New Army "Caliber Configuration Study"

[cory]

The question is, would 6.5 Grendel w/108gr bullet be outranged by 7.62x54R w/148gr bullet, when 65G is fired from a 16" barrel?
Legitimate question. However I'm thinking you're narrowing the scope down to much, as a projectile hasn't been designed yet. I'd think we'd keep it open to the 105-115gr range, at a minimum.

...

IMO, a new Squad Common Cartridge/General Purpose Cartridge does not need to equal or exceed M80 ballistics, it just needs to provide the same engagement range capability. It seems to me that what's important is hit probability, not any specific trajectory, as indicated by use of the L129A1 and Mk48 weapons.

Completely agree.
