I have a 629 Classic that has a measured .002 end shake .
Should I just leave it alone ? Just to see what would happen I put in a .002 shim and the cylinder would hardly turn .
I shoot this gun a lot but with a reduced load of a 240 grain bullet at 970 fps .
Thanks in advance .
According to Kuhnhausen, endshake does not require correction until it measures past .006". .001" to .002" is about ideal; there should be a touch of slop to avoid the binding you experienced when you shimmed.
