Can someone recomend wich FL sizing die with neck bushing I can use for a Dasher. From what Ive read I can have my reamer run into the forsters ultra seating dies sleeve,of a 6br) to use for the dasher, but what should I use for shoulder bumping and neck sizing. Redding? Ive also read conflicting things about neck bushings and donuts. what do you Dasher guys use to expand the neck for the false shoulder THANKS!!!
