Measure the overall length of your cartridges then fire three rounds and remove the clipped rounds and measure the length of the remaining three rounds to see if your bullets are unseating due to recoil.
Model 25-2 Jams With Moon Clips

DwayneV,
I can't see anything wrong with your position so far, but if it is correct, I'm wondering why we don't have a lot of people with the same problem.
Is there any chance that your gun has excessive headspace which is not an issue with single cartridges but is when the clipful of cartridges is holding the fired one in place?
I guess you could mike a case or two (.898"), and then measure between the chambered case and the recoil shield. Not sure what the space is supposed to be, but probably somebody here knows.

I think I have identified the problem. I unloaded a fired clip assembly that was not rotating freely and chambered the fired cases without the clip. These cases with the bulged primers rotated freely. I then loaded the same cases in a Ranch Products clip. The loaded Ranch Products clip rotates freely.
It has to be this batch of 100-piece moon clips I got such a good deal on from eBay.
Saturday, I will load and shoot with some Ranch Products clips to confirm everything and report the results here. I think all will be good.
I never expected this. Moon clips are moon clips, right? Wrong! Thanks for all of your support and suggestions. Does anybody need some extra-thick 45 ACP moon Clips? I’ll make you a good deal.

DwayneV, you can always sit down with those out-sized moon clips and an Arkansas stone while watching TV and thin them down by rubbing them on it. 
Throw a little oil on the stone and rub away while watching the tube and check them periodically against the good ones you have. Heck you don't have anything to lose by trying.

Moon clips come in several thicknesses, from 0.038" to 0.048". The most common are 0.038" and 0.041"
You should determine which thickness is compatible with the headspace of your revolver.
If you are using military brass (or range brass), the pockets may be loose because someone reamed them incorrectly. I use a Dillon Super Swager. If the pockets are tight, the swagger will resize them without removing metal. If okay or too loose, the swagger will not make them worse, and you can feel the tightness in the lever. A reamer will always remove metal, even if not needed.
Oversized fire holes will cause primers to back out. Again, this might be caused by improper case preparation. I bought a bunch of .45 Colt cases one time, marked for use as blanks. The fire hole was nearly twice the diameter of the correct brass.

Did not know moon clips could be such a science (or are they an "art"?). 
I bought a pack of 100 from Ranch Products when first produced in the early 80s and have not looked back.

Good news. Everything works fine as long as the moon clips are no thicker than 0.036 to 0.038”. The Ranch Products clips work great. I will be getting some more of those. The thicker clips are unusable in this revolver.
