Federal New Cartridge

[khuber84]

Because if you had read, I am talking about short barrels. I want and many people want nice performance out of a short barrel. You keep harping on something else is better, you dont need this. Sorry but the 7BC on paper as I dont have one appears to give superior performance out of a short barrel. Why would I shoot a 280 AI out of a 18 inch barrel when a 7 BC out of the same length will give me better velocity? Oh because I am bull headed and dont like change. The protest about everything else is better makes me wonder. Could you show us on the rifle where the 7BC touched you?

I'm quite shocked to see so many manufacturers jumping into the 7bc, considering it hasn't and will likely not get saami approval.

A guy can do the same thing with virgin brass, load it so hot the primer pocket is toast in one firing. It'll likely be going the same velocity as the 7BC. None the steel or brass cases at this pressure are reloadable.

I'd be interested in seeing what the chambers headspace at VS the shoulder of the 7bc ammo. From what I've heard and read, ammo has pretty heavy primer protrusion from the case head, that tells me there is a lot of excess headspace. Have they designed brass on the small side to chamber spec to allow room for the super high pressure expansion buffer? This is the same reason why you can load virgin brass cases to quite a bit higher velocity than fireformed.

Saami approved it, I saw a video from the Shot show where the head guy mentioned it. The case is reloadable, Federal released a video showing that.

My guess is yet another very high pressure rifle round like the 277 fury. Seems to be everyone’s direction lately.

The 277 Fury is no slouch, don't think you will gain much going to a 284 bore unless you have a bunch of 7mm bullets on the bench. Maybe this new Federal round will breathe more life into the 277 Fury now.

The 277 fury gets 3120 with 150s in a 24” barrel so similar to 270 wsm/6.8w. Very fast for a 2.82” 308 sized case. The 7bc of course gets more with a bigger case. One difference is the brass portion of the case with 277. Apparently it is accurate enough the Army Marksman unit had Berger make the new 150 hybrid target and Sig is loading a 155 Matchking in facory ammo. I am not sure what precision to expect from the full steel Federal case. Maybe we will be surprised

I'll have to read up on this, I'm surprised they gave an 80k psi cartridge universal approval.

Resizing the brass was near impossible from all beta tester accounts a month ago. Something must have changed, alloy, chamber, die specs. Dies were cracking due to metallurgical resistance to sizing.

There are no rifles in hands of general public yet, correct? Just the gun writer propaganda machine. Will be interesting to see what real world results are.

If I could find the video I would post it up but I definitely saw it. I don't doubt they had issues with resizing but it sounds like they have a solution now. I'm interested to see what exactly they come up with.

Several of the companies said they have shipped rifles already. Again I wish I could find the video but that's what they mentioned. Normally I wouldn't have had time to look at all this but I was recovering from broken ribs. Was a nice distraction.

Was this the video? Maybe they've changed it as well, since this seemed to have no issue resizing (I heard the same "multiple passes to size" a while back as well).

Yes sir that's the one.

277 fury is very much reloadable. I'm still waiting to see more on this one. They say it is, so it probably is.

28 nosler will outrun the 7BC at any barrel length, so long as they are the same. So why not a 28 nosler?

Pretty simple. The 28 Nosler is a barrel burning and a dying cartridge. Nobody shoots it hardly at all because it never really did anything special. Next the Nosler was not designed for heavy BC bullets. After that it comes down to real numbers. Nosler out of an 18 inch barrel is not seeing impressive numbers. It might be at 3000 and will have an 80 percent powder burn with way higher recoil. So why would anyone think that was a win. Sorry but once again your argument falls flat. The 7BC seems to be a specific cartridge and it does that thing well. That thing is short barrels.

You forgot the part where it is reloadable. See Fed has said it is and RCBS is putting out stuff for it. Oh and you cant do the same thing with vigin brass. See taking a brass case up to 80 thousand when it wasnt designed for leads to bolt lift problems, extraction problems ect. So they are not the same and most of what you wrote was lets just say ill informed. So like change or not the 7BC does something new. It is pretty fast it appears in short barrels.

But you can.......ADG brass handles 70k psi just fine for multiple reloads. There's a certain someone who uses a 300rum, operating at psi high enough, his primer pockets are gone in one firing. His extraction is fine. I'm not advocating any of this madness but it's been proven it's doable.

Accuracy hasn't been great.

Federal 7mm Backcountry, Tested and Reviewed

We've shot the 7mm Backcountry more than anyone else and have the most comprehensive accuracy, velocity, and rifle data on this hot new round.

www.outdoorlife.com

I'll likely never own a 7BC, because I'm not much a 7mm guy, I'll pay enough attention to this cartridge just to see how it shakes out from the hype VS real world performance. Gun writers 95% of the time are paid, sponsored, schilling. Very few tell it like it is, the above article actually used 20 shot group data. And it was 2 moa

What I want to know is what is it about this cartridge/thread that makes people become mentally handicap?

While I won't be buying one until the dust settles, I am quite excited about the potential of high pressure rounds in general and the shorter barrel that can come along with them.

Your argument against 28 nosler vs 7BC is exactly my argument for 280ai vs 7BC. They're almost the exactly same arguments. It's the whole reason I went to 28 nosler for the sake of argument, because I figured you'd make my exact argument against it. And I completely agree. 7BC makes way more sense than 28nos. For more or less the exact same reasons 280ai makes more sense than 7BC for the vast majority of hunters.

I'm glad you've come around to the higher recoil being a factor.

There's nothing magical about high pressure rounds in short barrels. Other cartridges can achieve the same velocities, just with more powder since they don't have the pressure. The only advantage high pressure rounds actually have is in recoil. Which is a really really big factor. If you can get the job done at X distance with less recoil, why wouldn't you? The individual has to determine what X is, but we all know that for 99% of people it's inside 675 yards. Way inside.
If people were more honest with themselves even 280ai doesn't make a lot of sense when 7-08 exists.

I think I need to do a 6.5mm or 6mm fury with all my hybrid cases I picked up a year ago.
