Hi Rick,
Good question which is often debated by knowledgeable people and also by those who believe everything that their great uncle told them. Oh, then that are those who read in in a magazine or a website so it must be true... Good grief for most of those experts don't know the difference between yield and tensile strength, let alone what neuberization is.
The above rant stated, I have vintage guns with Damascus barrels which have the minimum barrel wall thickness throughout the entire length of the barrels appropriate for SAAMI maximum mean working pressure loads, i.e. modern factory loads. I also own guns with fluid steel barrels which are thin enough at high pressure areas that even a risk tolerant shooter as I will not shoot over 8000 PSI loads in them. In factory ammo RST loads are around 8000 psi.
If the above is Greek to you then please read, learn to measure your own barrels, do the math and only then make an informed decision that you can live with.
PS: If shooting old guns scares anyone please know that jet aircraft engines would tear themselves apart if it were not for neuberization of the stress. The stess in these engines, like the ones on passenger jets, exceed the ultimate tensile strength of the rotating parts.
