Federal 7mm backcountry video

[fseaman.js]

I have a problem with the claim of 80kpsi
I have a lot of experience with primers. They will start to blank at 70kpsi. With Remington 700's the blanking is quite worse. Most need the firing pin turned down and bushings installed when pushing pressure.

But that is "normal" for lots of builds or as an eventual maintenance item.

I wonder if the two cases are identical one of them just has nickel plating? I would think primer flattening and primer flow would still be a sign.

They are signs, but not good enough (some primers are softer than others)

Better bullets is to be determined…..it's a steel case so once they make the die sets to reload them I'm betting they will be outrageously expensive………but with the case being steel you shouldn't need more than a neck sizing die because the case will be formed to fit your chamber perfectly

I am not sure about how many firings will take for the steel case to be formed to fit the chamber, it has a lot less ductility and malleability than brass

Here is a new federal backcountry reloading video.

I am not against a new cartridge option, but in this particular case, I have a few serious questions:
1. What is the use case that was not already covered by an existing cartridge, maybe even better (e.g. if you want a fire-breathing dragon, you already have the 28 Nosler, if you want an out-of-the box gun+cartridge that shoots very well, you have the modern, optimized 7 PRC and the true/tested 7 Rem Mag, if you want an easier shooter get the 280 AI or even the 7-08)
2. barrel life at such elevated pressure
3. unnecessarily complicating the reloading process because of the choice of case alloy (fire forming difficulties, way less pressure signs, special dies to handle more rigid cases, trimming complications, "flaring" needed for the case mouth to avoid bullet's tail deformation, neck tension and concentricity control, etc.)
...
It seems to me that Federal's main goal was to create a cheaper factory cartridge with forgiving ballistics and good enough accuracy mostly for long range hunting () with low shot count. It seems reloading was just an afterthought.
I trust Federal did their homework, being a reputable company, but only time will tell about end users' adoption.

He said several times during the video, in effect, We don't have dies or details on the reloading process, but we will. "The cartridge is absolutely reloadable"... but not today, says the R&D manager.

That is not a very convincing video. Do any of ya'll remeber when Remington came out with Etronx ammo? It was about 25 or so years ago, so many of you won't remember, but it had an electric primer. It was wildly expensive and short lived.
I suspect the 7 Backcountry will be too. Today it is NOT reloadable. Until it is reloadable it has no chance of survival and if or when it becomes reloadable, it will have to be a better mousetrap to stay alive and make it worth the "stringent process" with non-traditional methods and equipment.

Any one of the other 7mm cartridges that I can load for that will get me to ~3k fps in a 20 - 22" barrel will suffice.

Yes those of us that know will have this.

Factory rifles are going to be an issue

Yes I am old enough to remember the electric 22-250. Fastest lock time known to man.
In the grand scheme of things reloaders are a super small percentage of shooters. On this site a non reloader is probably very rare. From a nationwide perspective the average deer hunter doesn't reload.
Time will tell if this new technology flies or not, but I can see the average guy buying the new "super 7 with steel cases".

Are you being sarcastic? The silencer central banish backcountry was made specifically for that cal and rifle configuration and it's the best choice but every dead air nomad series .30cal will work…. Silencer co makes several models that will work but why would you want a caliber specific suppressor buy a .30cal so it's interchangeable

Just a question here....other than just one company stating they have made one design to work with this pressure....do you think it would be safe to screw on ANY OTHER can? There was an article here just a few days ago about cans blowing up... with Normal loads.

I have tons of questions especially why do you have to expand the mouth like a straight wall case? Do you have to crimp? We know nickel cases send debris down the barrel what is going to happen when these coatings start breaking down? Why reload only the premium case that is coated on both sides? Is that coating going to last very long? If this is your cup of tea go ahead. Too many possible issues for little gain. I don't see the suppressor being that great of an addition to hunting set up to offset the cost. JMO. Did see a video of a custom built 7 prc vs 7 BC and the 7BC out of a custom gun could not produce 1 MOA

You only should load the PREMIUM CASES BECAUSE THEY COST FAR MORE!! And I couldn't agree more with you....Far to little gain..but there's always the folks that will drink the Kool aid...to have WHAT'S STYLIN TODAY! One of caliber, probably months wait for specialty dies with specialty casings that I am guessing no other company in the brass production would be able to afford to tool up for.... with a melting point difference of 800 ° F..... A one of case...just me...time will tell.... but I sure won't be buying one! ...and I know that means nothing to anyone else...
