I am looking for a gunsmith to re-contour a SS custom barrel from magnum contour to Remington sporter. I want to send it to someone who has done this before and undertstands the process so that accuracy is not jeopardized.

Re-contouring will actually change the bore and groove diameters, therefore there's no way one can predict it will maintain it's original accuracy level.

sell that barrel (or keep it) and get a new one.

Agree with the above: check what Shilen and other barrel makers think about "re-contouring", after the barrel has been lapped. Any expectations/guarantees about future accuracy are a crap shoot, at best.

General concensus is not to re-contour a button or hammer forged barrel for the above reasons. A cut rifled barrel should not have stress issues and is fine to re-contour. Alot depends on what your accuracy, or lack there of, requirements are.
Now, you'll get alot of opinions and answers from both sides of the fence. I had a heavy varmint tapered barrel I wanted to do the same thing to, so I called the maker, Gary Schneider, and he recommended to not do it, but would if I insisted. Results after that were my problem. I decided to not take the chance, so I put the money into a new tube.
I would call the maker and decide from there.

As said above. Get another barrel. Anytime you machine the outside of a barrel or tube you will change the inside tolerances.

I believe R. W. Hart will do it, but the above responses are correct. You can contact Hart at:

I wanted to re-contour a heavy target barrel that I brought from Broughton Barrels. I called Tim North (owner) of Broughton Barrels. He said that he could do it but the cost of doing it would exceed the cost of a new barrel as he would have to do all the stress relieving process same as a new barrel. I sold the barrel and bought a new one.
