55k psi 65k psi 70k psi and now this

Pretty sure there is a thread on here about this already.

I read and commented yesterday (or maybe the day before - cant remember)

Wow, a bullet that wipps out of the barrel 3500 fps + is incredible. 300 blackout or 6.5 creedmoor taking out better pressures has its advantages for sure. My understanding is that the throat takes a beating, along with the rifling of the barrel, but the key takeaway is the bullet casing technology. So brass is too soft for pressures after 55,000.00 Steel casing has its limits as well maybe a Nickel alloy mix bullet two piece shells. So two things comes up pressure from the rear of the casing at the primer and the outer wall of the bullet expanding. The concern here is the shearing of the internals of the rifle its self from exploding at pressure at 100,000.00 + hense reinventing the shell casing technology.
 
Brass handles 65000 psi with out to much problems.
Maybe one day they will find a barrel material that is better for those high pressure cartridges in terms of longevity?!?! Stainless is supposed to be a bit better than chromoly but I don’t think by much, maybe they need to work on barrel longevity for the future of those rounds. For me anything over 5k rounds is way more than I would ever need.
