I think
@NiteQwill mentioned these cups. I bought 2x dead drop cups, I cut/filled them to be the same weight.
I drop with a RCBS dispenser and finish the final throw in with the ingenuity. Running 2 cups basically means the ingenuity never stops.
Anyways the RCBS dropper always bounced a few kernels out of the glass cups. I tried protein powder cups and it was the same.
Anyways long story short:
2025 EDITION. The pour is very smooth with channeling features that help guide the powder into your case or funnel. AutoTrickler V3 “Dead Drop” Powder Cup.

Solved all my problems, a little expensive for a cup but for me, worth it. I did use a dryer sheet to clean out the inside of the cups, n555 was sticking, now it’s good.
