Quote:The .280 British is about the maximum cartridge profile I would want to see for even a DMR duty position, as well as a Squad Light Machinegun/Auto Rifleman position.
This indicates that Riflemen should still have something smaller, and that the heavier cartridge of the mix should not exceed the .280 British profile for DMR and LMGs.
Ian indicates that the recoil impulse with .280 British in the EM-2 is more manageable than the 7.62 NATO, which can be calculated and compared looking at projectile weights, rifle weight, and chamber pressure.
