You say they "are NOT salvageable",can you load rounds into the chambers with moon clips? I bought a 625 years ago that someone had done what you are talking about,the only real problem I had was that i could not fire 45 AR in the revolver due to the depth of the chamfer but the revolver would shoot 45 ACP with moon clips.Just so I could shoot 45AR in mine I sent the revolver back to Smith and they fitted a new cylinder.I forget the cost and this was 3 years back.
