gravity loader nesting problem

[Siri]

We're using a gravity feed that slides into a 5-gallon bucket and is actuated into the shooter by a pneumatic cylinder. Almost as simple as it can get. We ran into jamming the night we put our full-court shooter wheel on (lots of vibration), but tightening up the mount and adding a section of metal tap measure (as a finger to hold the disks from vibrating into the shooter) seems to have fixed the issue. We may also slope the hopper slightly towards the pneumatic actuator if needed.
