Are you useing reloads? Have you tried .44 spl? I read somewhere that they tried to make these guns for both the Mag and the Spl and the guns will tend to favor one over the other.
Could there be a burr or sharp edge on the bottom of the chamber that could use polishing?
The other thing I would suggest in figureing it out for yourself is to break it down and !st compare the New parts to the old, 2nd compare to someone's .44 that does work. If every thing is the same, there could be a receiver flaw where the the carrier henges. I watched mine(81') and the angle is very low and it rises almost even with the bore.
