Welcome to J&M Spec.

Makers of the finest, most realistic dummy rounds available.

We are a group of veterans, reenactors, and competitive marksmen dedicated to making the finest, most realistic INERT display or “dummy” ammunition available. We specialize in military cartridges of the 20th century and Western / Cowboy calibers as well. All of our dummy rounds are made using REAL cartridge cases and REAL bullets, giving them the most realistic weight and feel.

Our products are used for a wide variety of purposes. Our customers include reenactors and museums trying to create the most realistic display possible to educate the public, collectors and individuals with personal firearms displays, professional and amateur gunsmiths alike, and even folks in the film industry. Don’t risk the safety of your display, use our Realistic Dummy Rounds for all your firearms displays or training.

The list of calibers are divided into a few different categories to assist you in finding them. Many calibers are listed in more than one category. These include:

  • Calibers by Country – look for the cartridges you want by the nation that made and/or used them.
  • Rifle Calibers & Pistol Calibers – subdivided if there are multiple options for a specific caliber.
  • Commercial calibers – those designed for and used in modern, commercially available firearms, and not used by any nation’s military.
  • Western Cartridges – For all the Cowboys out there. The perfect addition to your “Wild West” collection.

Please feel free to contact us! If you don’t see the caliber you are looking for on our website, please let us know. We are constantly expanding our inventory list and are always open to new ideas.
