7mm Federal Backcountry

This article discusses a little bit about reloading it, a little bit of heavy bolt lift.

Compared to factory ammo, I think their claim as being the fastest is probably valid, at least neck and neck with 28 nosler. Factory 28 nosler with a 195 berger is advertised as 3000fps or less out of 26" barrels (copper creek, unknown munitions). Federal is claiming 3k from a 24" barrel. This guy's testing seems to show their claimed numbers for the 7mm bc are valid.

Let's compare apples to apples if he's claiming 28 Nos performance at 80,000 PSI well then what is then whenthe 28 Nos at 80,000.
You can easily run a 28 Nos at 3050 with 195's in a 26" barrel. I would bet good money it won't run that with 195 in a 26" my guess is more like 2900.
The reason the Nosler factory ammo sucks is because Nosler sucked at there reamer design.

Not picking on anybody, but................
Lol, yeah, picking out those that don't give money to the site will surely get them to contribute. (Sarcasm) We don't pay for social media, the advertisers do that. See how this site is plastered with advertising...same deal. Do you contribute to google, or any other site you extract data from?

Something to be considered. Wasn't actually trying to guilt anyone into being a contributor, merely making an observation.
 
I read that RCBS is working on dies for the new cartridge. They are having issues resizing the alloy.
From the article above.

None of that sounds like this will be a reloadable case so far, and the powder is also unobtanium so far as well.

Keep in mind, the DoD could care less about reloading, so if they are targeting the DoD requests with a steel cased higher pressure round, then let it roll.

Not sure how this unfolds for civilians with carry weight hunting rifles but time will tell.

I think the bolt lift is because the brass flow and bolt thrust. Steel cases dont do that atleast thats what they are saying. All the videos released seem like the guns in 7 bc work like normal rounds
Then you tell that to the bullet and ammo makers I've been at the shops for meetings who are dealing with it.

Two different places and both are using a hammer to open the bolt. So....? This is on Remington actions and on a ARC action. The one place said the ARC action is running better than the Remmy but still using a hammer on it. Now this was with hybrid cases. Not all steel.

If I recall correctly the one video they had hard bolt lift or if you will the double clicker happening.

As the saying goes you cannot fool mother nature. In this case physics. Action designs will need to be improved.

Also fouling from what I've been seeing goes up also. To the extent you need to clean the barrel about every 30 rounds or so to hold accuracy. A hunting gun... probably not a big deal... but for a shooter who has intentions to use it in competition.... than what?

I haven't seen a single person mention anything about the barrel steel. As a safety factor the steel has about a 2-1 safety margin on normal working pressures. Now increase it to 80k... your losing your safety margin there also. I will say here also... pressures go up, heat goes up, barrel life will suffer, fouling goes up and if accuracy suffers with certain bullets etc... who is covering the warranty? The bullet maker? The barrel maker? The gun manufacturer?

I'm going to be blunt about it here... till I see more data on all of this... calibers like this we warranty nothing. Not in terms of fouling, accuracy, safety etc... too much beyond our control.

You want to go fast.... as my best friend Dave always says... It's going to cost you to go fast! One way or another.
 
Now this was with hybrid cases. Not all steel.
Thats probably why they arent using hybrid cases. Try that again with steel and report back. Unless all the videos online are lying and not actually shooting the 7 backcountry, they dont seem to be having problems. If it wouldnt cycle im pretty sure federal wouldnt be putting this out. Or did the manufacturers they partner with for guns change something specifically for this?

Don't know.... but I'm going to sit back and watch and get data from the ammo makers when I can.

We made ammunition pressure test barrels for Federal. Those are 2" breech diameters keep in mind.

One ammo/bullet maker I talked to.... they are watching this also.
 
Definitely bring up a good point on safety factor. If trying to maintain the same the actions need to grow in size i would think
 
Here is an interesting and seemingly pretty unbiased review after building and testing a number of rifles in the 7mm Backcountry. Looks like there is more work to be done as their results aren't the greatest. Accuracy just isn't there yet, contradicts the long range accuracy promotion.

 
I like seeing new cartridges come out. It’s interesting and keeps our sport alive and moving forward. Keeps us talking about the new stuff and comparing them to the old. I have yet to see a new cartridge that stops me from doing what I like to do… :)

With that said, I’m guessing the 7mm BC isn’t made for reloaders, Federal, an ammunition company, designed this for the guys that don’t reload. Good for them and I hope it’s a huge success.
 
So, would'nt this new round be considered one of the first new
endeavors of the Czech's who now own Federal. If so, would not
this cartridge fall under CIP, and not SAMMI for published data ??
Not real sure, how that would work with ownership.....
 
This thing isn't any different than the 700 yard capable cartridges that we have now, that are limited by the 400 yard capable rifle they are held hostage in. Now we have an 800 yarder in a 400 yard gun. You need a rifle that is capable of putting the bullet on target at the limit of the cartridge. Nothing has changed as far as off the shelf rifles that would make this cartridge any more effective that what we have now.
