I was trying some Hi-Tek coated bullets last week in my M-29. I had loaded them for my Ruger Bisley .44 Special but gave them a try in my S&W. They shot better in the M-29 and left no leading at all (with EDM rifling!) And indeed, they shot slightly better in .44 Magnum cases. So little recoil in the heavier gun that I could shoot them with one hand! They smoke so little I'm going to try them with Titegroup!
Thirteen shots offhand at 25 yards (blew one) with the Model-29.
