Have 2nd model S&W HE in .44 special, this gun is extremely valuable to me as its accuracy is about the best I've own. It is also a conversion that was once a .455 brit WW-1 gun.
I was able to procure a 5 inch S&W barrel and cylinder, both were in .44 spl. The Texas gunsmith did a fantastic job of polishing and refinishing the firearm, but the headspace was not good and most of my reloads would not rotate in the heas-space he provided. There was also a lot of end-shake.
As it cost $45 one way to ship by UPS I elected not to send it back to him. Instead hunted for local Wisconsin gunsmith. It was a crap-shoot and I sevened out with the one I found. He opened up the head-space but this moved the cylinder forward enough so the cartridges could rotate. But he also removed too much from the barrel breach causing excessive cylinder gap.
Now I've got powder residue and lead splatter that is really bad bouncing off the underside of the frame's top-strap and the little indentation scoop S&W put there.
This splatter builds up a horrindous amount of lead crap that deposits itself on the high forward points between the cylinder flutes. It is difficult to clean off and in time will take the bluing off doing it.
So, need an expert S&W pistolsmith who can resolve this problem once and for all. Can anyone recommend one in northern Wisconsin or nearby state.
================================================== ========
Can the extractor button that closes into the head-space breach area be made to push the cylinder even further forward thus reducing the barrel / cylinder gap?
================================================== ========
Or should the barrel be removed and have the shoulder lathe turned to set the barrel further back toward the cylinder thus tightening up the cylinder gap?

Here is a pix of my fine old gun, its a fantastic accurate firearm. It's the top revolver in the picture, the bottom gun is same model in .45 Colt.
