Reloading for the new .277 Fury from Sig

You can buy 277 sig fury ammo now on the sig website. They have all brass cased ball ammo at "normal" pressures and higher pressure hunting ammo the hybrid case. I dont remember the velociites exactly but think the hunting ammo was a 150 accubond at 28-2850 out if 16" barrel and something like 3100 fps out of 24".

That's nice for Sig to supply us with proprietary stuff. But what about us loaders that would rather do it for ourselves?
 
The civilian version won't be rated for 80,000 psi
65-68,000. Ballpark Sammii won't allow 80,000 psi in a civilian firearm thats wishfully thinking
You can buy a rifle chambered for it and hunting ammo that appears to be well above what's possible with more standard pressures (uses the new case design for 150@3120@24").

I'm not familiar with exactly how saami works, what sets the limit on case pressure?

The design limits of the gun and the material limits of the case as used. Also the bullet construction has to be considered. I'm not a firearm designer or engineer but I would surmise this is relevant.
 
Saami pressure for round is 80k. They have an extra warning about it saying may need special case/gun design vs traditional 65k max. It is in the spec on their website. Curious to see how others support this but I doubt compettition will let sig be only place doing higher pressure, especially with so many guys moving to short barrels for suppressors

Is this 80k pressure limit for this round specifically, or a overall limitation on all rounds. I wonder what kind of reload ability those cases will afford with all that pressure.
