I do the charge, and seat method when loading rifle as well. Makes things go quickly that way. No need to wait a long time. By the time I have a bullet seated the next charge is ready.
I use a Hornady Auto Charge it works well. Mine was gifted. If I were going to spend my money I would probably go with the Lyman.
I admit I am a cheap skate from the old school. I would never have spent my money on one. Now that I have one if it stopped working I would buy another.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
