I too am runnig seat crimp in one die along with the lock-out die. It works ok with lead if you have consistant bullets and have the die opened/ polished enough to work. I use plated with no problems. That being said all of my friends that ask I tell them with the Inline Fabrication bullet tray it is just as fast. I made a cover out of 2 layers of neoprene gun cleaning mats to quiet down the bullet feeder otherwise it was too loud to run non stop and acttually slower than hand setting bullets. If you do not have the case feeder yet get it first then maybe consider the bullet feeder but lower your expectations over what the case feeder adds to capacity.
