In setting up my new RCBS Uniflow Powder Measure, I installed the smaller diameter plastic drop tube, as the instructions indicated it was for .22 to 7mm cartridges. I eventually removed it, as it was suficiently erratic as to be unsafe.
For instance, a down stroke might drop nothing, or maybe two complete charges. An upstroke might or might not drop something. Inbetween, small amounts would drop at different times.
I eventually figured out that the powder (4064) wasn't feeding reliably, and was stuck in the top of the drop tube. A tap or a motion would drop something, but seldom the full amount, and only the full amount, I wanted.
Putting the larger (.30 cal+) drop tube in fixed the problem for me, but this seems to be a dangerous oversight in a powder measure that newbies (like me) buy in a reloading kit.
Am I overlooking something, or is this something I should bring to the attention of RCBS?
