- So i get asked this question a whole lot. One of the more popular questions out there for the guys who get into shooting cast bullets or slugs. And it matters a ton because there are so many variables when it comes to airguns and airgun barrels. Hope this video answers the question of, "how do I slug my barrel"?

Thank God I found this channel.
I had heard SG mention you numerous times. But I was looking up " Too fast for you ".
I couldn't find anything. But when I just looked up "how to slug a barrel " I saw your channel. This explained it all.
Liked and subscribed. Thanks brother.
God bless you.
Thank You! I had no idea what it meant to slug a barrel. The vision I had wasn't anything close to what you just did!
Thank you again for all of the info that you share!
Sir, you are an exceptional instructor! Me guess is that you learned this in the military. Your demeanor and the way you handle yourself is special. You are my new favorite Utuber!. Please keep the videos coming.
Thank you man! I really appreciate the way you explain it to these guys from the Marine!
Dame good information for the slug fans out there 2F...you definitely got this down to a science my brother. much appreciate you and your wisdom Mr miyagi...awesome tutorial brother! 👍👍🇺🇸
Whats up Will? Thank you brotha and I too enjoy what you do. Your videos are very positive and informational. keep doing what your doing
I do appreaciate this sir. Can't wait to try it.
Great information
Love the no nonsense presentation
Another great vid Cedric! Thanks for sharing!
Great video! I’ll be doing that with my slugs now!
Well told and this is generally true for some barrels. That is why Altaros offers its ATP in the range of 0.01mm. But we found that shape also depends a lot. After changing the shape of the bullet, the barrels, which liked a projectile with a diameter of 5.49 mm, were able to work even better at a diameter of 5.52. This is a secret that most airgun and major manufacturers do not understand because they do not manufacture airguns and slugs at the same time. We can make slugs even after 5 micrometers in diameter and you can tell the difference in accuracy in a M24 airgun.
Very good info and you are so right. There is a LOT to achieving accuracy. You can be the best shooter in the world but if your gun and ammo are not shooting accurately, you won't get good groups. Shooting is a science as well as a sport. There is a LOT of science to shooting.....................
Great video! Thank you for sharing this information. I would love to see a few more videos about this.
Ok, at some point in the near future i can do that for you
@@Tofazfou 10 month no update about this,. :)
Well done. Good refresher for some of us
Your welcomed Frank. Thanks
Thanks Cedric, glad to see you touching on this. Back in the days of the rapid and then the talondor .257 I watched everything there was to learn and followed the 'yellow' forum. I now shoot an impact with a custom slug barrel, great for plinking cherry tomatoes at 130meters 👍 not quite soda cans at 400+ yards though 😂 👍 👍
Jay sir, I thank you so very much for sticking with me for so long. I means the world to me. Your comments and dedication show me that I am not doing this in vein. Thank you!!!
BTW, hitting a cherry tomato at 130 yards is nothing to scarf at and just might be harder than cans at 400+ yards. A cherry tomato is very small and at 130 yards, you might as well be shooting BB's off of golf tees at that range....lol! Believe me, I have a lot of respect for your shooting ability
Never seen it done before👍. Thanks for the lesson.
Your welcomed sir
You are the pioneer of slugging in the world of .17 👍
Just found your channel, judging by 1 comment that "you are the pioneer of .177 slugs" I am in the right place. Just purchased my first pcp, a .177 Nova Liberty with the intent to investigate slugs.
Go'on ahead professor Ced! Great video instruction bro. Very important info that all should learn
Much appreciated Bro. I know of all people, you understand and appreciate info. Thanks for tuning in
Always great info. Hope all is well. Stay safe and stay blessed.
Thanks RC. I'm getting back into my "TUTORIAL" videos. Hopefully i keep putting out useful info.............
Great video as usual, thank you for all the info
Thank you
This really helped me.
Thanks brother.
