Just a tip for the Mr. Bullet feeder(MBF). I use the MBF to load 9mm, 38SPC and recently started loading 380 Auto. While loading 380 Auto, the projectiles would turn and then get stuck in the dropper feed spring and in the top of the dropper assembly of the bullet feeder because they are a shorter length bullet. Fixed the problem by using the 223 dropper feed spring because the spring has a narrower diameter, the projectiles don't turn and get stuck. Also, don't forget to relocate those BB's and clip to the lower slot because of the shorten bullet length.
