About Us

J&M Spec. LLC is a group of veterans, reenactors, competitive marksmen, and firearms instructors dedicated to making the best, most realistic, and most reliable snap caps / dummy rounds / fake bullets in the world.

J&M Spec. LLC is an A+ Rated BBB accredited company which has been in business since July 2018. We sell to individuals, firearms manufacturers, museums, Federal Firearms Dealers (FFLs), and film prop companies.

We started with one caliber, .308 Winchester, for our WWII reenacting unit’s (the Kelly’s Zeroes, Dahlonega, GA) 1919 Browning machine guns. This quickly expanded to 30-06 in order to teach those new to the M1 Garand how to operate it, both for reenacting and for competition in NRA and CMP Games matches. It has all grown from there. We now make snap caps for more than 320 calibers and gauges, making this the largest selection of inert cartridges / dummy rounds / snap caps available anywhere in the world!

We are constantly expanding our selection of dummy ammunition / snap caps / “fake bullets” that we manufacture for military, cowboy, and commercial calibers and gauges. If there is a caliber or gauge not listed on our site that you are looking for, please give us a call or send us an email. We would be more than happy to research manufacturing dummy rounds for it.
