There have been multiple stair-stepped iterations of pressure increases in the cartridge firearm industry over the last 150 years. Luddites can pretend nothing new will last, but reality has proven that each of these pressure standard increases have sustained. The new 80kpsi frontier is simply the next step in that evolution.
Driving a Model T or shooting a black powder rifle cartridge in 2025 is nostalgic, but it’s a long way from the state of the industry. 50 years from now, shooting a 50kpsi cartridge will be akin to shooting a 45-70 today.
As consumers of cartridge firearms, we’ve been employing 7mm cartridges which push a 170-180 class bullet up towards 3000fps for generations already - this performance standard solves a lot of questions many of us ask. Doing it with 50% greater barrel life, less recoil, and lower powder consumption is a win.
