tubing barrels

[CoyoteJoe]

I just ordered a 28ga smoothbore barrel from Jack Garner. He had just what I wanted in stock. But thinking back on our conversation, he did mention that his barrels were made of heavy wall steel tubing. That doesn't sound like the best way to make a barrel. Anyone know about the practice?

Joe,

It may sound a tad scary, but most of the smooth bores that people are shooting use this same material for the barrels. This is not a recommendation -- just a comment.

It is no secret that Jackie Brown and Jack Garner both have done this for many years and seem to have confidence in their barrels.

I works well for me, but I am pretty careful how I feed it.

If there is a concern out there, I would like to know about it as I shoot a 20 gauge Tulle with one of these barrels.

YMHS,

Here is what I posted to the topic of used shotgun barrels

Copied message;

FWIW, might try 4130 chromoly aircraft tubing. I've helped make three or four barrels from this material 1" od X .156 wall. <a bit more like a 15 gauge at .688 ID >

For a test run we breeched a 1' section and loaded it with 200 grns powder and a 2.5 oz slug. ( that we aslo made a mould for) The tube was mic'd at four positions, around the circumference and down the length. fired three times with this load, there were no changes to any of the measurements!

and this is a lot more, than the 85/90 - powder/shot load I'd shoot at a turkey.

and there was a CVA aftermarket barrel 1" acf X 12 gauge, for the St. Louis Hawkens.. Now that's a thin barrel!!!

Early Rustic arms use's some type of seamless tubing said he proofed it with several loads and ball without a change in the dim of the tube must be pretty good

Some hydraulic tubing can withstand terrific pressures. Hydraulic impulses in certain high pressure systems have been known to hit over 100,000 psi.

I've used a number of guns over the years that had barrels made from seamless drawn tube and never any trouble. I have even used rifles with drawn welded tube barrels, and no doubt so have many of you !! The British .577cal Enfield ML rifle barrels were usually drawn from a longitudinally welded length of short heavy tube. I have only ever seen one of these blow and that was with a load of 2 1/2 drams, by volume from a powder flask, of a particularly hot smokeless powder called 'Cadet Neonite'(I never worked out the weight in grains). The gun split at the breech exposing the length of the breech plug. There was no other damage to the rifle and none to the shooter.

I recieved the Jack Garner 28ga. barrel yesterday, which was very prompt service. It is 15/16" straight octy for 12" then a wedding band and tapered round to the muzzle. It came with a well fitted breech plug, 5/8x18, which I had to pull and replace with one made from a bolt to match the hook breech tang of the T/C rifle I'm rebarreling. No doubt it is tubing as there is a highly visible seam up the bore from end to end. :hmm:

Most people use a 1084 DOM tubing. It has simular tensile strenght to 1137, or 12L14. It is easier & cheaper to get than 4140.

"No doubt it is tubing as there is a highly visible seam up the bore from end to end. "

Could be they forgot to rotate the reamer when they extracted it. I have seen this happen when just dragging a very hard and sharp tool out of a bored cylinder.

As Judge Roy Bean supposedly said "might rain whores too, but I doubt it". Just joshin ya, that wuz a good thought, but I aint talkin no little scratch, it is clearly a welded seam. :haha: :haha: :haha:
