I just received a phone call from Dewey Vicknair, concerning my doubling issue. There was no congealed lubricant in the action. The problem was a part made from a casting that was not fitted correctly. After stoning the working surface of the part, he fired a box of shells and attempted to make the gun double. I was relieved to hear that there actually was an issue. There is nothing worse than being told that no problem was found.
