This .082" drill bit is the correct size to uniform LARGE PRIMER flash holes.  This size was advised by one of the major primer manufacturers.  Using this drill bit some flash holes will have a lot of metal removed & others very little, possibly none.  Consistent ingnition is only attained with flash hole diameters all uniform.  Even within the same lot of new brass suprising variations can exist.  Once you have drilled all of your flash holes you will have more uniform ignition.  Additionally this will help to eliminate the problem of the decapping pin sticking in some undersized flash holes.
