The original screw was a slotted set screw. Screwed in flush, the reason it is there is it closes the channel leading in to the powder chamber.

It is not really a clean out screw, during manufacture they had to connect the flash channel to the powder chamber and drilling is the easiest method. The best way to close it is a screw. It makes for a great cleanout plug.

Lyman list the screw as a cleanout plug Part number 6030123.

And it is NOT a round head screw.
