Doing some more watching videos on this and I see that most use a fiber wad over the powder and compress it over the charge. This is followed by a thin paper wad to prevent the fiber wad from sticking to the bullet which is understandable from an accuracy standpoint.
One reloader stated that he put a thin paper wad at the bottom of the case to prevent powder from entering the flash hole. Is this really necessary?
My last question is on bullet seating. Should the bullet be in contact with the wad/powder and how hard should it be crimped?
