- Confused about rifling twist? Wondering if yours is correct? Not sure what twist rate is best for you? You are not alone! Many shooters today are faced with the same questions, and get far too many bad answers that leads to bad choices for their personal shooting requirements. GunBlue490 will explain every important thing that you need to know about selecting the correct twist for your rifle, and will demonstrate how to easily measure your rifle's rate of twist! Learn why the twist in your factory gun is almost certainly the correct one already.
I have owned and shot firearms for over 50 years, this presentation is the most complete explanation covering both the theory and practical sides. I just subscribed a few days ago discovering the channel quite by accident , what a treat, no BS , NO HIP SLICK AND COOL , just cogent well presented discussions. Thank you.
yonny1954 and no annoying loud music or swearing
@@ivobiancucci4528 Yes, I hate loud obnoxious intros and exits that wake the dead. I complained to presenter that I really liked about his loud music, that added nothing to the content but woke my wife. His response, "screw you". OK
yonny1954 Yes, he's the best. No rock music or shoot 'em up intro. He's not a slave to any brand. No infomercials here. He does need some tattoos and one of those Robert E. Lee beards though! LOL.
Captain has changed the way I shoot, changed the way I reload, deleted the way my wallet gets spent on useless junkie products, the way I clean my guns and preserve my guns, ALL for the better, with each of his videos! What he knows and shares will carry on and on. The truth is the truth! I'm very grateful to him and commenting fellow subscribers.
Its a treat that he posts on youtube also. Most of these salt of the earth good guys dont want anything to do with tgis platform.
Love your channel Captain. You've got this 34 year old hooked on your knowledge.
Someone that wants to share his depth of knowledge without any strings. Thank you.
I'm 65-years old, been around firearms all my life, and learn so much more about firearms from your channel. Wishing you the Best and Thank You. Alaska John
Been making barrels for 42 years...and I can be buffalo'd by all manner of things. Rifle barrels aren't one of them. Really nice to hear a well spoken, well informed gent who lays proper information on the line. Ya' nailed it son..!!
There are SO many "gun experts" out there who are so grossly misinformed, and then pass these misconceptions on to others...its sickening.! I watch many of these videos scheptically..waiting for the nonsense to start. YOU are a breath of fresh air..!!! A well informed gent who properly phrases "gun speak". Definately not your first rodeo.! Thanks for helping the average neophyte out there. I've dealt with far too many who are genuinely clueless. Lets hope some of the info you're imparting sticks with a few of these guys.! Keep it up..! Made me smile......! Regards...
Thank you for that. God bless.
Are you an old gunsmith.?? You've done your homework. Ex- military..? Just curious..?
This man knows guns inside and out,thank you sir
The whole time I was watching, Proverbs 18:15 was going through my mind which says, "The heart of the prudent getteth knowledge; and the ear of the wise seeketh knowledge". I know where to come when I seek firearm knowledge! Thank you for giving your time, knowledge, and wisdom. I have learned more about shooting equipment from you, than anyone else. That also goes for my wife and my daughters; they feel the same as I do! May God bless you in abundance!
I've been into firearms about 50 years, I still learn new things every day about the physics of the bullets.
There is such beauty and elegance in mastery. Absolutely beautiful how you masterfully articulated this topic. A true master.
Hello Sir,
Thank you for your gift and your time.
Nothing better on a Friday night than putting more valuable Gunblue knowledge in my memory banks
Take care
Rick Mansberger
ps. Hi Benny
Someone who knows what he is talking about ,no stupid background music /noise and strangely an American who talks on subject and not a sales spin ,..refreshing and others I hope will follow your example .
I appreciate your videos because I learn so much. They are in a class by themselves. Thank you.
I'd send you money for the knowledge you've shared with us; if I knew where to address it..
This man is a encyclopedia of firearms. Learn much from you.
I want to hang out with this guy. Hero level knowledge.
