Not the same exact internals.
617 vs 586 vs 686: the 586 responded better to a self action job than did the 686,
different steels responded differently. The regular steel vs the stainless steel is different. I rate my 586 steel with an action job better than the exact same action job on my stainless 686. And I rate both the 586 and 686 better than the same action job done on the 617.

Whether its over all gun weights, cylinder weights, hand weights or whatever...there is a difference. Nothing is the same on different models and especially different calibers!

These results were based on actions slicked up by my own hands, maybe...just maybe I was better one day vs. the other?...perhaps... but the 586 feels the better overall than all the others

*the hand as well as cylinder are different, and to add to that...the hand is even different from a 6 shot vs a 10 shot 617...Too many differences to say "its all the same".
