Mr. Bulletfeeder Caliber Conversions

Stock Number: MRBCC
Conversion kits are available allowing you to use your Mr. Bulletfeeder by Double-Alpha for more than just one caliber. Many reloaders have a second complete tool head for their 2nd caliber of choice, voiding the need to reset the dies.

To make the transition easy, the Mr. Bulletfeeder by Double-Alpha conversion kits includes a complete dropper assembly, a custom powder funnel for pistol calibers (this is not included or needed for rifle calibers) and a new collator plate for the caliber of choice. This will allow you to switch your bullet feeder from one caliber to the next in a matter of minutes.

Rifle calibers require using boat-tailed projectiles.

The spring output tube securely attaches to the top of the dropper by means of the Spring Adaptor Cap, which attaches and disconnects easily from the top of the dropper. The inner threading grips the coils of the spring firmly, preventing any chance of it coming loose during operation, and allows a quick transition from one dropper to the next.

Please note: All pistol calibers use the same Large output tube assembly, 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.

All rifle calibers (223,30cal) use the same Small output tube assembly, and so when converting from 223 to 308, the same output assembly is used. As previously noted the rifle caliber kits do not include, or need, the custom powder funnel so you will have to supply your own powder funnel.

However – if you intend to buy a conversion kit to convert a rifle unit to a pistol caliber, or from a pistol caliber to a rifle caliber, you must purchase the appropriate output assembly required, in addition to the conversion kit

The expanding powder funnel supplied is for the Dillon reloading machines setup in pistol calibers only. Not compatible with other brands or any rifle calibers. To use with the LnL press, you will need to purchase their expanding powder funnel separately.