Thank you for making the complex still complex, but understandable! I appreciate the effort that you put into your videos, and your ability to make me understand the processes, without just telling me what I want to hear. Like me, you're old enough to remember the Memorex commercials with Ella Fitzgerald. You are the real deal, you are an original! Too many people are running around the Net repeating what they hear with no understanding of what they are talking about. You're an educator! Please keep up the hard work! Your efforts are not going unappreciated. Thank you and......well, you know!
Wow that was an excellent presentation! I really liked that it had no annoying music as some others stated. Thanks for showing how to measure the barrel twist too. It was all interesting!!!
I call this applied engineering which absolutely is more practical and truthful than other methods.
Nice to have a subject explained concisely with an eye towards practicality. Thank you sir.
Love your videos. Thanks for producing them.
Amazing - you appear to just switch on the camera, stand in front of it and give an incredible, fascinating lecture without notes or prompt - as if you were a college Professor! If you haven't written a series of books on shooting, you ought to seriously consider doing so. Many Thanks & Best Wishes from the U.K.
I've been watching you for a good long time now and occasionally return to selected videos such as this one. You are a treasure and wealth of knowledge. I appreciate also, you are a man of God and your morals are consequently golden.
Gotta love this guy. I wish I could personally go to the range with him. Please keep them coming. Cannot help but learn something each time. Thank you.
Great teacher...one of the most valuable and educational channels on the whole of youtube
This is one intelligent gentleman!
You have answered every question in a half hour that I've ask others about in the last 20 years.
I was literally glued to my android listening and taking notes.Thank god I found a channel that was recommended to me by Utube. You have a new fan. God bless.
What a brilliant video!!! I could listen to this guys voice all day!
Dang! How you don't have a million subscribers is beyond me, thank you so much for sharing your extensive knowledge and expertise, it is not only valuable but captivating in its interest. Salute.
This guy is the real deal. No BS and a wealth of information like no other I've ever heard. Like going to a "firearms university". I have been around guns for 50 years and have learned more in the last few months than I thought possible. These videos should be a requirement for anyone working in the gun or ammo department in any retail store. A true learning experience and a pleasure to listen to. Thanks, John Torian
well all i can say is to bad i didn't find this guy years ago when i purchased all the parts to build my AR 15. back then like he said most everyone was saying 1:7 twist was the way to go an maybe it still is for a 16" barrel shooting 55 gr. and 62gr green tip 5.56 ammo. wish i knew now. i hope it is as o'm not going to go and buy another barrel just to get a 1:9 twist rate or something like that. anyway it was really great to listen to him explain twist rate and what happens to bullets this far out or that far out. best thing is i could listen to him talk about this stuff all day, thank you sir.
ive been shooting for years and have shot many different calibers. This man knows his stuff!!! i find myself looking forward to all his videos. I'm learning so much from you sir and i thank you!
Fantastic information , will recommend this video to all my friends. Wish I had your teachings when I first started learning to shoot. You are very much appreciated and thank you.
Last time I heard a guy like this, I was talking to a gunsmith who had been building, repairing and shooting firearms for over 50 years. Thank you, sir.
God I love this channel. Learning heaps. Thank you sir.
Gunblue490 thank you again for another very informative video sir looking forward to more great advice in the future
Do you know how to message him. I've done it once and he was very quick to contact me back but I don't remember how.
Robert Rich Click on the 'About' tab on this channel. Directly next to the little flag symbol is the message icon.
Like??
asking pertinent questions and you'll learn even more....
So polishing out all those scrapes down the inside of my barrel was bad? Thank you again for sharing your knowledge and wisdom.
This is by far the best explanation of practical aspects of rifling twist rates I've heard.
