Federal 7mm backcountry?

Just watched a short video and then read a couple articles. Anybody out there familiar with the alloy cartridge case
? I can’t seem to find much info about it. Curious if it’s reloadable and if they will make other cases. Thanks!

Forum Boss: This new cartridge has a steel alloy case and operates at a very high pressure. The idea was to offer higher velocities in a hunting rifle with a relatively short barrel. I see it as a gimmick... but the concept does have promise for the military.

They have an FAQ lower down on the Backcountry page that answers some of your questions. They do say it will be reloadable.

I just went back to the website and checked it out more. cool cartridge. can't wait to see what's next. Thanks
 
Not reloadable yet. Supposedly it takes about 12 passes through a sizing die just to get the shoulder to move.
That was my first thought, was thinking hmmmm those cases sound like they'd be very difficult to size. Even if say for the most part they don't need sizing, at the least, I'd think you'd need to size the necks and wouldn't that present the same problem if they didn't or wouldn't size and just sprang back. I mean how the heck would you control neck tension....
 
I'm wondering why they decided to do the entire case in this new alloy as opposed to just the case head like the 277 Fury. A brass body with an alloy base would make reloading way easier.

Yeah and not to mention about doing an anneal. May need to break out the
mini argon furnace. I wonder if the people at AMP are scratchin' their heads
yet......I'd like to get my hands on at least one case to play with.
 
Have to imagine that barrel life is rather short lived. For the individual that shoots 20 rounds a year,I may see the appeal. For the shooter that fires over a thousand rounds per year from this single rifle this cartridge Is likely to consume throat at a faster rate than most may tolerate.

Barrel Life would really need to surprise me in a positive fashion for me to get on board. Very un-likely.
 
At first I wrote this cartridge off. I just watched about 3 hours of interviews and podcasts flying home last night, I think this peak alloy may be a bigger hit than I first imagined. Several Manufacturers are chambering rifles now for the 7BC, from Savage to Gunwerks and many in between, 14 manufacturers or more. Advertised velocity is checking out. Bolt lug set back after several hundred rounds is no more than many of the big mags we shoot now. Barrel life is longer than I presumed. It’s early but I’m watching with interest now. Federal will have load data up soon, it uses the same primers, extracts fine and is reloadable so they claim. I’ll try and link a couple of the more interesting podcasts that I watched.

Like I said, I wrote it off as a marketing ploy when I first heard about it but I’m rethinking things and watching with interest now. I won’t buy in anytime soon, I’ll let others be the guinea pig but there might be something to this.

This year we hunted pretty hard, back country, rough country. Our rifles had suppressors and 22.5” barrels. I was using a thunderbeast 7, it’s just makes for a very long rifle and didn’t fit in my pack very well at all. It was getting old.

I just took delivery of a 6.5 PRC with an 18” brux barrel today, I’ll be comparing it to the same rifles with a 4.5” longer barrels over the next couple of months so I can see the numbers for myself. I’m also having a 20” 7 Saum improved being built as we speak. I’m hoping to get 2800+ fps with the Saum and a 180gr Berger. If your using a can and your migrating to shorter barrels the 7BC actually makes a lot of sense, I’d love to get 3000 fps with a 170-180gr bullet and a 20” barrel.

I think it was 1925 when cartridges started hitting 65k PSI. There really hasn’t been anything earth shattering since. Yeah, lots of new cartridges but they all are limited by the brass, you can only push it so hard. If this peak alloy does everything they claim I can see it being used in other cartridges and I can see them expanding the cartridges they offer. Imagine a 223 operating at that pressure, imagine what a 24” barrel would do in a .284 with a 180gr bullet if a 20” is getting 3000 fps. I’m not promoting it because I have no idea what it’s all about but I am keeping an open mind. This might be a pretty cool step in the history of centerfire cartridges. I‘ll stay on the sidelines and watch with interest for now.

Imagine the poor soul that puts an 80 kpsi round in their AR .
Stupid is as stupid does, but you know it will happen.

I'm gonna let you n Zack figure it out, when you do, I'll look at it.
I know both of you hunt with cans and want the shorter barrels, whereas I'll take a longer barrel without a can cuz I'm half deaf anyway.
It's the alloy case and resizing that is gonna be the hurdle to make it appealing for most.
Wondering if a standard rock chucker is up to the task or if specific tooling is gonna be required to accomplish it.
If it will fo 3000 from 20", 26" will be impressive

I watched a ton of videos on it. Lots of blah blah blah but also some good info and points of view. I’ll sit on the sidelines for a bit And see where it goes but it definitely is more interesting to me now than it was a couple weeks ago.

And then will come the day you 2 will get that wild hair. Lol
This I want to see and I'll just wait patiently ;)
