Its going to make my .270 SING!"It's the work of satin i tell'yah".......OR, coming from the most litigous country in the WORLD, then maybe it just works as it says on the box?
Federal is Launching 6.5 Creedmoor + Peak Ammunition - 80,000 PSI !
- Thread starter UpNorthMI
- Start date
No....thats the point is it not? It'll work within the confines of ONLY modern chambering? SAMMI and all that good stuff.
Federal definitely not going to entertain older calibers were tolerance, design and materials possibly won't meet the standard.
Ps. Not dissing. 270
Smelly is absolutely correct, you’re bonkers if you believe that a 0.25mm thickness open ended steel tube is going to contain 20k PSI!
Why do you think the 6.8x51mm US NGSW uses a hybrid case with a steel head? It’s because brass will yield at 4500+ bar limiting the maximum pressure.
It would be interesting to see how much pressure margin is built into a SAMMI / CIP 6.5mm creedmoor bolt and action?
I’ve not studied the NGSW XM7 bolt in detail however I spotted a picture of it the other day and it looked particularly beefy, certainly more so than a standard long action rotating bolt.

I understand this bit…..You don't even understand what you just read
So Federal are going to knowingly produce high pressure ammunition that will chamber and fire in any rifle with the same cartridge designation and it will not be safe?
I don’t believe you.

As I mentioned earlier, from speaking to Federal's UK importer, forget getting CIP approval. UK stock is years away!!
On the plus side. Speaking to Viking, they would likely look at getting the CIP approval done themselves, although that's assuming the market demand will be there... Which given the extended lead time, should let them get a good idea of how the Americans react to this latest fad.

You shifted the narrative.
Our tobacco trader member said that the case will support the chamber or words to the effect of boosting the chambers capacity.
It won't.
I don't give a hoot about the chamber pressure. I push service pressure and loading data more than most on here. But blurting out total twoddle if not correct.
You asked ai a specific answer leading it to give you a biased answer. That's not particularly clever or substantial. It just gives an argumentative **** a shallow argument.
The steel case is nothing new. In this example it is there merely to support the unsupported part of a case that the service envelope is being pushed. End off.
Go dig some better **** up to support your and your tobacco trading friends point.

So what would they be used for in UK ?
Lead ban.....
Wont be allowed on MOD ranges ...
Dread the think what it will cost per box
But i do enjoy reading the bullshite .
For a kick off there claim it will out run a PRC is total Tosh . the ammo that they
claim faster is a 130 grn bullet and there putting up against a 143 grn hornaday varmint express
Most PRC shooters will tell you is not the fastest , bit like most of the factory stuff .
Maybe they should put up against a 6.5 prc with the same 130 grn bullet .
Mine will clock 3300 fps
By all accounts there is an ever growing list of manufactures stating its not suitable for use in there rifles.
In there own words ...
" While compatible with most modern bolt guns, semiautomatics, lever-action rifles, there are a few important caveats "
Thats all i need to know

With respect, you obviously don't. It is just fluff saying the case will continue to protect the chamber in the same way as the current brass one does, just at greater internal pressure. Nothing more and nothing less.The increased strength is in the case itself to contain the increased pressure, which will in turn protect your chamber. Duh.
It is not saying it will dramatically add to the hoop strength of your chamber, and it simply won't. Well, not to any degree worth arguing about anyway. Smelly and others are right.
Google is not the manufacturer, and Google is totally unreliable for technical research. Use it as a starting point only.
My Chamber needs protecting?Thanks, But NO thank you.

So, this is coming off the back of the 7mm Backcountry - a new cartridge designed for 80k psi use, Who’s intended use is to get long barrel performance out of a 16” barrel with moderator. But they have had a lot of teething problems. The main issue is the increased pressure is playing havoc with accuracy - rifles chambered in it are very hard to get shooting small groups. They think it’s the high muzzle pressure upsetting traditional bullets. There have also been chamber tolerance issues, extraction issues, needing extremely expensive reloading tools (yes it’s possible) and only some actions are recommended for it. It’s new territory, probably in 10 or more years it’ll be more user friendly but currently the pros are dwarfed by a multitude of cons.
In the meantime it’s actually pretty common nowadays (as in, not unheard of) to reload traditional brass cartridges up to 80k psi, accepting poor brass life and being careful which action is used. I would not do it, but that doesn’t change the fact the blokes doing it have shot huge amounts with no concerns. Some of the issues carry through, but overall it’s a much simpler and more well charted area.

Would be interesting to know how many of them wear proper ballistic eyewear.
Its not a new thing , it goes back many years longer than any of us . Fancy to guess once the not very forgiving steel blows up with your mush a few inches from your face ? We don't need faster , most shooters cannot even shoot 300 yards with a brisk wind .Wouldn't have thought you were aflag waver

If the steel case was going to do the job on its own there would be no need for caveats.
