Well I just can't stand it any more... Lowell, as you once told me you are the prince of the etherial or something like that.
This is much, much simpler than all that complex stuff you normally delve into which I could never do with the style you have. This is just about simple metal. The stuff stretches like clay to a high degree, especially damascus, but also that old steel your Beeze tubes are made from. I can't tell from the discussion how bad the damage is but suspect its relatively low in the scheme of technically defined "elongation" limits.
As for being able to "feel" the difference between a Teague lined gun and one that wasn't, it all depends on whether or not the total amount of steel is increased or lessened during the lining process. I can tell you with certainty that the specific gravity (weight per specified volume) is so close no matter the alloy of steel or even the 17-4 PH (precipitation hardening stainless steel that Teague uses in his chokes and maybe his liners), that no difference in "feel" could be possible if the same amount of metal was in the lined barrels.
There should be no reason to add metal during the Teague lining UNLESS the original wall thickness was unsafe due to honing out over the years or re-striking of the outside. Teague will bore/hone the inside bore until the walls are extremely thin, then insert a liner of adequate wallthickness to restore proper bore diameter. I'm guessing his liners are in the area of .015 to .020 wallthickness themselves, maybe even custom matched wallthickness and diameters for the job at hand.
But, frankly, I'm not convinced the bulge has caused weakening of the barrel. Someone like Teague will be able to assess it better than I or most of us here.
