Unlike most posters here, I'm not very knowledgeable about revolvers since I own only two. One is a Model 686-1 with 6 inch barrel and the other is a Model 66-2 with 4 inch barrel. The Model 66 is reasonably accurate (when fired from a pistol rest) but the Model 686 has been erratic since the day I purchased it new. The clearance between the forcing cone and cylinder face as the cylinder rotates is as follows for the Model66:
1 = .007 inch
2 = .006 "
3 = .006 " "
4 = .007 "
5 = .008 "
6 = .007 "
For the Model 686:
1= .006 inch
2 = .007 "
3 = .0075 "
4 = .006 "
5 = .0055 "
6 = .0055 "
When I had the "gunsmith" at the dealer where I bought the 686 check the variation in the gaps, he noted that the they were within "factory specs" and timing was perfect and the revolver was returned by the sales clerk with a bill for $20. I never had an opportunity to discuss with the gunsmith why it was so inaccurate when compared to the shorter barrel Model 66. Does anyone have any information concerning whether the variations in clearances noted above are normal or why one model is so much less accurate than the other?
