    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.

    A Collector's View - The SMLE Short Magazine Lee Enfield 1903-1989. It is 300 8.5x11 inch pages with 1,000+ photo’s, most in color, and each book is serial-numbered.  Covering the SMLE from 1903 to the end of production in India in 1989 it looks at how each model differs and manufacturer differences from a collecting point of view along with the major accessories that could be attached to the rifle. For the record this is not a moneymaker, I hope just to break even, eventually, at $80/book plus shipping.  In the USA shipping is $5.00 for media mail.  I will accept PayPal, Zelle, MO and good old checks (and cash if you want to stop by for a tour!).  CLICK BANNER to send me a PM for International pricing and shipping. Manufacturer of various vintage rifle scopes for the 1903 such as our M73G4 (reproduction of the Weaver 330C) and Malcolm 8X Gen II (Unertl reproduction). Several of our scopes are used in the CMP Vintage Sniper competition on top of 1903 rifles. Brian Dick ...

    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.
