fired or shown.
But still helpful. Thanks!
That boat tail hollow point bullet. DEADLY
that other bolt has a nut for it. It is for concrete work so the threads don't get gummed up with dried concrete particles. Its for holding forms together.
I did not know the detail of twist rate. I knew there were different amounts, but never knew what they meant and their use.
I learned two new thing today so far. A tip from a long time photographer and here on Hickock. (firearms experience? shooting since 18 and service with the USMC-see coffee cup). You never stop learning.
Hickok has MAD skills!
No wonder your such a personable guy...You went to college in the 60's...peace love and happiness. Great video, you are an excellent educator. You can teach the phone book and make dummys like me understand it!
i love that you are dedicated to educating and having fun
Thanks for the info. Longer bullets make sense. I did not consider the drift from over rotating.
I had a grasp on this already but this is an excellent way of explaining the concept.
Well, now a fast twist rate would cause any weight bullet to be more stable, I suppose, but it's more essential for the heavier / longer bullets.
Also, at longer distances, a higher twist rate will stabilize the bullet better than a slower twist rate on a heavy bullet. Cheers! Good question :D
This is the best Eli5 I've ever watched thank you.
The spinning basketball example was perfect, thanks for sharing your yard with us, hehe
It comes to pretty much the same thing. About the only way to get a heavier bullet for a given caliber is to make it longer.
never heard of twist rate - whenever i watch a video from you, i learn something new :)
Thanks Hickok and Mikey, I had an idea about the spin but this clarified it for me. Good Job.
I can't get enough of Hickok's slow motion laugh. Epic XD
The correct twist rate of a rifle makes it more accurate with a bullet that has the right weight and ballistic coefficient for this special twist rate. It will be less accurate if you use different bullets (heavier or lighter, or even with different bullet geometrics), so you should ever use the same bullets if you like to have top accuracy.
One other thing which is commonly unknown is that when a bullet leaves the muzzle, its very tip still is kind of "wobbling" (miniscule, of course) and gets perfectly stabilized only after it passes a certain distance using the air resistance to do the trick.
This is a fact found out by German scientists during WWII. The consequence is, for example, that a bullet shot from a K98 gets its maximum penetration ability only a few yards after leaving the muzzle. This is especially true for "hard" targets like steel or such (since using the tungsten core ammo of WWII German soldiers were able to penetrate even the steel armor of early light tanks, like seen in Poland).
Means, if you shoot something with the muzzle directly on the target, the bullet will have less penetration than giving a few yards distance to perfectly stabilize it.
With revolvers or pistols, the twist rate is of no such significance.
John did a good job hiding that smudge on the lens mid scene.
