Thanks for the replies guys. Yes I have taken it to the range and fired the gun in order to compare it to my other 52's I own. It doesn't do too bad in the accuracy department, but the barrel certainly seems to "lead up" faster. I think what happens is the corrosion/erosion in the old barrel is right where the rifling starts more or less at the end of where a shell casing ends. I am sure there is some contact between bullet and barrel and lead just naturally transfers quickly to the rough part of the barrel.
I have called a number of high end pistolsmiths including C&S, but only they are willing to take on the job BUT it is a 12 to 14 month wait to get the work done. I could be dead by that time. I was surprised at how many pistolsmiths I spoke to will gladly work on a 1911, but want nothing to do with a Model 52. I called Smith and Wesson and talked to a rep there and asked about having their repair shop do the work. The rep was supposed to call me back but failed to do so. I guess I'll have to call them back.
So that's where I am in this quest. The barrel I purchased has never been installed on a gun and needs not only fitting, but finishing work as well. I naturally assumed that this type of work be no problem for a good pistolsmith, but perhaps I am wrong and there is some black magic to making a Model 52 work correctly.
