DAA Mini/Mr. Bulletfeeder Die Ball Bearings (set of 3)

Keep your Double Alpha Academy Mini or Mr. Bulletfeeder working at its best with this set of three die ball bearings. These small, caliber‑specific steel balls fit inside the dropper die of the bullet feeder. They help hold the stack of bullets and allow one bullet to drop at a time into your case during each cycle of your reloading press.

If you ever take apart your dropper die, the tiny ball bearings can get lost because they fall out easily. Having a spare set means you can replace worn or lost bearings and avoid feeding problems that slow you down. These ball bearings come in different sizes for common calibers like 9mm, .40, .45, .223/5.56, and .308/7.62, so pick the size that matches your bullet feeder setup.

This set of three bearings is a low‑cost part but an important one because it helps your bullet feeder die function consistently. Whether you are maintaining an older feeder or just want spares on hand, these die ball bearings make sure your reloading runs smoothly without unexpected issues.