God bless you. Liked and subscribed. 👍
Thank you very information love the way that 172 look love the wood on it
Thanks MR C. That lil gun is sooooo fun!
You give me so many ideas Evey video I watch very nice stuff I done some build similar to some of yours. Great work by the way. my only complaint is nothing in air guns is cheap and hard to find parts made correctly. Definitely not for most people in less you have a lot of time and money. nothing to do with you just have to put it out there. I still love it. definitely wouldn't mind dropping a couple of varmint with you one day in the 805 👍👌✌️💯
I was told by roach Creek that.0005 to.001 over groove diameter is perfect. Instead of using a brass punch I just use a short piece of wood dowel to start the slug from the breach end of the barrel and then use a longer dowel rod to push it the rest of the way. I know that I'm just being over cautious but that's just the way I am
Thank you for this!
Hello. Long time ago I've been testing .223 Remington barrel in Kral Puncher One T airgun, 110 FPE. Twist rate was 1:12 inches, and best slug for these set was 5.7 mm RWS. Custom 55.5 grain slugs was accurate to 200 yards, strong wind was not gamechanger when I mean Cola can at 170 yards.
In my opinion most airgun barrels need two things to be usefull for slugs. First is fast twist rate, second - steel hardness. Hardness is guarantee better slip for slug and clean barrel.
Ok, now that you have 'slugged' (measured) the precise size of the bore, how do you reproduce slugs to the PERFECT diameter?
Thank you, very informative.
Thanks for taking the time..
Whats up ROY!?
@@Tofazfou
Hey Brotha!
Happy New Year..
Thank you.
Forget to add, the heat from your hand holding the mic will cause the mic to read larger than what it actually is. How much depends on the temperature of the mic when zeroing and the temperature of the mic when measuring along with what the cte of the metal is. IE, alu will move more than steel. That's why it's always best to use a mic stand.
I'm new to this i shoot slugs out my fx impact mk2 25 but ... I don't know what slugging a barrel is 🤔 hopefully I learn someday thanks for sharing tho I need do some more research on this
I measure bore and groove in my powder burner barrels, does the groove measurements have much effect in air rifles
good info
nice video ,sir
Thank YOU! Appreciate you stopping by
Hey Sir, that’s a great informative video. Hope all is well with you.
WHATS UP D???!!!!!!!
You got the same punch set I got, lol.
Thats too funny. They arent the best but, they definitely get the job done! THANKS
Great video. Thank you.
If i dont have a bullet. Can i use a pellet to get size of the slug i need to buy? Why are not swaggering your bullets?
Very interesting
thanks S.o. Glad you found it so. This gives me motivation to do more videos like this one.
Watched to the end, but still not clear on what this process actually does. Pushing a lead slug through the barrel changes the steel barrel diameter? That seems unlikely, I don't see how this process will do anything other than add rifling marks to the soft lead projectile being pushed through. What am I missing?
You're missing value of that specific information. The part you want to focus in on here is what YOU just said: ADD RIFLING MARKS TO THE SOFT LEAD PROJECTILE. So it can be measured. So you can obtain/swage/cast precisely sized ammo for your rig.
Bottom line up front; because you/we shoot a pneumatically propelled projectile, you need to achieve the best air seal within the barrel so that air doesn't bleed past the slug/bullet/pellet, AND do so without creating so much contact friction/resistance that the slug/bullet/pellet can't efficiently travel the length of your rifled barrel.
The point of Cedric's procedure is to properly determine the inner diameter of the barrel, so that you can utilize the best suitable slug/bullet/pellet size. Too small a diameter slug, you'll have a slower exit velocity (because of air bleed), impact power and shorter range. Too large a diameter slug and you'll have potentially erratic trajectory & flight characteristics because you effectively "choke" the slug for the near-full-travel through your barrel. You also risk fouling or jamming within the barrel, damaging your breach/breaching pin, or completely blowing seals within other parts of your gun or other-like catastrophic failures. Like your fingerprints, barrels will have nuance variations between them - no two are exactly alike. Mass production also plays, as manufacturers of the barrels/guns and the ammo leave a little "wiggle room" so that their product is more "universal" between shooters/guns/ammo (meaning they can sell more).
