That's what it said in my book , I use Paradox P and a .357 case with a paper clip soldered on it for a power measure , but i can't remember if i filed any thing the end , to get the proper measure , i always load on the high end 15 grainsok made a little progress
threaded cap on 'top' of measure
locks brass plunger at increment setting
then you swing spout to side and
fill at spout end
think we've got it
manual says 12-15 GRAINS
of FFFG
that sound right?