GunBlue490, I asked this question of you regarding a .243 in another video, and after you answered, the implications of shear force on lighter thin jackets were clear to me. My Ruger target .243 with 1:9 shoots better using a 70 gr than a 100 gr, but only marginally so. It would not affect a hunting situation should a 1:10 be present in a hunting .243 rifle. I think, after reading many forums the last couple of years, you are exactly right in the description of use for .223 and heavier, longer bullets. Also a trend is now to the 300 blackout where individuals are shooting subsonic 220-240 grain bullets and looking for a way to stabilize these heavy bullets. I have noticed questions on the forums even regarding subsonic or reduced loads for .308. Just as you mention Remington changing the twist for the hunting applications of .243, perhaps the trend for the 300 blackout group is influencing the questioned need for faster twist? Your answer is spot on....individuals should ask themselves what their intent on owning the firearm is. Thanks for the explaination!!!
I enjoy learning from your experience. Its a pleasure to have someone explain complex subjects without sounding complicated. Thank you sir.
For those extreme ranges that don't apply to most shooters it is possible to have to much gyroscopic stabilization relative to aerodynamic stability because it fights the bullet aligning its self to the relative airflow as it gets late in the trajectory arc. Very corner case but it is there just the same
I understood more of this video. I may still have to watch it again before I try to move forward on other parts of the rifle.
Thank you for sharing your knowledge on firearms, I have learnt alot from you and I will definitely share your knowledge with others. Thank you sir.
What a wealth of knowledge this guy has! Loved every word.
All true and correct however, a 125 SST loaded in a 308 under 4895 (light load) or Varget (heavy load) are killers on Texas Whitetail out to 200 ish with a 1/10 twist.On the other end, I've been successful with 220 interlock round nose under Varget out of the same rifle while on in your face pig hunting adventures in the thick east Texas bottom lands.Gunblue and Hickok are by far my favorite you tube channels. Thanks for all ya do.
Outstanding video. You really know the art! I love learning from what you have to share. Thanks a ton. This is a video worthy of watching about nine times!!!
This guy really knows his stuff! Thank you sir
Thanks sir, America stands tall thanks to men like you who have created its legacy forever. May God bless you.
Great information as always! We love seeing your channel grow day by day. May God continue to bless you and this channel. And so true about what's popular. In general we typically don't do trends whatsoever. We'll see you on the next one...
Your knowledge is vast. Thank you for sharing with us. Comes in very handy for us hand loaders.
thanks for the tip about squaring the target to the shooter then checking the circularity of the bullet holes. I'll do that very thing when checking the tuning on my bow or crossbow setup, but it never occurred to do that same thing to check a rifles "tuning". good advice, please keep it coming!
I'm an average type of guy and I've never really given any consideration to the rifling twist other than the actual condition of the lans and grooves. So thank you very much for confirming my belief that to us average shooters it really doesn't matter. Best regards.
This is the absolute best gun channel on UA-cam. I only discovered your channel yesterday and have already watched several of your videos. Reminds me of listening to lectures in college. Thank you for your service and sharing your knowledge. I, for one greatly appreciate what you do. Subscribed
Great advise as always. I have buddies that chase trends like crazy. For example if it does not say magnum on it it's just weak. Instead of waisting my time trying to explain it to them in just going to start sending links to your videos. Thank you for the time and effort you put in your videos. God bless!
Sir, so much knowledge sharing and in the most didactic way, I learn so much listening to your detailed explanations. God bless you too
A fountain of practical knowledge, superb instruction and guidance
Thank you for the information you share.
Your are a wealth of information and knowledge thank you for always sharing with great videos
Thank you for the clear explanation! You should use the 220 Swift as an example, when first introduced by Winchester (1935) the factory load was with 46-48g bullets so the twist was (and still is) 1 in 14". I have a Ruger M77V with 26" heavy barrel and would love to shoot some of the 70g+ high BC bullets for longer ranges...but they won't stabilize. The small .223 Rem will handle the big bullets but the giant Swift won't.
Excellent, thanks for your time and effort.
Thank you. Your video cleared up several of my problems. Great video
Such knowledge here! GunBlue490 is a treasure!
Terrific, educated, experienced information and presentation.
Best quote from this "slow, luxurious twist"... awesome. 15:55
Thanks to this I have a fantastic new way to view my 22-250.
