Federal's 7mm Back Country...

[Oso]

They say it's reloadable. Someone explain how that will work. I will wait.

Vortex podcast talk a bit about this. Ryan Muckenhirn took a tour of Barnes facility where they were loading cartridges, and briefly touched base on this process. Sounds like they’re using something similar to NOE plug to expand case mouth to initiate/facilitate seating the bullets. The metal is tough.

It sounds like there is no case flow into the neck so no trimming needed and no shoulder bumping required. They mentioned you are basically just neck sizing because the case goes back to original dimensions after firing. One case held up to five proof loads without showing any pressure signs :O that's insane!
Edit: They want you to only reload one case no more than 5 times because you will not be able to see any sort of fatigue signs since the Nickle plating covers the alloy and do not want any cartridge case ruptures.

Here's a you tube how-to from Federal on reloading:

 

[White Eagle]

so you get aother 7 mm mag but for a short suppressed barrel
steel alloy cases nothing new there have been alloyed cases before
I'll stick with what I have
if you reinvent the wheel it is still a wheel?

 

[AndyA]

black powder, smokeless powder
If you reinvent gunpowder it is still gunpowder.

That's pretty much it. There is a growing market for shorter-barrel rifles. Some prefer something for bushwacking, but I suspect the main market will be hunters using suppressors. For hunting (and the US Military), the biggest benefit of higher chamber pressure is that more work is done accelerating the bullet in the first few inches of the barrel travel.
I suspect that there will eventually be a market for lower pressure, brass-cased rounds. A lot of hunters don't need the full power most of the time and would be perfectly happy to get the extra reloads with brass. This way they can do more reloading for practice and shorter-range deer hunting while saving the high-pressure stuff for the occasional hunt at longer range or for bigger game.

I think we are already seeing this. There seems to be a trend toward scaling down rifles. Advancements in powder, bullet and case design have resulted in continuous improvement. At present, smaller more efficient cartridges are replacing traditional long action cartridges. Development of high pressure cartridges that can punch at magnum levels. Renewed interest in subsonic cartridges with focus on solid core bullet design and faster barrel twist.

Serious back country hunters will put up with the added recoil. Will us rank and file?

It's targeting the 18" barrel can users. I don't run a can. Reports show poor accuracy thus far, not even MOA in the majority of rifles. That high a pressure on my action, not something I would like to do often (realize most will take 100k plus). Always nice to see pushing the envelope but I have zero interest.

Please do not take this as a challenge. I am interested in seeing data on what certain actions pressures can consistently handle. I am stuck in the mindset of do not exceed SAAMI.

After reading this thread, I guess there is a niche for this enhanced round. That would be shots at extreme ranges. That would be ranges greater than what we now consider ethical with current loadings. I am not sure if increased muzzle velocity means increased accuracy/precision by the shooter at extended ranges. And yes, I agree, the Back Country round allows the use of a shorter barrel (less weight) while maintaining the necessary velocity/ft-lbs for ethical shots.

I suspect barrel life is not something that is good when fire 80k psi rounds.

A disclaimer. I have recently had major reconstructive back surgery and have taken my meds prior to bed. Please factor that into my comments above. Even I may not agree with them tomorrow morning. LOL.
