Mean Assembly Tolerance pass 0.005/0.006 hold, measured with rear gage in place
Max. Acceptance after proofing pass 0.008/0.009 hold, measured with rear gage in place
Customer Service Maximum pass 0.009/0.010 hold, measured with rear gage in place
If you don't have Go HS gages, take the measurements with sized empty brass in every other chamber.
