The Mini Mr.Bulletfeeder by DAA uses a 6-tube magazine system which holds roughly 100 bullets. It feeds into the same brilliantly reliable dropper die assembly as used on the Mr.Bulletfeeder.Using a Mr.Bulletfeeder while reloading is a real pleasure. It makes the reloading process faster and much easier. If you have never used one, you are missing out on one of the greatest reloading assists out there! A Bulletfeeder also improves safety, by preventing the need to insert your fingers under the tool head to place your bullets on the brass. Everyone should use one!
