Why would I build another rifle or spend a grand on barrels and bolts when I could just use what I have? Plus I can shoot cheap Norma match all year unlike any of the magnums
I'm going to laugh my *** off when they do this to the 7mm Rem mag

Depends on distance. Out to 500-700, probably not. If you keep shots to 500-600, then 300fps won't matter.
But higher speeds = less wind drift. Wind is the greatest unknown downrange effect.
Higher speeds = higher impact velocity at distance. Meaning stretching distances for minimum impact velocity for proper bullet expansion. 250-300fps can add 200+ yards to that maximum effective range.
I couldn't care about less drop at distance. That is easy to overcome by a few more clicks on the turret.

More likely 80k psi.My guess is that pressures will be close to 67K psi plus. Any info on primers? What will conventional primers look like at high pressures to get another 10 -11 % more velocity?
Same steel as used in nuke reactors ! - what's next - U235 or Plutonium fissioned ammo (better than R26).
Would not be surprised to see ammo recalls.
As for primers, I tested the .277Fury Hyb brass in my 20" .260AI vs Alpha SRP brass.
Alpha SRP w. H4350 = 2984fps w. 130 OTM max w. slight ejector marks and just a hint of bolt lift
Fury Hyb w. H4350 = 3186fps w. 130 OTM, no bolt lift, just a hint of cratering but still rounded primers.
I'm sure it's been posted but what do you guys think, think it's safe in the average rifle, and a 308 on the way should make things interesting.

My complaint about the 6.5 Creedmoor was that it was somewhat whimpy compared to older cartridges. But I read 3100 fps 130 grain on those Federal boxes!!! If that's true, well then, the Creedmoor has been turbocharged.
Using the NAS3 cases with 308 at 80k psi.
3 firings
WLR primer.
I started to post this info but felt like I was hijacking someone else's thread.
I recently received a batch of the NAS3 cases in 7.62x51.
As people have stated, these aren't really reloadable so far, but I wanted to test them with a few different bullet/powder combinations and see how they do.
My fired case capacity is 60.85 gr of H2O.
First ladder test is with 175 LRX and Varget.
After calibrating GRT for powder lot: This is what it's showing:

It needed this.

The 308 imo will be the ultimate game changer, a 20inch bbl with similar performance, then the fact of the ar10's, scars, and countless others, along with mass availability with performance to match a 300 win, that's next level stuff.
130-140 weight class at 3400+ fps.
