6.5 Needmoor ~ Federal +Peak

You cannot change peak pressure without altering the heat energy of the system.
Physics fact!

The Federal +Peak cartridge uses the exact same physical volume as a standard 6.5 Creedmoor case. You physically cannot fit 15% more powder into it.
onto Chemical engineering....
To jump from 62,000 psi to 80,000 psi within the same volume, Federal uses a faster burning mix combined with heavier powder compaction.

In thermodynamics, PRESSURE and Temperature are.directly proportional
aka IDEAL GAS LAW ( PV=nRT)

You aren't burning more fuel, you are burning the fuel way faster and tighter. This causes a massive spike in peak temperature and gas velocity, which is why it cooks steel barrels so quickly.
You are robbing barrel life (Peter) to pay for extra velocity (Paul).

I would agree with this but in thermodynamics you are comparing the same material( water) … not all powders burn at the same temperature. Imr7828 is well known to burn at max pressure with a substantial decrees in temperature. So as soon as you change to a faster burning powder you can’t compare to the 4350 the standard load is using.
Federal says barrel life is comparable to standard loads. Time will tell

TIME does.tell a.lot..
but so do numbers and current tech in rifle making and materials especially some of the garbage off the shelf.

Standard 6.5 Creedmoor @ 62,000 psi @
2,500 – 3,000+ @ 1 barrel
versus
Standard 6.5 PRC @ 65,000 psi @ 1,100 – 1,500 @ 1 barrel
versus
Federal +Peak 6.5 Creedmoor @ 80,000 psi @ Estimated under 500 @ 1 barrel.

PHYSICS says there is a change.
and Barrels will change with it.

How’s the barrel life on these 7mm backcountry? I think there will be a huge difference between a hunter doing the odd 3 shot string a few times per year vs a competition shooter putting 15-20 in a short time frame many times in one weekend. I think we’ll see target shooters sticking to the old ways, but there’s definitely some gains for hunters here.

I didn’t see any benefit in switching to the 7mm backcountry when it came out unless I could run a suppressor because we can get similar performance with a longer barrel in canada, but I can get behind this suped up creedmoor. This made me a believer in this new tech.

to answer your question...
7mm is ground.up development...
completely different animal—it is a brand-new, stand alone cartridge geometry built from scratch..

You cannot just buy a box of 7mm Backcountry and shoot it out of an old rifle. It requires a dedicated 7mm Backcountry chamber. Federal partnered directly with rifle manufacturers like Weatherby to build factory rifles with dimensions and barrel steel optimized to withstand that 80,000 psi plasma torch right out of the box.

verus

The 6.5 Creedmoor +PEAK line is designed as a pure ammunition play.

Don't buy a new rifle. Just buy our expensive steel ammunition, put it in your standard 6.5 Creedmoor, and get instant 6.5 PRC magnum velocities.

It utilizes the standard .473" bolt face and existing rifle chambers. This makes it highly enticing to the average guy who wants a massive velocity boost for a weekend hunting trip without spending $1,500 CAD on a new rifle setup.

The consumer takes on all the hidden costs of accelerated barrel burning on their existing rifle just to shoot a premium factory.

One is built.with finesse and safety...the other has pulled out all the stops!

For those curious. Here is the information I found about the cartridge specific to barrel wear.

how does federal use case design to prelong barrel life +11 Federal® uses different case design and material innovations across its product lines to enhance performance and protect your firearm's lifespan. Depending on the type of shooting you do, Federal specifically engineers cartridge cases to minimize gas cutting, reduce thermal wear, and contain high pressures.Federal targets case design and barrel life through a few core mechanisms:1. Peak Alloy Case Technology (Centerfire Rifles)In cartridges like the 7mm Backcountry and 6.5mm Creedmoor +PEAK, Federal uses a patented, high-strength steel alloy rather than traditional brass.Extreme Pressure Containment: These steel cases can safely handle pressures up to 80,000 psi, allowing for magnum velocities using smaller powder charges and shorter barrels.Insulation Effect: Because the Peak Alloy case is incredibly strong, it acts as a containment vessel that insulates the barrel throat from the extreme heat of the burning powder, reducing the "plasma torch" gas cutting that eats away at rifling.No Case Growth: The steel cases exhibit significantly less stretch and growth than brass, which minimizes the throat erosion caused by escaping gases.

Increased pressure over CIP level, will that mean we need to re-proof? Will this ammo get CIP approval?
All the years on here I was told it has nothing to do with the case design, material or wall thickness when it came to increasing pressures on a 6.5x55.

Huh

What a pile of there ! There gonna Tell you what You wanna hear

Seems ironic that in Pride Month they're trying to may the 6.5CM less ghey.

 

[cptseawolf]

Only time will tell on barrel life.

And it's not like federal would just make a cartridge that blows everyone's guns up.

Will be interesting to see more details as it comes out.

But as a military ammunition specialist (Ammunition Technical Officer) this stuff makes me nerd out.

 

[DGY]

Me and that is only me, I don’t get it. People that wanted there 30-06 to shoot 200fps faster they bought a 300win mag…. I wonder what is the real reasoning behind that new 6.5cm, I mean I get it that you already have the rifle on hand… who owns only one rifle anyway!
I guess now they can say to everyone who said that everything the 6.5cm does the 6.5x55 did for over a 100 years shut the fyck up bltch… hahaha

 

[257Wby]

It will be interesting to see what primers are being used with the Peak ammunition pressures.

 

[Slimbo]

Good news is 99% of hunters will never burn a barrel out even if it only lasts 500 rounds

I dunno man, I talked to the guy who designed the technology. These are smart people. I for one am very excited to try it.

Estimated by who? You? Based on the ideal gas law? Care to share your math? Because I just ran some rough numbers and from what I'm seeing the PRC would actually have LOWER temps than the CM, when calculated for both peak pressure reached at 1.5" of barrel and 3" of barrel. Yet we KNOW the PRC is harder on barrels. Only if you assume max pressure is reached without the bullet leaving the case does the PRC have higher temps.

	PRC PEAK	6.015	56 grains	0.1618534	80000psi		2193

And yet we KNOW PRC goes through barrels faster. So Temp alone isn't the only thing to consider here.
