Interesting

I guided a brown bear hunting client who wanted to use his bow but also hauled along an ultralight rifle with a titanium barrel just in case. He told me the claimed barrel life was listed at 200 rounds !! So he didn't shoot it often .
But he got a bear.

We have on the rack a 30 caliber titanium blank. Tapered but not threaded or chambered.
Was made but the people who had the barrel making equipment before us.

Would the titanium barrel be better with steel rifling and bore insert? basically a titanium barrel with a rifled barrel sleeve?

Our Rem XCR II in 375 Weatherby weighs 7 1/2 lbs with scope unloaded. Seems light enough.

Would be easier to make then rifling a TI barrel

I talked with a guy who said maybe, possibly he could EDM the rifling.
It may take a few try’s.

Seems to me that if you want light weight, a carbon fiber wrapped stainless steel barrel would be the way to go.

I thought titanium was harder and stronger than steel, so why would it wear out faster (just asking)?

I watched their videos on that titanium shotgun. Looks neat, but I’d want to actually hold and point one (ideally shoot one) before putting up the bucks something like that would cost.

I’d have real questions about rifling titanium. I never knew anyone had actualonly made a titanium barreled rifle.

I have seen titanium actions on all kinds of guns, and have a revolver with it, but no barrel or cylinders. I was told it was too hard and would crack was why regarding the cylinders on revolvers, but this shotgun seems to disprove that, and now Phil says he had a guy with a titanium barreled gun, so I guess that’s wrong.

That is quite interesting. I guess he would feed the barrel and rotate at the same time?

This works for shotgun barrels. What about pistols? Titanium wheel gun?

Bowen has done a .50AE Blackhawk with the cylinder, base pin, barrel, and other small parts all made from Ti.

My only experience with titanium is with bicycle frames. Light and strong but they cracked on a regular basis and were unrepairable. I never had one as the perils of others was enough to turn me off them. Wonder how a rifle barrel would hold up.

I believe a Ti alloy barrel would erode very fast. My recollection is that it does not like hot gasses at high temperatures and high pressures. I remember asking one of our design guys ( we made rocket motors) why they didn't use it and he said they did once and it was a spectacular fail.

Yes, but it throws white sparks every time you shoot! Ti barrels have been tried before, but to have any sort of life it would need to be lined; and then you'd be better off with a carbon fiber barrel.

Yes I have TI Taurus 41 mag with a stainless barrel liner.

So yes they have already done revolvers.
