Not enough time to do a thorough analysis and response, but here's a very detailed article which argues against the 5.56 and in favor of the 7.62, http://www.globalsecurity.org/military/library/report/1986/MVT.htm ,which was interesting in and of itself, but I mention it here only because it's where I found the weights of the individual cartridges:
M855 with 62gr bullet weighs 182 grains
M80 with 147gr bullet weighs 386 grains
And 6.5 Grendel with 123gr bullet weighs ____ grains? [TX65! Please help!]
So a basic load of 5.56 totals 210 rounds at 186 grains each giving 38,220 grains. Divide that by 7000 (1 pound = 7000 grains) to give 5.46 pounds.
A basic load of 7.62 totals 210 rounds at 386 grains each giving 81,060 grains. Divide that by 7000 to give 11.58 pounds.
What I don't know is how the M240 MGs are assigned, versus the M16s and M249 SAWs. Certainly not one per squad. Who's up on current military organization, so we can get the total number of both 5.56 and 7.62 rounds in a given unit (squad? platoon? company?) which could theoretically be replaced by the 6.5 Grendel?
More analysis to come when we get 6.5 Grendel and weapons mix info.
