    Only a few were using the 338 Lapua. The new ASR rifle by Barrett is to be a 300 Norma with the 338 Norma as the anti material round. For the common knuckle draggers this is a big step up from the 300 WM. But it's one of those "be careful what you wish for" things.

    "this is not the 6.8 from a decade ago, it is something totally new with performance close to a 270 Winchester short mag." WOW

    Each company submitting has their own cartridge. What absolutely doesn't make sense is to get the performance they want pressures are running 80K PSI. NOW WHAT COULD GO WRONG?

    Nineteenth century technology for a twenty first century war. Meanwhile the bad guys are still using AK47s and RPGs. Military intelligence, the original oxymoron. More taxpayer money pissed away to keep someone in a job.

    Is that why the cartridge shown has a steel base?

    Interesting read. Aspects such as materiel damage vs anti personnel - had not thought of that differentiation.
    The 6.8 dia? Never could figure that. But as I follow, I'm finding out even more I didn't know or had even considered.
    The 80k pressure figure - I'd like to do some reading on your info source Dave. Hope you won't have to kill me after you tell me. :)

    Nah all this is open source. The 6.8 supposedly is the smallest diameter that lets them develop all the different projectiles needed. There's always one requirement that drives these things. They needed 80K psi to get to a level of performance to defeat level body armor at 600yds. Sounds simple enough but if 80K is normal operating pressure then the system has to function when pressures are 90K+. There's a gov document somewhere but I haven't been able to find it yet.

    The thought crossed my mind that 1000 years from now, military historians will be talking about the Creedmoor, and not a word will be spoken about the other 6 and 6.5 chamberings. Creedmoor will live on ...........
