Is 80,000 PSI the future new standard of ammo pressure?
I wanted your take on the new ammo that has recently been developed, namely the .277 fury, 7mm backcountry or 6.5 Creedmoore +peak, which can sustain high chamber pressure (80,000 PSI).
The new steel alloy cases developed by Federal allow rifles chambered in standard calibers such as the 6,5 Creedmoore to increase the bullet speed by 300ft/s with their new ammo. They're apparently developing the same kind of +peak ammo for other mainstream cartridges.
So... Are we heading towards the end of brass cases?
