Lee Precision AUTO INDEX CLAMP

I too bought this index clamp as a spare to go with my Lee Classic Turret Press. Before ordering my press, I called both Lee and Graf's, and asked what items might be prone to wear or breakage, and they were very helpful. Better to have it and not need it, than to need it and not have it!

I don't know if you can actually wear this part out as I haven yet, however a spare on hand is always a good idea.
The square clutch that goes inside it may wear out eventually so I keep a couple on hand. They are small enough to loose in a cluter if need to disengage the auto cycle.
