New 7mm cartridge from Federal

With some of those and a scope with a reticle that looks like a screen door you can hit mooses/meeces at 2K yards.

I'd much rather a 28 Noz. Better performance in all bullets

Backcountry | Federal Premium

Federal’s 7mm Backcountry is an entirely new high-performance, all-range cartridge that reinvents ammunition as we know it. It not only provides superior ballistics and terminal performance, it does so through compact, shorter-barreled suppressed rifles.

Thanks for the news. Thanks for keeping us up-to-date on the latest.

I noticed that they did not compare their new cartridge to the big 7 mm's. I am pretty sure that I can guess why.

I'm going off of a weak memory of it but what I believe it was called 277 Fury ? It had a ceramic case ? I don't remember the details . Was it designed for military use ? Were the cases reloadable ? I wouldn't think so but what do I know ?

Didn't HK come up with a cartridge that was made out of cardboard or something like that. The cartridge would get incinerated in the chamber, and there was nothing to eject. I never saw one. But I remember reading something about it. I think it was in the 90s. My first thought is what happens to the primer? Is it made up something that gets incinerated too?

Sounds like a recipe for carbon buildup in the chamber...I wonder if it was semi-auto?

One thing I want to clarify on this discussion is they are not using the old "steel cartridge case".

They're using some kind of stainless alloy, so everyone's past experience with steel cartridge cases should be thrown out the window.

I don't know anything about the material properties of this alloy myself, but it certainly sounds like the ductility and toughness properties are different from the old steel cases.

When I get a case, I'll hit it with our PMI (positive material identification) gun and let you know what materials are involved.

PLEASE do!

I think that it was select fire. I thought it was a military weapon.

 

[HRM Johnny]

Oh yeah, I agree. What a great way to build up large amounts of carbon in the chamber. For whatever reason, it obviously never caught on.

Probably their HK91 (military version G3) and HK93. 7.62 and 5.56. I had an HK91. Awesome rifle. It had fluted chamber to assist in pressure for blowback. It sucked for sizing cases. Not sure if they still do it.
Don't know why I told you that. Just sparks a memory I guess

 

[WYO300RUM]

I haven't heard a reply on the ceramic case 277 Fury. Maybe it was non pertinent. It might not have been 277 Fury. CRS Steel case head and brass body. 6.8x51 I guess.
Not on topic. I know. What's new.

That's interesting. I'd like to hear more about this.

As the thread here kinda belongs to Fedral I'll hijack it with this question, does anyone have one of the POF rifles with the fluted chamber and how does that affect resizing and carbon?

My HK 93 with fluted chamber mad sizing cases a PITA. Yes , chamber would get filthy but it never caused a malfunction on me. Sorry, I not recognizing POF.
