However, Paul's proposal is to load to greater than established (SAAMI) pressure and OAL. That effectively makes the proposed 6.5 Grendel MRLMG load a new cartridge which requires as much or more development and proofing as competing rounds like 6.8 SPC w/long-ogive bullets, or Cris Murray's 7 UIAC and 6.86 UIAC.
That the 6.5 MRLMG load requires a lead-core 130gr (or heavier) projectile, when the US and other armies are fielding unleaded bullets, and many other nations use steel-core bullets, causes me to question its viability.
If all that wasn't enough, there is also the complete lack of terminal effects testing with military-type ball projectiles.
Agreed - especially the lead-free bullet issue (whether we like it or not). The US Army are uninterested in ballistics achieved with lead-cored target bullets, they want EPR-style bullets.
Incidentally, this site has a feature which I really hate - if you're rather tired and not concentrating, the obvious button to press after you've finished typing a response is the big "Reply to Thread" button. Which has the effect of wiping out everything you've just typed and leaving you with a blank reply form. Yup, this is my second try at responding, and is a lot shorter than the first!
