Well, I suspect it would give new meaning to "blue whistlers" anyway.

Minié ball in a smoothbore

Will, how can the tail of a mini be going faster than its nose? Or how can the nose slow down quicker than the tail? They are together!
Rifled slugs and others fly usefully from a smooth bore because the balance of weight forwardis just right. This allows the skirt to act as its flights. Attach a wad for the same effect as do brennek.
The minie might if casted with a bigger base hole and protected with a wad from the gas.
Or glue a wad/flight system to it.

Hello, Brit,
As it was explained to me, drag on the nose of the minnie causes it to slow a bit as compared to the tail. Causing lateral rotation. Yes, the projectile in its entirety is moving at the same velocity. (Kinda like a tire on the road? The section in contact with the road does not move while the top of the tire goes twice as fast as the car.) Once the projectile starts spinning, gyroscopic forces set up a push perpendicular to the axis of rotation.
I agree with 54. And, minnies are a bit longer than shotgun slugs. With saboted slugs for shotguns, the slug is wasp waisted like a slug for a pellet rifle. The "skirt" imparts drag to the base that stabilizes the trajectory.

And you have a trustworthy source OR any practical experience to back up that assertion?
As I asked another member, have you ever fired even ONE properly fitted minie ball, backed with a suitable load of BP, out of a SB?

I don't detect any spin but the slug does appear to be beginning to yaw.

True. They "looked like" they would make it spin.

I don't find them to be any more deadly on WT than the American-produced slugs.

AFTER its out the barrel a rifled slug will impart spin.
As described in patent US3200751, rifled slugs achieve ~ 10K RPM within 50 yards.

NOT according to the Winchester tests.

Tumbling is not spinning.
We need proof .....a patent description is not proof, it only describe the purpose it doesn't verify it.

By making a the whole slug longer, mass forward. You have made a very short arrow or dart.jproveaux said:
As soon as a tumble starts the wad acts as a Fletch.
Years ago I use to screw fibre wads to home cast slugs in .410". Out of my 410 back then no rabbit was safe to +80yds!

That's it in a nutshell. Sales gimmik.
No need or reason . A Minie type projectile is weight forward with a hollow base. There is some evidence that the base may indeed yaw a bit but it will NEVER tumble! I've shot them for years in smooth bore and never saw a singe incident of tumbling. Their accuracy is on a par with round balls from a smooth bored gun and is hunting capable out to 75 +/- yards. I even used the big .69 Mine from a Lyman mold in my Potsdam musket. which was about pie plate accuracy at 75 yards. OK but nothing to write home about. For board busting competition I'd shoot first on my team and have been known to load the Mine backwards. Accuracy was good enough to bust the stake and it would knock a big ole chunk out of a stake! Team only had to put one or two next to the gap I'd made! They've fun to shoot but do up the recoil level and use up a lolt of lead in a short time. have given up on conicals since ball has taken eveything up to and including bull buffalo and repeated test showed balls 16% more effective than any conical made in 2006.jproveaux said:

I can't find the Winchester test anywhere. I would like to read them.
The patent (which would require proof of claims to be issued) states that it spins 10k rpm at 50 yards. Compare that with a rifle/bullet (40k rpm at 50 yards and while significantly slower, it does spin

I do not think there is any question that the exterior grooves were added to try to impart a spin and to allow a crush surface on the slug as it passed through the choke.
I recall that fairly early in the field testing, the spin part of the slug was pretty much dismissed in all the gun and hunting magazines.
Besides the crushing of the "rifling" grooves as it passed through the choke; the air itself does not have the ability to impart any significant spin on the slug in its short time of flight, even if the grooves were full sized. A bullet spins many thousand rpm.
Also that said, the proof is in the results and the shotgun slug has killed many many deer and other game. Slugs work, even if not as intended.
The only way to know if a civil war mini will work in your smoothie is to shoot it. Given the variables of barrel bores and slug diameters, the result are sure to vary.

I suspect they would tumble upon impact/entry and be very devastating to a live target......Did you ever kill anything with them?
Pops buffalo .58 conical of 500gr+ was recovered and was about smashed flat on the far shoulder under skin....but nothing glued to it. I'm betting as it was still pretty much a conical it did not tumble at impact :idunno:
