You don't always need to waste an otherwise good S&W barrel just because it has a damaged forcing cone.
I have a 696 which came to me having a barrel with an oversized forcing cone. A couple years ago, after I had S&W replace that barrel with a "no longer available" new barrel from a special "discarded parts bin" (gotta talk to the right guy, and I paid 'em for it too), I then had the old barrel just laying around.
This year, I cut the forcing cone off of the old 696 barrel and fitted what remained of that barrel to a Charter Arms stainless .44 Special Bull Dog to replace the crummy factory barrel. The 3" barrel shrunk to 2-3/8" and I now have a C.A. 44 Bull Dog with a "match grade" barrel, though I'm not exactly sure now why I needed it.
