Another new cartridge.

[Yorkie]

Well, another new cartridge design to throw into the mix. I doubt if i will be reaching for the variation form. Make of it what you will.

The 7mm Backcountry from Federal. Steel alloy case to handle pressure. 'Federal is claiming up to 3150fps with a 155 grain bullet from a 20", yes 20" barrel.

Savage are chambering rifles starting at 16.5 inches and up to 20 inches.

The 7mm Backcountry is Federal’s newest rifle cartridge promising to “reinvent ammunition.”If you saw my review of their 30 Super Carry, which they called

Sounds great, but what problem does it solve? Like the 6.8 western, interesting, but aimed at the domestic US market I suspect because of restrictions elsewhere. Let’s see.

Can it be hand loaded? If not, it will go the way of the Dodo.

What’s wrong with a 30-06? 110g to 220g

No elk will walk away from a well placed shot with 180g partition, even at 400, if one really couldn’t be arsed to get closer. Throw a 220g up the spout if you’re worried about bears or mothers in law.

110g if you’re feeling frisky for rock chucks with friends and a bucket of cold Budweisers in the pickup

 

[Smellydog]

I'd rather have a bucket full of 06 and you keep the Budweiser, I don't have any friends....

It's just marketing.
It'll catch the imagination of the young.

Who amongst us are not guilty of that....

 

[cjm1066]

As a marketing name Backcountry doesn't roll off the tounge or seem posh/sophisticated like Creedmore.

It will be interesting to see how the steel case performs.

Amongst the plathora of 7mm cartridges spotting the difference is becoming like the old spot the ball competitions.

Back country, broke back, back passage. You filthy animal! And I thought too exactly the same association.

Back on topic.
I struggle to understand how a steel case will increase the pressure capabilities.
To my understanding it is the weapon‘s chamber that will have to bear the stress. The case is just a container in between which can‘t go anywhere. Am I wrong?

 

[JockStalk]

If it’s not better than anything else with copper then it’s shortly to become irrelevant in the uk.

It’s just another variation on the .277 Fury

What burns out rifle barrels and will the 80,000 psi of the SIG .277 Fury burn barrels faster than ever?

I think it will dodo even without handloading.

 

[Tazz]

Sounds like another Creedmore Fad

Yep. The cartridge is the weakest link.
Actually, the higher the pressure the easier on the bolt or lock up. But the case head and primer are the weak spot.

The steel will supposedly handle the pressures better than will brass cases? So less failures at the head of the case from the primer pocket expanding? Brass being less robust than steel?

I can see a role for the thing in, say, a twenty-four inch barrel "sniper" rifle in that the firer can zero at XX or XX distance with the 10 gram aka 155 grain bullet and know that the bullet between zero yards and eight hundred yards will be within four inches rise or fall of that zero they have set? Or even if that's ten inches rise of fall say between zero yards and one thousand yards that is still admirable performance.

Hi.
Cases are re-loadable apparently. Looks like a 280 remington running at 80,000 psi.

Steff,
As Smellydog mentioned the case (brass) is the weak link & typically fails first (primer pocket/head area). There’s plenty of photos available showing what happens when the then unconstrained gas wreaks havoc on the rifle action.
