- Ian Klemm, previous guest from some some of our most popular podcasts of all time in the Long Range series, joins Mark and Jimmy to talk all about barrels. Are these the most important parts of your gun? Why are there so many different kinds? Materials, fluting, twist rates, types of rifling, lengths, coatings, tuning, free floating, the list goes on and on! Ian discusses all these topics in-depth in the way only a mega-genius gun-nerd engineer could. Whether you’re looking for a barrel to complete your ultra-custom long range rifle or simply want to know what all the hubbub is around these things, this podcast is perfect for all you gun nuts!

Progressive twist barrel compared to drag racing: Too much power too early will spin the tires. Lowering power to let the tires hook then ramp in to full power.
Is there any reason why progressive twist rates couldn't be designed into a die to achieve it in a cheaper cold-hammer forged barrel??
You guys share such intelligent conversation, I feel like we should be awarded college credits for listening to the vortex nation podcast. Thanks for the time and effort you all put into these episodes, keep that good info coming our way!
We're working on becoming accredited ;) Thanks for tuning in, my friend!
Please have Ian talk about "Structured Barrels". I would love to hear his engineering comments and thoughts.
My 222 pencil barrel went from 1.5 Moa to 0.5/0.25 Moa since i put a huge and heavy SAI monocore suppressor on it!
Harmonics are the key to accuracy...
🖖🏻🇫🇷😎🇫🇷🇫🇷🖖🏻
Tuning the load to a specific time in the barrel harmonics just blew my mind! I had never thought of it like that. Incredibly informational pod cast.
Isn’t that what an “accuracy node” in a load development ladder is?
@@chipsterb4946 I have no idea
Well, now I'm even more proud of being from Wisconsin. Learned something new as I usually do in these podcasts.
I’m completely in love with this podcast. Thank you for sharing knowledge from a wide array of professionals. Really helpful for people who want to put in the research time to buy the right firearms and accessories the first time.
I wish we could see the visual aides
I want to see that free floated action rifle.
Years ago I read an article in either Rifle or Handloader Magazine on twist rates. The article covered the idea of over stabilization. Besides the potential of over stressing a bullet there is another odd symptom it causes. An over stabilized projectile will hold initial orientation (as fired) with the earth. This isn’t usually a problem with bullets, but can be a problem with artillery. Shells fired at a high angle, nose pointing up, will fly their trajectory with the nose pointing at the same angle all the way through its arc (if it stays aerodynamically stable). In artillery that would potentially mean the fuse would not ignite upon impact.
Steyr Mannlicher are the most beauty from the outside of the Barrelprofil as i was a kid my dad had 2 Steyr Mannlicher one in 6.5x68 one in 5.6x50Mag they where both really precise and such nice Rifles
Always great content. Thanks guys.
Awesome info guys! It was good to hear about all the different barrel fabrication types! Also, that double barreled rifle sounds amazing. I know I could never own one though--besides the price to purchase, I would be afraid to carry it in the field.
Ian is definitely a brave, brave man for actually taking that thing out into the wild! Lol!!
Good episode, nice to get a technical insight
That last barrel Ian introduced is unfathomably awesome
Great video I learned so much about barrels so big thanks.
What an awesome talk.
Wow! Amazjng video. Learned so much.
On the barrel sleeve & floated action, the Finns have been doing that for years to make sniper & target rifles with Mosin actions.
This was great. Thanks dudes
🤜🤛
Mark, I just figured out what your dad called it (the deresonator ring on a barrel) and now I cannot unsee what I have seen. Dang it!
It would be nice to see the pictures that you get to see!!!!
Hammer forged chamber FTW! Way to go DD!
Podcast coming up on progressive twist rate barrels? Or also maybe some reasons why two of the same barrels/twist rates would like completely different ammunition loads? Love y’all’s long take and ten minute talks!
I feel as if this set the stage for a Barrels - Part 2...?
Great episode!!
Thanks for tuning in!
