Actually I got it to drop one at a time. Loaded 200 rounds without an issue. It may just be a fluke, but I made tiny adjustments to the die height until it worked. Also, made sure there was no interference. On a 650, the powder hopper will sometimes touch the MBF die. The bullets have beveled edges which may be enough for the die to work. I'm using hard cast hi-tek coated bullets from Chey-Cast. Sent from my SM-G965U using Tapatalk
