Grendel as a Universal Infantry Cartridge

[JASmith]

Too soon to tell.

Factors against:

• The 7.62 and 5.56 both do their respective jobs very well
  
• The logistics tail for both is extremely well entrenched
  
• A soldier can carry more rounds of 5.56
  
• Folks think the greater power of the 7.62 gives a serious advantage over the 6.5
  

Factors for:

• A 6.5 with characteristics like the Grendel can satisfy all of the ruoles currently filled by the 7.62 in dismounted operations
  
• The 6.5 has longer range than the 5.56 with larger bullets
  
• A soldier can carry more 6.5 rounds than he can 7.62 rounds
  
• The logistics tail would be significantly streamlined with a single caliber.
  

The biggest issue is that it takes more than "better than" these days to introduce something new.

So, while one cannot state definitively "no chance" the likelihood is not as high as we would like.
