A LOT of people reload brass cases to well over 65kpsi. All you have to do is look at a lot of claimed velocities here.
7MM Backcountry issues?

Federal has already published all load data and powders.
That's good. I still want nothing to do with it! I think it's a flash in the pan.
If I'm wrong and its still kicking in ten years I'll be surprised. I think it will be like the Win Super short Magnum cartridge. Know anyone shooting them?

I'm sure you're right. Probably like invention of the wheel, gunpowder or the brass cartridge case. There were people that thought these were just like flash in their musket pan. Yes I still know people shooting the 270 and 300 WSM. I never owned one but have nothing against them and they swear by them.
He's talking about WSSM. That's a very generic reply saying that all new things have naysayers and comparing the 7BC to the wheel and to gunpowder, two of the most important inventions ever.
Whoteewho has one he has been shooting. As far as generic reply. That's your opinion and you have a right to it just like I have a right to mine. I do believe the new cartridge is going to change things. In my opinion it's the biggest change since the brass cartridge so I don't see it as generic at all. I could be wrong but so could you. Time will tell.
One more thing of note:
I had a 6.5 creedmoor cartridge go WAY over pressure this last fall. It was a handload that came from a guy who I bought some brass from. My fault. Never shoot someone else's handloads.
This a mild cartridge that had the exact same effect on the rifle.
The WSSMs failed because they failed "to feed". haha
Not the best comparison.
If the new case material can make the bullets go faster. It is likely going to be used.
I'll bet we see 5.56 cartridges using this peak alloy next. Then prob .308. The hurdle is the SAAMI spec. which, I believe is why they made a new cartridge instead of starting with an existing one.
Very interested to see how this develops.
Also: I have a couple of the WSSMs and the 223 makes a great varmint round. Goofy, for sure though.

Hi Russ,
I've done some work with the 7mm BC and other high pressure cartridges. The proof loads for the 7BC are at 114,500 PSI and I have shot that out of standard Remington 700 actions. There is no lug setback or other issues even at the proof load pressures.

If you didn't know what the Winchester Super Short Magnums were then you haven't been shooting long enough to lecture me!
Nowhere in this thread have I said that the 7BC will fail. I mean your answer was generic as it could apply to any almost criticism to almost any product. Brushing off criticism by saying that people probably doubted the wheel and gunpowder as a defense for the 7BC is as generic as it gets.
If you want to offer some sort of defense, explain why it will succeed. I mean it's been out for a year-ish and we don't see any copycats or anything else suggesting momentum. If you want to say that suppressor usage is going to take off bc they will not be considered NFA items anymore or something like that, have at it. Does it solve problem other than allowing a short barrel with the velocities of a long barrel for those that want to use a suppressor?

I see the 7BC as the first step in higher pressure loads for future development. Every new idea/product seem to have issues that need to be refined.
Some endure while others wither on the vine. I remember when Remington first introduced primer-less ignition rifles. That didn't seem to last very long and no one else jumped on the band wagon. Some forward-thinking ideas just don't pan out.
I hope the high-pressure loads work out and we all have something new(er) to look forward to.

Well the 277 fury pre-dates the 7BC. I wouldn't call it a success commercially, but there's 1 example of similar. Then there's the NAS3 cases in 223, 308, 300blk, 380acp and 9mm. They seem to be gaining some traction.
So are there more high pressure cartridges suggesting momentum? Yes, there very much are.

I always find it interesting on these 7BC threads that they're the best thing ever…and I've yet to see any groups posted up. I've seen plenty of Chrono numbers…but no groups.
Have you reloaded the cartridge yet?
