Throat erosion or not so eroded?

Forget pressure, bearing surface, heat, powder choice, cartridge, and how well you try too keep a rifle in best condition. Lets just say lands and grooves look good and rebarreling is not what you are going to do. Your throat looks like southern Arizona pavement with road kill and buzzards circling waiting too consume your presious barrel. If you could change out from the chamber to a few inches of rifling would you do it? If the design, function and all deamed safe. Would you?

You’re talking about sacrificing a few inches of barrel/rifling, correct ?

No, it gets replaced as 1 unit with the chamber. Or yes a few inches gets cut off, but gets added back on when a new chamber is replaced. I know the rifling will needed too get in sync with the remaining barrel.
