The main thing to remember is that Barrel quality is un known until you shoot it.
With that being said the answer is yes i have had mixed results, but some turn out well considering.
The procedure I prefer is to first bore scope the barrel after a bright metal cleaning.
If the barrel looks good then I set up in the lathe and cut the new chamber or set the original chamber back 1 thread,inspecting the chamber as I go. (You can see the uneven cut of the original chamber as it cleans up.
If it cleans up you have a chance to salvage the barrel at this point and have not wasted any time and labor on an otherwise worthless barrel. This is the way to get started if you are a future Gunsmith using an old rifle that would shoot just ok.
At this point I commit to trying the barrel and spend the effort to Blue print the action. set the shoulder back, set the breach face and head space the chamber.
Don't expect a 1/2 MOA rifle, but sometimes they will improve quite a bit and if you have a good bore, they will surprise you.
I personally don't recommend this if you cant do the work your self because the cost of doing the same work with a new quality barrel is the same generally except for the new barrel cost, and the outcome will almost always be much better.
