Just as a fyi to anyone following/reading this thread.
I've told the guys in the office here....that we will not chamber/install any barrel for a customer in this caliber.
I will not warranty any barrel from copper fouling, accuracy, safety etc....
Anyone installing one of our .270cal barrels and having they're gunsmith and or themselves chambering one of our blanks up in this caliber.... again at this time No warranties will be covered etc...
Could my feelings change on the above? Possibly but at this time no guarantees.
Last I heard was the 80k psi ammo will not be available to the general public. Doesn't mean some will not get out there.
Also I totally see someone tinkering and playing with this round and go... "I'll just load it up until I get to 3000+ fps with a 140gr bullet!" but they don't and won't have a clue as to the pressures they are dealing with and the safety margins in components can be compromised.
We've made a lot of ammunition test barrels in both accuracy and pressure and the data I've seen so far has me to be on the cautious side of things.
