I tried three factory loads as well as my reloads at the local range. All reloads were mic'd to insure proper length of both case before loading and total length after loading. The gun was binding during all live round testing.

In a separate test I resized 6 cases in a Dillon 550 and 6 more on a RCBS Rockchucker. The problem persists.

In both tests all cases were inspected to make sure they were properly seated and an inspection of the extractor shows nothing (at least to me) to be out of alignment.

The cylinder cycles freely when it is closed with no cases in the chambers.

I will turn over to a smith to check for "misaligned or improperly fit extractor rod, misaligned yoke barrel, out of spec front or rear gauge (or both)."

Perhaps the previous owner tried the cylinder one hand wrist snap close from his favorite TV show.

THANKS for all the advice.
