I started with pickup tubes, then used a Vibra-prime for a while. Picked up a Rf-100 a few months ago. I love it. Next to the bullet feeder on my 650 it is one of my greatest time savers I have in my reloading arsenal. It took about 3 tries to get my machine working like a champ. The only issue I have is using S&P primers. It eats winchester, CCI, Tula, and federal without a problem. It is a wise investment if you want to save time.