Very good information put in a way that we all gain practical application knowledge. Also if your a hand loader most loading manuals use standard twist rate barrels as the basis for their loads for a particular cartridge.
Wow. The information in this video is unbelievable. Thank you.
Thanks for the information. And for putting in a simple way that it is easy to understand.
Great video on twist! Especially the example you provided with the 22-250, typically having a slow twist, yet providing extreme accuracy with short 55 grain bullets. Regarding high velocity bottleneck rifle cartridges of .22 thru 25 caliber the fastest twist intended for longer bullets doesn't always determine accuracy, bullet integrity and even stability in some instances. Thank you.
Very informative thank be you.
Great info! My father likes using heavier bullets when hunting big game for stability and humane kill, plus Gotta be loaded for bear, I recently built an A.R. 15; 16 inch with a one and seven twist because I figured faster twist would be better for most 5.56 and 223 loads. After deer hunting most of my childhood with a 30 cal rifle all A.R. 15 loads looks small to me
If the diameter and the density of the projectile does not change, the more mass you have, the longer the projectile.
Longer projectiles are more likely to tumble because the center of gravity is further from the point of the projectile.
This means more revolutions per second are required to get the proper gyroscopic spin, but increased velocity increases revolutions PER SECOND.
The other means of creating more revolutions per second is to increase the twist rate for the same distance covered per second.
A .223 with 60 grains with a velocity of 2000 feet per second with a twist rate of 1:12 will turn one rotation in one foot at 1/2000th of a second, yielding a RPS of 2000 using 533 ft/lbs of energy.
A 22LR with 60 grains with a velocity of 1000 feet per second with a twist rate of 1:6 will turn two rotations in one foot at 1/1000th of a second, yielding a RPS of 2000 using133 ft/lbs of energy.
They will both have the same amount of gyroscopic stabilization with the same projectile mass, but at different velocities.
A good example of this is the Aguila SSS 60 grain subsonic cartridge out of a 1:18 barrel. It will begin to tumble the moment it hits resistance. With a 1:7 twist rate, it is stabilized.
A .223 would not tumble with a 1:18 barrel because its velocity is near 3000 fps.
REGARDING "TOO MUCH RPM," the bullet is sized to the grooves; NOT the bore. A .357 has a .350 bore. So the bullet gets swaged to the bore size. This makes sure the bullet "obturates" or fills up the barrel to seal the gas pressure instead of wasting energy. The barrel does not give, so the bullet must. If the bullet metal is not soft enough to swage, it will fragment. It is NOT to much RPM or even pressure. It is far too little give in too short a space of time, not gyroscopic centrifugal force.
Thanks for sharing your knowledge of twist rate and how simple it is to get twist rate..Good stuff...
Novice gun enthusiast here...Thank you for this VERY informative tutorial!!
Always great information.
Cut rifling, Button, other?? Barrel harmonics? Bedding (how/where), PSI and barrel wear, Penetration not a function of speed but bullet design, rise of magnum Craze, why 30/06 is the best (oh boy). Well you get the idea. Would love to hear your views on these 😊
I like listening to you because you remind me about an American virtue, perhaps it is thriftiness, perhaps it is frugality, perhaps it is modesty, or being economical, whatever it is, it is avoiding hubris. We don’t need to be arrogant we don’t need the armor of King Saul. It’s OK to be King David, and I’m sure eventually he had some armor but I think it was appropriate and tailored to him and his needs. It wasn’t to much or too little it was just right. If other people are doing it as the common bread and butter, it’s probably because it’s a good idea, at least when it comes to technical stuff like this.
Great video. Thanks for sharing all of your knowledge.
Thank you! I always learn something from your videos!
As always a great dissertation, thank you.
Thank you for sharing your knowledge. This is one of the best videos I have seen on this subject matter.
