Well just because it would be a .277 and not the imposter .284 7mm/08. But the couple of grand to do this just isn't going to be "spare pocket change" any time soon.

You might be onto something
I'm keen to see this technology applied to other calibers like .223.

Too late it's been done back around 2006 called the 270 Redding never took off should be able to find dies and reamers second hand

I'm guessing he was referred to the hybrid case technology, as opposed to the shortened case.

Yeah the case is cool, I read somewhere that the hybrid round costs the military US$5.00 each
what would retail be?

Im not positive his conclusions stack up.

The standard cased fury ammo shot slower than 270 and if you gave them a similar barrel length there would be nothing in it. Likewise I suspect any advantage would disappear if you gave the 270 win a steel head and shorter barrel.

Yeah but the pressure limit is part of the SAAMI/CIP spec and so you can't give a 270 Win a steel case head and ramp it up to 80,000PSI without re-submitting it and calling it something new like "277 Furious Barrel Burner".

If you don't use full pressure 277 Fury ammo then you essentially have a 270-08. You'd forgive a 270-08 for not quite hanging with a 270 Win, the same as you wouldn't expect a 308 to outperform a 30-06.

With full pressure ammo, the 277 Fury in the 20" Cross seemed to slightly outperform the 24" 270 Win. Of course if you compared full pressure 277 Fury to a new 270 Win-esque 80K PSI hybrid, you'd expect the 277 Fury to get spanked.
