.69 Cal. Minié ball and .73 Cal FURY slug - 12ga. Rifled choke tests

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.

After all, 5 inches of rifling is more than a lot of pocket pistols. Thanks for sharing these awesome videos.

[@taofledermaus]

thanks!

[@jacobacon3219]

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.

[@TheOlsonOutfit]

@@jacobacon3219 I'm sure it makes some difference, but probably not within the margin of error already present in shotguns.

[@jacobacon3219]

leif52pickup Yeah that’s a good point.

[@john-paulsilke893]

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.

[@LexsLavrov]

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.

[@andymcgowan9819]

Will not the mini ball base expand to engage the rifling once it’s fired wasn’t that the original design?

[@GunFunZS]

Not with a gas seal behind it...

[@Greymist73]

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.

[@Highstranger951]

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.

[@patrickmihajlovic4112]

Designed for EXPANDING !!!

[@larctiger]

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.

[@marklarson8121]

Great job guys! I love explosive results! All ways top notch and very interesting! Have a good one guys see ya next time:D

[@Darthdoodoo]

Good sciencing brozos😂😂 we love a good slugeratin sciencification presentation 🎉

[@Fudmottin]

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".

[@peabow1031]

Thanks guys very interesting!

[@LexsLavrov]

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.

[@JefeInquisidorGOW]

I mean, most self-loading handguns have 4" barrels and are good for 100m or so

[@matthewchastain136]

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.

[@LexsLavrov]

@@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.

That mini ball looked like a lb. of c-4 going off! Way cool!

[@wtechboy18]

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
