JPK:

I figured re-chambering would be $400 to $600 and re-regulation $600. I did not include re-blacking the barrels because it usually isn't required. It wasn't the last time J.J. re-regulated one for me.

Nothing wrong with .450 3.25". Sure beats .458. I've seen a number of .458s re-chambered to .450 No. 2 and others to .450 3.25". Just depends on how much steel you have to work with.
