New High Pressure 223/Cases

[Oso]

I came across this YouTube video on new ammunition, Shell Shock by Badlands. The Shell Shock case is manufactured from stainless steel and designed for 100k psi. In the video they use a couple of brands of commercial ammo (brass cases and new Shell Shock)) firing both 55gr and 77gr ammos through AR15’s with various length barrels.

https://youtu.be/FODsQaaJXJA?si=h0kFacP6-pMcyzHk
The Shell Shock ammo (55gr) is +300fps as compared to similar conventional ammo (brass cases). The difference in the 77gr ammo is only +100fps. This is less significant, but also misleading. With the 2.26” mag length restriction and the 77gr bullet there isn’t enough space to add extra powder to push toward higher psi. I think a reasonable expectation would an increase in velocity when Shell Shock is loaded long with 77gr SMK, providing more room for powder.

Food for thought… reloaded fantasy.

Yeah well steel cased 223 is nothing new if you wanna/need to start pushing things....
Russian Barnaul has been around for years, 62gr SP projectiles and Zinc plated steel cases.

Used the last of 20 gifted years back just yesterday getting a new to me rifle on paper....they all went bang.

The High Pressure Wars just got insane.
An AR capable of 100K psi ??????
ONLY 300 Fps. for an additional 40 K Pressure ??
Marketing Marketing Marketing!!!!!
I'd like to see the disclaimers on this stuff.

The cartridge case may be able to take 100kpsi but can the bolt lugs and receiver?? 100kpsi is in all directions within the cartridge case including to the rear. Also,what about the bullet withstanding that much pressue....copper & lead? What do think the muzzle pressure would be?
Good luck and stay safe.

That's why the question marks.
Case is doable. The rest I have to seriously question.

Ha! Read slowly and think: “designed for 100,000” . Doesn’t say it operates at 100,000.

Many years ago, our military found that steel cases would allow for extremely high pressures. Generally in modern bolt guns, brass is the weakest link. Steel just didn't function well and barrels didn't last as long.

All fair comments. I’m sure we’ll learn more as ammo gets rolled out over time. What is actual pressure that is generating additional 10%-15% increase in velocity? What is the reduction in barrel life… looking forward to someone figuring out these types of questions

Another observation from video on the Badlands Shell Shock ammo was the respectable low SD’s for a factory ammo being shot out of several different AR’s with various length barreled (10” - 16”).

As was said the rifles are not made for those pressure levels. If you buy the cases do you have to sign a release stating they are not responsible for injuries?
