Revolver Accuracy

What is shooting the best? Colt?  L frame S&W? K Frame S&W? N frame S&W? Blue? Stainless?  I'd think that the PPC guys would have worked out all the best modifications years ago.  Now I'm not talking how well you can shoot one.  I'm asking about accuracy with the best Distinguished Revolver Ammo from a machine rest.   Guess the Colt would have a from the hand sight advantage with the fine Ellison sight that is available on the Python.

I doubt new 38 revolvers and ammo of any brand will match the good old days Colt OMM and Remington Tgt ammo.

Im using a 6" Manurhin MR73 in distinguish with the non triggerstop trigger. For factory It works best with American eagel 158gr.
1,5" on 50y.

For handloads it's either Hornady XTP with longshoot or Nordic bullets with N320. 1,25" on 50y
