100,000 PSI?

Very interesting.

 

[SJB358]

That’s a game changer. Wow.

 

[Charlie-NY]

Think about what can be achieved with a larger case.

 

[FOTIS]

30-378 200 gr at 3600 fps?

The biggest problem with steel based cases is they are not forgiving like brass. Much of the same as nickle coated cases. In a dirty environment something has to give if dirt enters the chamber, will it be the case or the barrel?

Will they be selling a. barrel with each 500 rounds.

I had a little Yamaha RD 250 back in the day. Racers would outdo the 750's with them. But they rebuilt the engine for each race.

Pass

32” of drop at 500 yards is pretty impressive. A 75gr boattail at 3500 fps sure would flatten out a PRS competition range, and lighten the rifles a good bit. I’m thinking a progressive twist barrel would extend barrel life for civilian rifles.

 

[highoctane]

Interesting to say the least, however, don't think it's for me tho.

 

[JD338]

I'll take a hard pass on those pressures.

I’m recalling the failure to Crome line the chambers of the early M16 A1.

 

[8mm Enthusiast]

Questions that come up are: reloadability, how clean does it burn, barrel life, and if the extreme velocities will cause copper bullets to pencil through animals without expanding.

I think this could eliminate the need for a new service rifle. I think we are going to see a lot of this in the Future.

 

[Ralt71]

The 7mm Backcountry concept.. and they have been in testing for a long time on the military stuff. I thought 120k was the ceiling in this as well.

 

[Joe C.]

I’ll bet we are all using electric hydraulic presses to size and deprime before it’s over. Maybe not for everything, but steel cases seem to be where things are headed. I also wonder if they are using primers specifically suited to the pressure. What the headspace specs are as the case doesn’t expand like brass cased ammo. I’m curious.

I think us reloaders will have a lot to learn when these newer high pressure bullets start hitting our AOO. There is no doubt that if this concept takes off and is successful everyone will follow suit, just like they did with the 60'ish thousand pressure mark way back in the day.

 

[West Fork]

The video doesn’t mention about any effect on suppressors. Maybe wrong, but I think 100k psi in something like the Backcountry will be hard on suppressors.

And if we think that handloading has become expensive in recent times with our current cartridges, can’t wait to see what it’ll cost with this stuff….

Cost of ammo—factory or handloads—will probably limit the general shooter’s adoption of this new ammo.

 

[IdahoCTD]

Higher psi also means heavier parts/thicker materials to sustain the pressure. That defeats some of the benefits of shorter barrels and the trend towards lighter rifles.

 

[Joe C.]

It’s entirely possible that they weren’t designed as being immediately reloadable. If it’s not reloadable the factory controls supply and demand, that equals price and who gets paid.

I do have a question. Do die manufacturers have to pay royalties to market and produce dies for a wholly patented round. If so that will influence cost on that end. Most rounds patents have expired.