Thank you for your dedication also this particular subject is of interest to me and I watched a program and also saved it thank you very much sir and God bless you✝️
Im a new subscriber! And have been learning a great number of things from your content. I live in NE Washington state. With nothing else to do besides watch it snow .And am new to reloading so thank u!
Great Video!!!
Thank you for the education Sir
VERY INTERESTING INFORMATION,NICE AND EASY
You need to write a book, as well as a reloading manual with your favorite recipes. I would be more than happy to pay for such books from you, and I'm confident I'm not alone.
Another wonderful video. Thanks a lot
My old (i purchased it used in 2017) Savage 99E chambered in .250-3000 tends to drive me just a bit nuts when it comes to bullet weight and type/design v powder charge v rate of twist. I love the rifle and I'm fascinated, maybe even a bit obsessed, with the cartridge as it SEEMS to be every bit as "good" as any .243 and many .270s I've had the occasion to shoot and/or hunt with. I've aware of the, sort of messed up, history of the round but I've accepted the challenge and hope, during the 2018 deer season, to make it my primary deer rifle while keeping my shots to around 200 yards at most when firing 100grn JSP rounds. I also plan on using the rifle and cartridge combination to thin out the coyote population when the opportunity presents itself while using the same ammo as I intend to use on deer. Having said all that, I'm a tad confused, thanks to some conflicting information I've found in print and online, as to the "best" bullet weight, design, and rifling twist for the .250-3000/.250 Savage. Since I have no plans in this lifetime to hunt anything bigger than South Eastern whitetail deer with my old Savage lever gun could you possibly suggest a "every man's" bullet and powder combination that will be usable, and dependable, on both deer and coyotes? If you do not feel comfortable providing such information online I completely understand considering the world we live in today. Thanks for the video though it's a year old now.....And I have no idea how I missed it the first time around. Take care and keep great videos coming!
Try a 25-06 off the shelf with off the shelf ammo and you will be surprised how it meets your objectives, and remember that even a key-hole round kills. Precision is repeatability such as a tight group several inches OFF target, but accuracy is hitting the target even in a shotgun pattern, but ON target.
Full of firearm knowledge and wisdom! Thanks so much!
Sir, your presentations are akin to an University Course. Clear, informative, precise.
Awsome video I learned a lot of info thank you. I do have one question though. I have a Christensen Arms mpp .308 with a 12.5'' barrel and a 1:7 twist. I purchased the Hornady CX 180gr bullets but wondering about a powder and charge. I'm thinking Varget powder. This is for an Elk hunt. I know my distances will not exceed 300 yards but that is ok as I am a archery hunter and tend to see more Elk at 40 to 100 yards in the thick trees. What are your thoughts on this? Thanks
This guy is a legend
Great video, you clarified a whole bunch of things for me there
In my opinion the Marlin 1894 44mag. at 1-38 rate of twist is too slow, 1-20 would be much better. Especially when shooting 240gr. bullets and heavier. THANK'S
for all the great videos.
The mrpete222 or "Tubalcain" of firearms
I mean that as a top-tier compliment.
Because it is.
Love your channel! I'm so glad i came across it! So interesting! Thank you sir!
Excellent information Sir !!
Funny thing is you have an ad before your video for a super duper high tech scope with wifi, no less, and you are a back to basics Weaver K series guy!
Another very informative video.
Thanks.
Please think about doing a video on issues with some Rem 700 trigger problems.
Concerned about safety problems, I'm sure you know what wete talking about.
Thank you so much for this. Ties in very nicely with with my last question on one of your other videos about heavier bullets being happier in my 308 remington 7600 (22", 1 in 10"). Really appreciate this video.
Well explained, Sir!
Excellent presentation . Congratulations.
Thank you for sharing your knowledge.
if you have an unstable bullet you may find one or two making profile holes in your target. My mod 70 Win in .223 is only good with 55g and under. Surplus Colt carbine with 1:7 chrome lined bore can spit out about any weight.
Sensational and very well put. I Had no idea that it works like that. Excellent thank you
