Huntsman22, I looked around and it looks like Sinclair has a similar set up for sale.
They have a steel adapter that screws into the Uniflow measure. Then you slide a clear acrylic drop tube into the adapter and set it with a screw.
The drop tube is pre made with the correct size hole in the bottom, rather than a grey plastic unit like yours.
Might be just what I need.
Seems like Sinclair has a good reputation on the internets, yeah? Never used their products before.
As it stands now, I drop the charge into a pan and dump it into the case using the .17 funnel from RCBS. Its really not all that slow.....I must just be impatient.
That is a very good funnel, never spills a kernel. Next step would be to cut it off and tape it to the Uniflow.......