What Cedric demonstrates and explains is crucially relevant. Your barrel is rifled with either carved or smooth (varies among manufacturing/science/preference) internal twisting. Lands & grooves are the terms here. The "lands" are what contact that squeeze/grip the projectile; kind of "reaching into" the path of the slug/bullet/pellet thereby inducing the gyroscopic twisting that ultimately keeps the projectile stabilized once in free flight. The "grooves" represent the true inner diameter of your barrel and effectively the true size for the slug/bullet/pellet that you seek for the most efficient projectile. Observing the pushed-through slug like Cedric shows, gives you the true shape & measurement of the inner dimensions of your barrel from a full-length perspective; he used a slug to "cast" the inner shape of his barrel.
For more precise & efficient shooting, you'll want more precisely sized and efficiently shaped & weighted ammo. You can't rely on the generically (often mass) produced ammo caliber on the tin or box - especially the cheaper stuff. Barrel caliber size as stamped on the gun are also not guaranteed as PRECISELY measured. You will see the evenly measured baseline "foundational" caliber with respect to the produced barrel size, same with the slug when was swaged or cast. For example: .30 caliber versus .303 / .30-06 / .308 - which are all just ever-so-slightly higher variance diameters than the "foundational" size of a .30 caliber. This is what you typically find in the commercial market when you shop. You really can't tinker with reshaping the barrel to a specific ACTUAL caliber, so you're left with customizing the ammo that goes in it. Think of getting custom sized shoes for your feet; can't change your foot size, but the shoes...
By determining the "custom fit" of preferred ammo size for your gun, you can maximize the best consistency in your shooting results. After reading all of this, go back and rewatch the video - it hopefully makes more sense to you. Also, you can appreciate why specific producers like Nielsen Specialty Ammo or Corbin (swaging dies & machines) have seized on the precision sizing of slugs/pellets to cater to the shooters that care about what they feed their rigs, and I hope this explanation helps you. Best of luck!
@@JT-dy4sf Thanks for the awesome explanation. So in summary, he's simply measuring the barrel diameter by pushing a slug through. I think the jargon in the video threw me off! 😄 👍
Have you done this with a choked barrel and had good results?
When can we start placing order's for cast? I need some in .510 dia. 345 grain for my Piledriver .50 cal. I'm also order my .72 cal big bore Zeus. we need a website set to take orders.
I've followed ever post you have done, and your the reason, I big bore air gun hunt now.
Let's go..Awesome channel BTW
Where do you get the unsized bullets from?
Okay just saw your video on how to slug a barrel. I am trying to get into swaging my own slugs. Now how do I know if I tell them I need my slug mold for dye or whatever it's called, as you can tell I'm a beginner to this. That I needed at let's just say that .1722 size?
What do you do if you find tight spots when slugging a barrel Cedric 🤔
Well, if its SUPER TIGHT then more than likely your barrel is ruined. You see, a barrel is a tube of a nominal dimension for breech to muzzle. SAY .308 cal! Once you start the slug, it becomes basically .308 cal. When you hit a tight spot, the caliber then goes from .308 to something smaller. Lets say .307" cal. Then, after more pushing, it gets easier to push the slug again. Well, now, the outermost diameter of the slug is no longer .308" like the rest of the barrel but something smaller. So then, the barrel is no good. You can clean it and try polishing one with JB Bore Paste and then, reslug the barrel to see if the issue is resolved. If not, then i would contact the manufactures/distributor and have the oem barrel replaced
I am glad find this Channel,..
i have Question sir:
1 To Slugging Barrel just enough to push bullet with cleaning rod ?
2 if i have barrel 172 what the best size for Slug Bullet ?
