9mm duplex cartridges

Bought these at a gun show years ago, private company was selling them. Designed to be used in a silencer with two bullets. Do not know what kind of powder was used but understand that these cartridges worked.Attachment 125677Attachment 125676

Both bullets from a duplex will usually hit the target within two inches or less between them.

I used to load a duplex with 45/70 and two round balls...that was exactly what happened. Both balls would hit within a couple inches.

Remington manufactured 2 million 45-70 multiball cartridges during 1917 as old Springfield trapdoor rifles were being
re-issued to guard various military installations
