Thanks @jackieschmidt. I have wondered about this. So have you found a decrease in accuracy going from let’s say .002 to .003 or more?In most cases, yes.
In past years we were ate up on extremely tight clearances, thinking it enhanced accuracy. Much of that line of thinking come out of the old Houston Warehouse experiments when full length sizing and upper load window loads were non existent.
Most agree now that it is better to have a little too much clearance than not enough when it come to overall agging capability in the real world.
