cast some bullets , keepin em seperated which from which cavity , drill 1/8 hole in em 1/4-3/8 " deep then screw in a 8x32 screw tap.
Hold the bullets with the mold if ya feel comfortable with the drillin `round it
After ya get it all together wet the cavity & sprinkle some comet powdered cleaner on it , enuff water & comet to make a slurry lay the bullet in the mold & close but enuff to start spinin the lapper.
The hi spots will become apparent real fast .
As ya get the slurry worked in & close the mold more check often to see that lead & comet is`nt holdin the blocks from mateing .
I use a makita cordless drill on slow speed & drill enuff bullets to have 5-6 / cavity.
Fine lappin compound is more aggresive but will round corners qwiker !!!
Go slow & methodical & all will work out fine !
When the cavity is shiney all over all te burrs are gone .
The cavity will reblue more & more after each use , just take care of it between sessions so it does`nt rust !!!!
As far as "smokin" a mold I use a butane liter , matches have wax in em & leave undesirable deposits , aso the graphite sprays deminish bullet dia !
Hope this helps even if a little
