You can use your Mr.Bulletfeeder PRO for more than just one caliber, switching over quickly and easily with the help of the readily-available conversion kits. These kits include all the parts needed to switch your bullet feeder from one caliber to the next in a matter of minutes.
A Mr.Bulletfeeder PRO pistol conversion kit includes a PRO collator plate, a full PRO dropper assembly and an expanding powder funnel. The Rifle conversion kit includes the PRO collator plate, a full PRO dropper assembly, and a small output spring assembly. No powder funnel is included with the rifle calibers, as those cannot be used due to the small size of the case mouth.

NOTE: The Dillon XL750 Powder Measure is angled such that the powder bar must extend directly over station #4 in the toolhead, and it cannot be repositioned. This Is not an issue if you have a short die in that station. However, if you wish to run a powder check in station #3, and a bullet dropper in station #4, as many do, this creates a serious problem. As a solution to this issue we are pleased to offer our Extra-Short Dillon Powder Bar. (sold separately)

Please note: All pistol calibers use the same output tube, lead spring and spring adaptor cap. So this assembly is not included in the conversion kit –as you will not need a second one when changing pistol calibers.The rifle calibers too share the same output assembly and so when converting from 223 to 308, the same output assembly is used. However – if you intend to buy a conversion kit to convert a rifle unit to a pistol caliber, you must purchase the output assembly required, in addition to the conversion kit
