.69 Cal. Minié ball and .73 Cal FURY slug - 12ga. Rifled choke tests
Ғылым және технология
In this video we see if a rifled choke tube provides enough spin to stabilize two unique slugs. Many people just don't have access to a full-rifled barrel, so if these function well, it gives them another option. These are just initial tests and we'll dive into both of these deeper in future videos.

True, but in a pistol the projectile engages the rifling nearly at the moment of acceleration, whereas these slugs have reached peak velocity before meeting the rifling, there also seems to be a slight ledge the projectile must squeeze through at the start of the choke. I wonder if it would make a difference to taper that area into a ramp? I don’t think there’s any immediate problems, but there is a general feeling that the sudden change would effect ballistics and trajectory in a less than predictable manner. I’m imagining a speeding vehicle suddenly grinding against a barrier, any slight imperfection in the choke could mean quite a variance in efficiency, travel, and/or energy. Just thinking out loud I guess.

Obviously a true rifled barrel is gonna be better but I’m guessing the biggest difference will be velocity loss converted into heat and blow-by from the sudden impact and deformation. If I was a betting man I’d say the difference would be much more significant at range such as plus 75yrds. I can hardly wait to see what the boys have in store for their testing.
In Russia most rifled chokes are 1:900 mm twist rate which is almost 1:36". When it comes to rifled choke you have to pay great attention to it's muzzle. Because it is in fact equivalent of rifle's crown. These slots for choke wrench is a DISASTER!!! If you have access to a lathe you should cut this choke until slots go off, make decent muzzle chamfer. To screw this choke in and out - make knurling in the middle and use bicycle-chain-style (or oil filter style) wrench.

Yes. Also I wanted to add that was its greatest strength because it was designed to be undersized compared to the bore to allow faster loading and more accuracy with the muzzle loading rifles of the time. At the same time that expansion also worked against it since it is a solid lead slug, sustained fire would quickly cause fouling to build up in the barrel.

I doubt it would expand that much. It was sloppy in the bore of the tube. Definitely more so than the bore of a rifle.

A minie needs to be very close to bore size when muzzle loaded. In competition we keep them to within 1 to 3 thousandths of bore size. The minies I sent to Jeff are about .687 and a shotgun bore is about .730 so, it just cannot expand that far. Jeff’s use of a shot cup filled the bill nicely.

I have a mold for 58 cal Minie bullets . I think I'll give them a try in my 12 ga . I also own a Thompson Center Pro Hunter rifle with two barrels , one in 7mm Remington Magnum and the other in 416 Rigby . There is a barrel for the TC Pro Hunter chambered for 12 ga fully rifled that I've considered buying . There's another 12 ga barrel choked for turkey hunting that I've also considered . I haven't fired my TC yet , but I've loaded some test rounds in 7mm Remington Magnum and am about to load up some 416 Rigby rounds . Thanks TFM and crew . You guys are making some great videos .
Holy mother of god....that Minie ball destroyed everything...nice, I look forward to the next vid.
That last shot looked like a bomb went off!
How to break OGs shoulder in 3 easy shots... Greg’s a beast!
After shooting those +40 grams bullets, O.G heavy metal band "Sturdy Lefties" would skyrocket the music charts.
Glad to see the Minei ball spin. The skirt is supposed to expand against the rifling under pressure for good engagement. As it was designed in the muzzle loading days, it was desirable to have a projectile you could actually push down your barrel that had tolerances that were somewhat looser than 0.001".
I was just looking for something to watch lol great timing

Only 5" of rifling? If I am remember correctly there are a lots of snub-nose revolvers with barrels much shorter than 5"... And they are accurate. It is hard to shoot accurate from snub nose, but that is because small sight radius.

The real difference is that the bullet is accelerating in the rifling the entire time in a normal barrel. In the choke it is already moving at full velocity and has tons of inertia before it hits the rifling.

@@matthewchastain136 You are absolutely right. But in what this difference transfers in terms of slug ballistics? I mean what effect this have onto group size, accuracy etc.? In Russia fully rifled 12ga barrels are scarce because of the law. To be able to purchase any rifled weapon a person must previously own a smoothbore during 5 years without problems with law. Here are no significant hunting restrictions to use rifled weapon. Therefore russian gun makers just do not make fully rifled 12 ga barrels. We basically limited to rifled chokes, again because of the law. If long barrel has only 140 mm of rifling or less it is considered smoothbore. Rifled choke in non-restricted item. That's why it is very popular in Russia.

You're a rather successful channel, and could be the gold standard in Slug testing....IF you'd *TEST* THEM out, rather than merely try them out. It occurs to me that most any of them will hit minute of man @ 15 or 25 yards... but let's see which ones are the best.
That brick exploding is possibly the best slomo shot I've seen on the channel! P.S. Im happy to see ads, and I dont skip, just for you guys.

IIRC, Minie balls were designed to be used in rifled muzzle-loaded arms. The arse end of the projectile should be hollow, and the intense pressure of the powder and whatnot inside that cavity forces the grooved portion of the projectile to expand outwards. That allows you to put the undersized projectile down the barrel easily enough for muzzleloading, but also allows the projectile to engage the rifling when fired. TL;DR y'all should try the Minie balls again without the shot cup or a gas seal or anything and see if it works right :D
My shoulder just separated watching this.
Yay for mini ball!
Wow! This is really interesting. I have never thought of sending an old powder mine ball out of a shotgun.
Jeff, love the cammo Bear Bryant hat.
Beastly
Good stuff!👍👍
What you have there is a “Paradox”, a type of slug-firing shotgun invented in 19th century in England. Now you can buy air rifles with this type of barrel that are super accurate. The Germans in WWII used this method on anti-tank guns with good results.
holy smokes that mini was awesome

Another fine video chaps, I must ask though have you observed any clear differences that rate of twist makes on these large but relatively slow projectiles? I hope Danny's recovering well (and the OG too for the contusions some of these projectiles are dishing out to his shoulder).
You guys need to shoot bricks under ballistic gelatin more often, that was cool!
