Here are the pics for feeding systems for bullets and cases. Here’s the collator of bullets, it picks them up, flips them if facing pointy end down, and sends them down the feeder tube.
Here’s the sensor attachment. It sits above the feeding die and when the bullets stack up to this level, hits interrupt sensor and motor stops. I wanted smooth and steady motors so I picked up 12v, 5rpm motors off of Ebay. Bonus of a 5rpm motor is that due to the gearing reduction is has loads of torque so I can put a lot of bullets and it goes like a champ.
Same principal applies to case feeder. Although a little easier to get the cases oriented the right way, as they don’t stay in the pockets since the base of theirs is so much heavier.
