Well, someone will go back to the old trials of using various coatings or liners inside bores, and with modern advancements in materials and applications, we just may see that. A lot of mil and civilian bores out there are plated, and many years (decades) ago we played around with TiN, ceramic, varied chrome platting, etc, but the results were less than acceptable. Today, who knows?
So reverse anneal using the same process
But only in a 338 Lapua sized action. A Rem 700 wouldn't just shear the bolt lugs off, you could shoot the rifle like a LAW take out tanks with the bolt blowing out the back
Aw c'mon, I thought my sarcasm was evident!
At 100k psi someone will have to build a more robust action!
Are there no modern actions that can handle 100k psi?
First off I am wondering how we can have a shortage of copper ? Where did it all go in a world evolved around recycling. I have recycled copper wire, etc for years. I worked in junkyards so the wire was for the taking. Pennies are no longer copper. And even the copper in old appliances are recycled. The only conclusion is we shot the copper world into the ground. lol I live near a old copper mining town. Perhaps I should educate myself and start digging again ? Is there really a shortage ? Or is it just what they want you to perceive ? They seem to be real good at this. The diamond market comes to mind.Johnstown earns patents for revolutionary ammo design

CAMBRIA COUNTY, Pa. (WTAJ) ā 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 -65Ā°F to 160Ā°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.

Most/all of them should be able to, at least once. The safety margins in the designs is pretty large usually. But if the pressure level was common they'd need to over-build to a higher margin.
