4. The steel case can withstand 80,000 PSI (SAMMI spec is 65,000 psi). That DOES NOT MEAN that firearm actions, barrels, suppressors (especially suppressors) are designed to withstand repeated 80,000 PSI pressures. Seekins has already come out saying that they will have to redesign an action to accommodate this cartridge.
Seems like they are just chambering it in a bunch of existing actions because bolt thrust with 80k PSI on a standard bolt head isn't any more than the SAAMI 62k or 65k PSI across the larger area of magnum bolt heads. I have no idea but the whole high pressure cartridge reference by seekins on their new 3 lug actions felt like as much a marketing explanation as anything else. I dont understand why they went all weatherby with stacking their lugs on the 4 lug havak actions anyway if that isn't at least as strong as the basic typical 2 lug actions that are going to get chambered in this round.
