Get an additional 6-tube Magazine assembly for your Mini Mr.BulletFeeder by DAA. Each assembly will allow you to preload another 100 bullets before you start your reloading session.
Be sure to keep the assembly upright once filled, to prevent the bullets tipping out the top holes. Align the hole in the base of the unit with the tube which has the retention pin in place, so all 6 tubes can be filled. Remove that pin only when the assembly is placed on top of the dropper die assembly.
