Hello...I'm new to the board, and new to reloading.  I have a question about deburring flash holes.  I have the Sinclair tool that indexes off the case mouth with pilots.  How deep should I go with the cut?  I'm not sure how far into the case to insert the tool; obviously, the small cutting end needs to protrude through the flash hole, but I don't want to cut too deep.
