Strength of ML barrels

[roundball]

Is a "Sharon" barrel made out of any different, or better/stronger steel than a GM barrel, a TC barrel, etc?

 

[Slowpoke]

Colerain, GM, Getz (Sharon), Rice are made from 12L14 Bar stock, Ed Rayl makes his from 4140 bar.
Now this is a little cloudy because 100% sure but I believe TC and Pedersoli barrels are poured lead barrels and not out of bar stock. All of them strong enough but you talk about a can of worms..... just ask someone that "knows what they're talking about" which is better between them. All of them safe.

T.C inline barrels I guessing they're out of bar stock.

The Green Mountain muzzleloading barrels that Track has are from 1137 steel and the BP cartridge barrels are 4140. I had just read this and was placing an order so I asked them.

My charts show the 1137 to be quite a bit higher tensile strength than the 12L14.

They are much stronger than most folks think..................An old test was done, and they kept adding powder, had it plumb full and couldn't blow it up..........then they put some smokeless in it, and see blew....a Morse rifle if I remember correctly........ :hmm:

I seriously doubt that you can blow up a well breeched muzzleloader barrel with one projectile in the barrel. I shot 200g of 2F out of my shootbore 20g....2 twice, both at 100 yard paper targets... someone came up and talk to me and I forgot I'd put powder in, so I dump another measure full. Since my gun weighs a little over 6 pounds it about detached a retina and separated my shoulder....

I'm not sure what "poured lead" is but I am sure the TC and Pedersoli barrels are made out of steel.
I also don't know why anyone would cast a barrel with a uniform crossection which leads me to belive both companys use bar stock of some sort.

I don't have any data on 1137 steel however 1132 has a tensile strength of 83,000 (HR) and 92,000 (CR) psi with a yield strength of 45,500 (HR) and 77,000 (CR) psi.
12L14 tensile strength is 57,000 (HR) and 78,000 (CR) psi with a yield strength of 34,000 (HR) and 60,000 (CR) psi.

HR = Hot Rolled
CR = Cold Rolled

Thanks Zonie you said what Ive been reading in these old MB, all the powder and 2,3,4,5, balls your going to blow the patch way before the barrel. at least thats what major barrel makers told me, and they bulge not blow when you go to far. Fred :hatsoff:

Here's all the dope on 1137

If you know the steel number, Efunda has the properties.

12L14 contains a low concentration of lead and is referred to as lead steel.

1137 an all that MIGHT be 'Good nuff' but he WONT have it in tha shop.

MINIMUM Chrome-Moly he uses is 'ETD-150' yields at 130.000 tensile 150.000 an rockwells at 32C.

MOST a what he uses gets up there around 200.000 ta 275.000 psi. Why? He dont skimp on tha best materials or workmanship!

Not tryin ta make this an advert, jus pointin out ifin things get kinda stacked wrong agin ya, 'good nuff' real sudden AINT so good.

He spent a whole buncha money simulatin different ways a man could screw up an do in a barrel, anythin that took out a 1137 er leaded steel barrel wasnt comin close ta doin a good chrome-moly or 410/416R or 440C lined chrome-moly with a patent breech, somethin about 'hoop strength' and engineerin talk he does.

1137 and leaded steel gots somethin fer it. its CHEAP an its easy an fast ta machine, its easy on toolin.

But it AINT, my opinion, what ya want fer a barrel.

MOST a what he uses gets up there around 200.000 ta 275.000 psi. Why? He dont skimp on tha best materials or workmanship! and he uses this for muzzle loaders, not the kind we dont talk about here but real old time type? My 45/120 Sharps with a 120 grs 2f, 500gr bullet was about 30,000 psi cup, and 53 grs of imr-3031 at 32,33,000, hows that figure to your kind of figures (what kind of psi?) Fred :hatsoff: I can be wrong but thought cup was higher than psi.

I'm not sure what "poured lead" is but I am sure the TC and Pedersoli barrels are made out of steel.

Poured lead? I don't know what that is either, had a brain malfunction because I meant poured steel. I know that traditions and Pedesoli use cast steel barrels and I would guess that TC does too.

I don't know enough to talk on the subject quality of steel.

Jus sos ya know i gots interest, i works for Tha MANN at BIGIRON Rifled Barrels.

That may be fine for smokless barrels, but I'll stick to leaded steels for muzzleloaders, the softer the better. :thumbsup: In fact, I'd be comfortable with wrought iron if I could get it.
Old damascuss barrels are fine by me too, I've been shooting a set of damascus barrels that are fast approaching 200 years old....no problemo....

 

[manyirons]

Sample of one i'd say an i know ya can go fer years an 'no problemo' until there is.

Safety margins AINT a bad thing. An my experience, soft WEARS.

So's we's both happy, i'll keep mine hard tough&strong, you have yours soft&weak.

An yup, i have a damascus i shoot on occasion, dont say its a great idea, but tha guns so nice, tough ta resist!

No, I don't believe it is.

 

[Va.Manuf.06]

:hmm: Weak and strong are relative. What you are doing with the barrel makes all the difference in the world. I'm with Mike. (.58 caliber revolver?)

 

[manyirons]

Yup, .58! And that cylinders made a Airmet 100, Maraging Steel or Carpenter 465. Alla them REAL strong. Some loon drops a loada smo....less in er, its hangin together.

 

[talon]

As far as the poured part, back in the 80's there was an outfit that made muzzleloaders in Spain.Their guns were cheap.They cast their barrels with steel like you would cast iron. One of the barrels blew up. The owner of the barrel had it x-ray tested to try to determine what it was made from. X-ray showed flaws in the steel from being poured. The company went out of business quickly to avoid liability. I guess you get what you pay for.

Bountyhunter and Zonie, thanks for the technical data... :hatsoff:

:shocked2: I'm sorry, I wouldn't count on it.
