short and fat means faster more complete burn and greater power 300 Jamison is the round of choice in my book
308 just don't have the shock and awe of 30 06,

The 6.5x48mm or 6.5 MPC (Multi-Purpose Cartridge) was created to utilize the 5.56 casing but have a larger projectile for more stopping power.
I think the 6.8 SPC is the best all-around compromise on performance and stopping power. As I understand it, much of SOCOM is already using that round.
I remember when the the army was testing and considering the XM-8. I was hoping they would field it in a 6.8 SPC version, but at the time, there was some issues with performance because of errors in SAMMI specs.They worked it out but only after they decided not to go with or look more into that caliber.
If the military doesn't adopt it, I hope it sees more growth in the public sector. I have noticed more and more manufacturers offering rifles in that caliber though.
edit:: The 6.5 MPC has the benefit of allowing the continued use of the 5.56 NATO magazines and lower receivers, requiring only a change in barrel. This would give the 6.5 MPC would the advantage of a cheaper upgrade for the force, more capacity over the 6.8 SPC and thus be a lighter payload for the soldier.
I am not familiar with how much testing or consideration the military has given to the 6.5 MPC. If the military were to go to a new weapons platform, then I would hope to see it chambered in 6.8 SPC. If they were only going to upgrade (which in this economy may be the only option if any) then the 6.5 MPC may be something.
I agree with the author of the threat that the troops do need a better round than the 5.56.edit on 28-6-2011 by Wolf321 because: (no reason given)

Now keep in mind ive never been in the military. However theres just something about a 50 cal rifle that you gotta love. Now in between the 5.56 and the 7.62 id pick the 7.62 every time just for the sheer nock down power. However im not slandering the 5.56 i think there are benifits and detractors to both rounds. The 6.5 and 6.8 rounds that are being developed now try to get the best of both worlds. I dont really think in the argument between the two calibers there is a clear victor. Its more just based off of individual choice.