You are forgetting increased pressures.... Extreme twists do increase pressures And impart more extreme demands on the bullet....especially jacket to core interface .... Lead has a lot of inertia.
I love that 30 30/28gauge!!
Barrel coatings! Talk about coatins? Are you able to send blued barrel to get nitrided? Or get a stainless barrel and send it for nitriding?
More reloading podcasts please, specifically in shotshells
Noted!
Also weight is NOT the driving factor in twist rate ....rather it is and indicator / symptom. The actual determining factor is the length . kind of. Any tapered bullet shape will be heavier in the base than the tip ..... "Thrown" objects naturally rotate to heavy end forward. To counter that you impart rotational stability ......the longer the bullet ( ie the farther the center of mass is from the tip) the worse this tendency is thus the need for faster twists. Also explains why round nose bullets ( nearly the same on both ends ) can sometimes work at heavier weights than can more pointy shapes.
Great video....
Great video, thanks... I'm sorry you didn't discuss cooling when you were talking about fluting. I've heard people say that fluting aids in keeping a barrel cooler by introducing greater surface area. This makes sense to me, but I would have liked to hear an expert talk about this and confirm whether or not this is true, and if true, whether the difference is enough to be meaningful. Of course, if anyone else has knowledge to share on this, let it rip... In my mind, if it does lead to significant cooling it seems to be a no-brainer that fluting would be superior on a defense rifle inherently... Just not sure if I am right though :-) **Edit: oops, I commented 2 min too soon...
Good one guys!! 😉
Gordon setters are the best!
I've watched quite a few of your videos over the years and just learned your located in Wisconsin. I'm in milwaukee and next time I'm out past Madison I'll drop bye your store.
So I should get a 1 in 7 for my 25-06 so I can stabilize those new 130+ grain bullets?
Great 👍 👌
Proof research barrels say their carbon fiber wrapped barrels dissipate heat rather than insulate it. I wish you guys had one of those barrels on the table!
I am looking at putting together my first prs style rifle. And want to shoot 25-06AI. Was thinking an M40 contour stainless barrel. Any advice or input on fatal flaws of that would be great.
Fluted barrels are stiffer / weight than unfluted. .......they also have a slightly increased surface area ..rumored to help with cooling.
It's kinda ironic, the barrel being the most important part of the firearm (regarding accuracy), yet people fail to understand it's also a "consumable"!
Barrels are tires.
Carbon fiber composite normally has a very low thermal transfer rate, but this is because the epoxy resin forming the matrix holding the fibers is a insulator. The actual carbon fiber's have extremely high thermal transfer rate. People think copper or aluminum are the best thermal conductors, but they are not even close to diamond or graphene both forms of carbon. As specialty aerospace resins become more affordable thermal transfer rates are going to dramatically increase for composite barrels.
I believe the Smith and Wesson 460 mag is a progressive twist barrel.
Please do a talk on everything about titanium vs steel barrels
Does it matter if it is right twist or left twist?
Question: Barrel thickness, is a #2 just as accurate as a #4 or #6? Specifically on a hunting rifle so not sustained fire
Cryo treated hammer forged is bout the most accurate barrel I've seen.
What would happen to the composite barrel if you tighten the nut while the barrel is hot?
Fascinating episode. I’d love to know who makes that cool carbon fiber barrel. Also, which episode did you guys talk about barrel tuning?
I know it’s 8 months later, but it was episode 57: Long Range 1003 - if you never ended up seeing it.
Curious about the manufacturer of the carbon wrap barrel you showed in the podcast great job by the way I found your publications on TH-cam a month or so ago and have been pouring through them as I travel for work I’ve heard a lot of good pointers on interesting ideas that I haven’t heard elsewhere in the shooting community keep up the good work
Here you go - www.bsfbarrels.com/ - and thank you very much for tuning in! We appreciate it.
Can you pull both triggers at once?
Longer and heavier bullets tumble so you speed up the tuist rate
Whats the best material? Stainless , chrome molly, ?
