I am lucky enough to own four 44 Mag revolvers. I measured the throats this morning, as I noticed some leading in one of them the other day. The average cylinder throat measurement by revolver are:
S&W 629 - 0.4295"
Freedom Arms Model 83 - 0.430"
Ruger Redhawk - 0.4315"
Ruger Blackhawk - 0.433"
The bullets I am shooting are Leadheads (RIP) 255gr plainbase Keith SWC that are sized at 0.430". The Redhawk was leading up more than I would have expected, but I hadn't done any measuring prior to shooting.
I would like to shoot one bullet in all four but am thinking that I may have to use the 0.430" bullets in the Smith and the FA, and buy "gasp" jacketed bullets for the two Rugers. All of these were bought used and so I have no idea who may have done what to any of the throats.
Any thoughts or suggestions?
