While working on improving primer feed options by enhancing primer chute/trough pin contact with frame column groove rings for SPP/Pro 6000, I had a thought.
The primer chute/trough feeds primers reliably yet it's the primers hanging up in the tray that we are trying to improve.
So what if we just eliminate the tray and extend the chute/trough length?
Using Costco apple pie plastic cover, I made a primer chute/trough rectangle tube extension with Styrofoam cutout base taped to replicate Lee primer tray bottom. Extension tube 10" long held over 50 Winchester LP primers.
This is how it looks inserted into the primer chute/trough and of course, it was 100% reliable without any concern of pin making sufficient contact with frame column/groove rings (I removed the pin for testing as it was not needed). With an adapter at the top to accommodate Lee primer tray, you could refill the chute/trough extension rather quickly.
Next I wondered if I could make the tube open "V" shaped to accommodate 100 LP primers.
So I arranged the LP primers in the primer tray into a "V" and measured around 3" across at the top of primers.
I extrapolated the top by around 0.5" and new "V" shaped primer chute/trough was around 3.5" from top down to bend at the bottom
But when I inserted the open "V" tray into the primer chute/trough, weight of primers pressed down on two primers at the bottom and bottleneck jam was created.
So I am thinking about making a channel guide/ladder ramp to test next to flow primers but since rectangle tube extension works 100%, perhaps two or three tubes merging into one may work as well.
