I ordered a fire lapping kit from NECO that has #220,#400,#800 and #1200 grit.This is nothing like valve grinding compound and doesn't embed in the rifle steel.It cost about $75 by the time S+H and exchange at the time.I have 90% of it left.Came with two small steel plates for rolling bullets on.The owner can give you pistol powder loads for whatever caliber you're doing.I could sell what 's left.............Harold
