First, many thanks for all of the replies.

Brass is new Hornady with no bevel on leading edge.  Here is photo of inside of side plate.



Here is my interim solution, a custom made Krag "stripper" clip.  I fill the clip with the rims aigned so that each succeeding cartridge rim is in front of the preceding cartridge.  So far no problems at all quickly loading the next five rounds.