3 if i have barrel 172 and the Slug is 177 what do I have to do?
4 what is the best difference between bullet and bore sizes
Thanks,..
I am Waithing for this Answer to😀
I think 1722 is Groove barrel diameter and 169 is Bore diameter.. Is it true ?
What is the purpose of doing this to your barrel?
Honestly I just wish you just explained what it was to begin with rather than assuming we automatically know. Seems like such a uncommon size to begin with but it's essentially pellet resizing. Be nice to know why people shoot this size for those that are new to the channel such as myself. Is it so uncommon people have to resort to forming slugs themselves because manufactures don't want make them or this just for people who make their own ammo from collecting deformed slugs and pellets?
Oh sir trust me, a video on explaining JUST WHAT IT IS, is coming up soon! It will be detailed and hopefully when your done watching it, you will have all your questions answered. Sometimes i work backwards. Its just how I operate. A lot of it has to do with "FREQUENTLY ASKED QUESTIONS".
Good info, Ced. You should send some lube to SG. Save some for your cankles. Lol
But seriously, great info. I'm glad you're my Sensei!
IMA GET YOU JOE😂🤣
@@Tofazfou 😆
Hi.. since the bullet was not sized it was not completely round...so we use the highest number of the measurement...?
put simply, YES!
Yes Sir! KnifeMaker
@@Tofazfou
👍👍
Thanks
What measurement will you use to size your resizing die bushing after measuring the slugged projectile ?
in this video? .1722". You size to at least BORE DIAMETER that you measure after slugging the bore
Is the process the same for a choked barrel?
VERY GOOD QUESTION. If you choose to do so, the answer is YES. Why? Because, chokes are not a consistent size from manufacturer to manufacturer (ie.....Lothar Walther vs BSA vs Kral). So, in order to find the best slug or even pellet size, you might want to size your choked barrel using a slug. This is a basic idea of how "CHOKED" barrels are choked, the breech of the barrel to about 3/4 of the way down the barrel might be something like .218", but, the choke of the barrel (last 2-3") might be .2165". This means, your barrel is choked .0015". So shooting slugs that measure .217" might be your best bet for accuracy. This gives you a very good starting point but, AGAIN, don't be surprised if .218s shoot better than .217's. There are so many variables of a barrel that you can't measure once you start a slug in the bore but, the premise gives you a good starting point in the right direction
@@Tofazfou thank you for getting back to me. I was always told that a choked barrel was bad with slug's and good with pellets. I have a AEA rifle and I have been shooting slugs very well with it. I was surprised to find out that it's a choked barrel, but they do theirs backwards from everyone else. They do 3/4 of the barrel the choked size. I'm going to definitely slug this barrel cause I'm curious what it is. I gotta figure out how to get this barrel off first then it's on. Thanks again buddy.
@@AlbeeSoaring You see, you just proved what i'm saying, EVERY barrel is different in its own weird way. And, to help with the confusion, back in the day, none of us really understood chokes and slugs and why chokes are there. But today, we have a much better understanding. We also have slugs no that have more O.D. than we did before. Like 22 cal slugs, we now have, .216, .218, .217" options which gives us a better chance of accuracy and finding the proper ammo for the barrel. We didn't have all this knowledge and technology 10 years ago
@@Tofazfou My brother! So, if one wanted to do the same using a choked barrel and diabolo pellets; after pushing the pellet down the bore, what area of the pellet gets measured with the micrometer...the head or the skirt. I'm guessing it's the head...seems most logical; but I don't want to be wrong.
What about my magnum 25 gauntlet ?
What about it? A barrel is a barrel. If its a gauntlet, the bore should be close to .250". So you would need some slugs that are .251+" to get a proper size.
@@Tofazfou thats what up t.f
so basically you need a resizer if your slugs are too tight
First, remove the barrel...POOF....MAGIC
