CAMBRIA COUNTY, Pa. (WTAJ) — Concurrent Technologies Corporation (CTC) has been awarded two patents for a revolutionary ammunition design that will benefit U.S. warfighters.


CTC was awarded two patents for "shell case design utilizing metal injection molding," the company announced. The patents detail the invention of a single-piece, high-strength metallic cartridge case that is stronger, stiffer and lighter than traditional brass.


The design was a joint development between CTC and the U.S. Army to "improve warfighter effectiveness through increased lethality, improved accuracy and reduced ammunition weight."

The company said several cartridge calibers have been demonstrated with distinct advantages over competing solutions, such as hybrid metallic-polymer and multi-piece metallic cartridge cases. The metal injection molded cartridge benefits include:


  • 30 percent case weight reduction vs. brass
  • High-pressure capability, up to 100 ksi tested
  • Increased muzzle velocity, up to 10% over brass
  • Increased accuracy (sub-MOA [Minute of Angle])
  • Durable stainless steel case material with reliable functionality from -65°F to 160°F
  • Rugged, single-piece design with no corrosion issues
  • Compatible with existing brass case taper, trim, load, assemble, and pack manufacturing infrastructure

U.S. Patents 11465207 and 11493314 not only protect the U.S. government's ability to organically produce and supply this technology to the warfighter but allow cost reduction and maturation through private commercialization, according to CTC.


"This award comes at a time when global commodity prices for copper and brass are at all-time highs. The use of high-strength, lightweight stainless steel cartridge cases in ammunition production reduces manufacturing costs," CTC President and CEO Edward J. Sheehan, Jr. said. "The CTC team has done an outstanding job of analyzing requirements, developing a solution, and ensuring it is cost-effective and scalable."

Additional cost savings the CTC mentioned include:


  • Reduced fuel and transportation costs from cartridge weight savings
  • Easy firing range cleanup due to cases being magnetic
  • Reloadable for consumer and competitive shooting

The activity that led to this patent is part of CTC's overall ammunition and weapon systems engineering services. The shell casing design inventors are Todd Skowron, Juan Valencia, Shawn Rhodes and William Brueggen.

Man I'd have to worry about sticking cases. Must have some sort of special alloy to still allow it to expand and grip a chamber, this after all, is what keeps bolt thrust/lift, manageable on higher pressure loads. Interesting for sure. I wonder if it can be annealed similarly to brass cases to keep the neck from splitting after a few reloads.

I'm guessing since it is a steel product that it will be the opposite of brass. It will get softer with each reload. Heat it up to make it hard enough?

Heat and quench to harden steel--- wonder how many reloads you can get on one case? Will they have new nitrated dies so the ss won't scratch the inside of the reloading die?