Who has the time to listen to the main point of something so simple . A billion people who love firearms and can't get a clear answer lol
Lol. You know how many people told me not to buy the 8 twist Browning X-Bolt .300WM because it's "too fast for light bullets"?
Yea that’s nonsense. I shoot 150 grains out of mine all the time and hit the target just as well as 180-200 grain.
I agree that whoever told you that got their stuff backwards. You want a fast twist rate for heavy fast bullets like the .300 WM. I needs the faster twist for stability. For just a regular hunting rifle, like a .308m you can get away with a 1:12.
223 WSSM whats the best twist rate for 75 grain hornady
Wouldn't gain twist change the angle of the grooves left on the bullet. So it would actually lower the BC of the bullet.... Doesn't sound like a good idea.
More on carbon please
Can someone just do a thermo test , with these $1,000 barrels mix it up carbon vs steel 🤔
Maybe I’m dumb but I don’t understand why Someone would decrease barrel stiffness…. Which increase barrel harmonics?
There's a lot of questions I have asked on these gun channels that never get answered.maybe they might be stupid questionsi don't know!
"Hemispherical trough" instead of flute was unnecessary lmao
Any Five-Seven or PS90 barrel manufacturers in Wisconsin?
As a metallurgical engineer, the current state of barrel manufacturing is very disappointing.
Please expand on that
@@ChielScape essentially every single barrel manufacturer uses 4140, 4340, or 416R. Those alloys are fine, and pretty cheap, but there are so many alloys that will perform better as a barrel than those alloys. Composite barrels like CF wrapped barrels or stellite lined barrles(a la FN) are steps in the right direction, but ultimately still do not fully utilize the vast amounts of new alloys and manufacturing processes that are around today. And before anyone says anything about increased cost, we're talking about competitive shooters here, people who replace a barrel every thousand rounds. I think they would be very happy to pay more for a barrel that lasts longer.
@@the1andonlySherlock Alright so what alloy would you suggest using?
@@ChielScape how much are you willing to spend?
@@the1andonlySherlock say money isn’t an issue, what would you prefer/recommend? Also, I’m fascinated by your field. Any suggestions to books to help me learn more on the subject? I know nothing.
Kids these days think they need everything and the kitchen sink attached to their guns. Barrels? None of my guns have barrels, don't need em. What else you got on that thing, an illuminated extended high cap ACOG?
I want that side by side 30-30 so bad I can't see straight
do the pre-tension barrels last a long time?
I did not watch the full video so maybe this was covered.
If you Google rifle barrels made from rebar you will see pics of a couple made here in Alberta.
223 WSSM
Lets look at the pic of the button and not you all chatting
The most important part of you gun is the safety full stop?
Also F class weapons systems can cost upto 35K depending on what barrel/ scope make and the rest of the components more importantly caliber, from .223 right up to the cheytac 406 round and even the .50 cal ,were talking about all customised parts trigger, barrel ,scope, rounds and all the other extra's if your going to compete in the world champ's. :) Barrels made in new zealand cost around 10K for a 308 cambered round, so just imagine a 406 cheytac round ?
Ian Klemm who is talking about how the barrels are made is an F-Class competitor with some championships under his belt. I bet he has spent some good money on just the barrel of his main go-to rifle.
Keep your digit off of the switch, point your weapon in a safe direction always and within most reasons, your safety doesn’t matter a single ounce.
A bar with a hole in it... you mean a tube?
Really would be better to see the things they keep looking at and saying cool
The most important part of any gun is the shooter 🤷♂️
Poor videography.
Dude you guys got to make this more consumable anything over an hour on one topic is kind of ridiculous I'm not saying short in the podcast just make clips people watching clips is what makes them want to watch something for an hour not the other way around
It's a shame that the boys have to inject their childish humor.
So vortex are lovers of conservation but the staff are willing to shoot critically endangered species...
You've lost my respect guys.
Can you elaborate on what you're getting at and where you heard this please?
