Recommend a powder funnel for 9mm

[armoredman]

Set the cases in the block mouth down, and turn them over as you put the powder charge in each one.
Then, set them down in a second loading block.

Exactly the way I've been doing it for a few years myself, just holding the case up tight to the plastic nozzle of the RCBS Uniflow. No problems, no spills, no fuss.
